History Of India

Anatomically modern humans first arrived on the Indian subcontinent between 73,000 and 55,000 years ago. Quote: "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka." The earliest known human remains in South Asia date to 30,000 years ago. Sedentariness began in South Asia around 7000 BCE; by 4500 BCE, settled life had spread, and gradually evolved into the Indus Valley Civilisation, which flourished between 2500 BCE and 1900 BCE in present-day Pakistan and north-western India. Early in the second millennium BCE, persistent drought caused the population of the Indus Valley to scatter from large urban centres to villages. Indo-Aryan tribes moved into the Punjab from Central Asia in several waves of migration. The Vedic Period of the Vedic people in northern India (1500–500 BCE) was marked by the composition of their extensive collections of hymns (Vedas). The social structure was loosely stratified via the varna system, incorporated into the highly evolved present-day Jāti system. The pastoral and nomadic Indo-Aryans spread from the Punjab into the Gangetic plain. Around 600 BCE, a new, interregional culture arose; then, small chieftaincies (janapadas) were consolidated into larger states (mahajanapadas). Second urbanization took place, which came with the rise of new ascetic movements and religious concepts, including the rise of Jainism and Buddhism. The latter was synthesized with the preexisting religious cultures of the subcontinent, giving rise to Hinduism.

Chandragupta Maurya overthrew the Nanda Empire and established the first great empire in ancient India, the Maurya Empire. India's Mauryan king Ashoka is widely recognised for his historical acceptance of Buddhism and his attempts to spread nonviolence and peace across his empire. The Maurya Empire would collapse in 185 BCE, on the assassination of the then-emperor Brihadratha by his general Pushyamitra Shunga. Shunga would form the Shunga Empire in the north and north-east of the subcontinent, while the Greco-Bactrian Kingdom would claim the north-west and found the Indo-Greek Kingdom. Various parts of India were ruled by numerous dynasties, including the Gupta Empire, in the 4th to 6th centuries CE. This period, witnessing a Hindu religious and intellectual resurgence is known as the Classical or Golden Age of India. Aspects of Indian civilisation, administration, culture, and religion spread to much of Asia, which led to the establishment of Indianised kingdoms in the region, forming Greater India.Flood, Gavin. Olivelle, Patrick. 2003. ''The Blackwell Companion to Hinduism''. Malden: Blackwell. pp. 273–274. The most significant event between the 7th and 11th centuries was the Tripartite struggle centred on Kannauj. Southern India saw the rise of multiple imperial powers from the middle of the fifth century. The Chola dynasty conquered southern India in the 11th century. In the early medieval period, Indian mathematics, including Hindu numerals, influenced the development of mathematics and astronomy in the Arab world, including the creation of the Hindu-Arabic numeral system.

Islamic conquests made limited inroads into modern Afghanistan and Sindh as early as the 8th century, followed by the invasions of Mahmud Ghazni.
The Delhi Sultanate was founded in 1206 by Central Asian Turks who were Indianized. They ruled a major part of the northern Indian subcontinent in the early 14th century. It was ruled by Multiple Turk, Afghan and Indian dynasties, Including the Turco-Mongol Indianized Tughlaq Dynasty but declined in the late 14th century following the invasions of Timur and saw the advent of the Malwa, Gujarat, and Bahmani Sultanates, the last of which split in 1518 into the five Deccan sultanates. The wealthy Bengal Sultanate also emerged as a major power, lasting over three centuries. During this period, multiple strong Hindu kingdoms, notably the Vijayanagara Empire and the Rajput states, emerged and played significant roles in shaping the cultural and political landscape of India.

The early modern period began in the 16th century, when the Mughal Empire conquered most of the Indian subcontinent, signaling the proto-industrialisation, becoming the biggest global economy and manufacturing power. The Mughals suffered a gradual decline in the early 18th century, largely due to the rising power of the Marathas, who took control of extensive regions of the Indian subcontinent. The East India Company, acting as a sovereign force on behalf of the British government, gradually acquired control of huge areas of India between the middle of the 18th and the middle of the 19th centuries. Policies of company rule in India led to the Indian Rebellion of 1857. India was afterwards ruled directly by the British Crown, in the British Raj. After World War I, a nationwide struggle for independence was launched by the Indian National Congress, led by Mahatma Gandhi. Later, the All-India Muslim League would advocate for a separate Muslim-majority nation state. The British Indian Empire was partitioned in August 1947 into the Dominion of India and Dominion of Pakistan, each gaining its independence.

Prehistoric era (until 3300 BCE)

Paleolithic

Hominin expansion from Africa is estimated to have reached the Indian subcontinent approximately two million years ago, and possibly as early as 2.2 million years ago. This dating is based on the known presence of ''Homo erectus'' in Indonesia by 1.8 million years ago and in East Asia by 1.36 million years ago, as well as the discovery of stone tools at Riwat in Pakistan. Although some older discoveries have been claimed, the suggested dates, based on the dating of fluvial sediments, have not been independently verified.

The oldest hominin fossil remains in the Indian subcontinent are those of ''Homo erectus'' or '' Homo heidelbergensis'', from the Narmada Valley in central India, and are dated to approximately half a million years ago. Older fossil finds have been claimed, but are considered unreliable. Reviews of archaeological evidence have suggested that occupation of the Indian subcontinent by hominins was sporadic until approximately 700,000 years ago, and was geographically widespread by approximately 250,000 years ago.

According to a historical demographer of South Asia, Tim Dyson:

Modern human beings—''Homo sapiens''—originated in Africa. Then, intermittently, sometime between 60,000 and 80,000 years ago, tiny groups of them began to enter the north-west of the Indian subcontinent. It seems likely that initially they came by way of the coast. It is virtually certain that there were ''Homo sapiens'' in the subcontinent 55,000 years ago, even though the earliest fossils that have been found of them date to only about 30,000 years before the present.

According to Michael D. Petraglia and Bridget Allchin:

Y-Chromosome and Mt-DNA data support the colonisation of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka.

Historian of South Asia, Michael H. Fisher, states:

Scholars estimate that the first successful expansion of the Homo sapiens range beyond Africa and across the Arabian Peninsula occurred from as early as 80,000 years ago to as late as 40,000 years ago, although there may have been prior unsuccessful emigrations. Some of their descendants extended the human range ever further in each generation, spreading into each habitable land they encountered. One human channel was along the warm and productive coastal lands of the Persian Gulf and northern Indian Ocean. Eventually, various bands entered India between 75,000 years ago and 35,000 years ago.

Archaeological evidence has been interpreted to suggest the presence of anatomically modern humans in the Indian subcontinent 78,000–74,000 years ago, although this interpretation is disputed. The occupation of South Asia by modern humans, initially in varying forms of isolation as hunter-gatherers, has turned it into a highly diverse one, second only to Africa in human genetic diversity.

According to Tim Dyson:

Genetic research has contributed to knowledge of the prehistory of the subcontinent's people in other respects. In particular, the level of genetic diversity in the region is extremely high. Indeed, only Africa's population is genetically more diverse. Related to this, there is strong evidence of 'founder' events in the subcontinent. By this is meant circumstances where a subgroup—such as a tribe—derives from a tiny number of 'original' individuals. Further, compared to most world regions, the subcontinent's people are relatively distinct in having practised comparatively high levels of endogamy.

Neolithic

Settled life emerged on the subcontinent in the western margins of the Indus River alluvium approximately 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE. According to Tim Dyson: "By 7,000 years ago agriculture was firmly established in Baluchistan... ndslowly spread eastwards into the Indus valley." Michael Fisher adds:

The earliest discovered instance ... of well-established, settled agricultural society is at Mehrgarh in the hills between the Bolan Pass and the Indus plain (today in Pakistan) (see Map 3.1). From as early as 7000 BCE, communities there started investing increased labor in preparing the land and selecting, planting, tending, and harvesting particular grain-producing plants. They also domesticated animals, including sheep, goats, pigs, and oxen (both humped zebu 'Bos indicus''and unhumped 'Bos taurus''. Castrating oxen, for instance, turned them from mainly meat sources into domesticated draft-animals as well.

Bronze Age (c. 3300 – 1800 BCE)

Indus Valley Civilisation

The Bronze Age in the Indian subcontinent began around 3300 BCE. The Indus Valley region was one of three early cradles of civilisation in the Old World; the Indus Valley civilisation was the most expansive, and at its peak, may have had a population of over five million.

The civilisation was primarily centred in modern-day Pakistan, in the Indus river basin, and secondarily in the Ghaggar-Hakra River basin. The mature Indus civilisation flourished from about 2600 to 1900 BCE, marking the beginning of urban civilisation on the Indian subcontinent. It included cities such as Harappa, Ganweriwal, and Mohenjo-daro in modern-day Pakistan, and Dholavira, Kalibangan, Rakhigarhi, and Lothal in modern-day India.

Inhabitants of the ancient Indus river valley, the Harappans, developed new techniques in metallurgy and handicraft, and produced copper, bronze, lead, and tin. The civilisation is noted for its cities built of brick, and its roadside drainage system, and is thought to have had some kind of municipal organisation. The civilisation also developed an Indus script, the earliest of the ancient Indian scripts, which is presently undeciphered. This is the reason why Harappan language is not directly attested, and its affiliation uncertain.

After the collapse of Indus Valley civilisation, the inhabitants migrated from the river valleys of Indus and Ghaggar-Hakra, towards the Himalayan foothills of Ganga-Yamuna basin.

Ochre Coloured Pottery culture

During 2nd millennium BCE, Ochre Coloured Pottery culture was in Ganga Yamuna Doab region. These were rural settlements with agriculture and hunting. They were using copper tools such as axes, spears, arrows, and swords, and had domesticated animals.

Iron Age ( 1800 – 200 BCE)

Vedic period ( 1500 – 600 BCE)

Starting 1900 BCE, Indo-Aryan tribes moved into the Punjab from Central Asia in several waves of migration. The Vedic period is when the Vedas were composed of liturgical hymns from the Indo-Aryan people. The Vedic culture was located in part of north-west India, while other parts of India had a distinct cultural identity. Many regions of the Indian subcontinent transitioned from the Chalcolithic to the Iron Age in this period.

The Vedic culture is described in the texts of Vedas, still sacred to Hindus, which were orally composed and transmitted in Vedic Sanskrit. The Vedas are some of the oldest extant texts in India. The Vedic period, lasting from about 1500 to 500 BCE, contributed the foundations of several cultural aspects of the Indian subcontinent.

Vedic society

Historians have analysed the Vedas to posit a Vedic culture in the Punjab, and the upper Gangetic Plain. The Peepal tree and cow were sanctified by the time of the Atharva Veda. Many of the concepts of Indian philosophy espoused later, like dharma, trace their roots to Vedic antecedents.

Early Vedic society is described in the Rigveda, the oldest Vedic text, believed to have been compiled during the 2nd millennium BCE, in the north-western region of the Indian subcontinent. At this time, Aryan society consisted of predominantly tribal and pastoral groups, distinct from the Harappan urbanisation which had been abandoned. The early Indo-Aryan presence probably corresponds, in part, to the Ochre Coloured Pottery culture in archaeological contexts.Michael Witzel (1989), ''Tracing the Vedic dialects'' in ''Dialectes dans les litteratures Indo-Aryennes'' ed. Caillat, Paris, 97–265.

At the end of the Rigvedic period, the Aryan society expanded from the north-western region of the Indian subcontinent into the western Ganges plain. It became increasingly agricultural and was socially organised around the hierarchy of the four '' varnas'', or social classes. This social structure was characterised both by syncretising with the native cultures of northern India but also eventually by the excluding of some indigenous peoples by labelling their occupations impure. During this period, many of the previous small tribal units and chiefdoms began to coalesce into Janapadas (monarchical, state-level polities).

Sanskrit epics

The Sanskrit epics ''Ramayana'' and ''Mahabharata'' were composed during this period. The ''Mahabharata'' remains the longest single poem in the world. Historians formerly postulated an "epic age" as the milieu of these two epic poems, but now recognise that the texts went through multiple stages of development over centuries. The existing texts of these epics are believed to belong to the post-Vedic age, between 400 BCE and 400 CE.

Janapadas

The Iron Age in the Indian subcontinent from about 1200 BCE to the 6th century BCE is defined by the rise of Janapadas, which are realms, republics and kingdoms—notably the Iron Age Kingdoms of Kuru, Panchala, Kosala and Videha.

The Kuru Kingdom ( 1200–450 BCE) was the first state-level society of the Vedic period, corresponding to the beginning of the Iron Age in north-western India, around 1200–800 BCE, as well as with the composition of the Atharvaveda. The Kuru state organised the Vedic hymns into collections and developed the srauta ritual to uphold the social order. Two key figures of the Kuru state were king Parikshit and his successor Janamejaya, who transformed this realm into the dominant political, social, and cultural power of northern India. When the Kuru kingdom declined, the centre of Vedic culture shifted to their eastern neighbours, the Panchala kingdom. The archaeological PGW (Painted Grey Ware) culture, which flourished in north-eastern India's Haryana and western Uttar Pradesh regions from about 1100 to 600 BCE, is believed to correspond to the Kuru and Panchala kingdoms.

During the Late Vedic Period, the kingdom of Videha emerged as a new centre of Vedic culture, situated even farther to the East (in what is today Nepal and Bihar state); reaching its prominence under the king Janaka, whose court provided patronage for Brahmin sages and philosophers such as Yajnavalkya, Aruni, and Gārgī Vāchaknavī. The later part of this period corresponds with a consolidation of increasingly large states and kingdoms, called ''Mahajanapadas'', across Northern India.

Second urbanisation ( 600 – 200 BCE)

The period between 800 and 200 BCE saw the formation of the '' Śramaṇa'' movement, from which Jainism and Buddhism originated. The first Upanishads were written during this period. After 500 BCE, the so-called "second urbanisation" started, with new urban settlements arising at the Ganges plain. The foundations for the "second urbanisation" were laid prior to 600 BCE, in the Painted Grey Ware culture of the Ghaggar-Hakra and Upper Ganges Plain; although most PGW sites were small farming villages, "several dozen" PGW sites eventually emerged as relatively large settlements that can be characterised as towns, the largest of which were fortified by ditches or moats and embankments made of piled earth with wooden palisades.

The Central Ganges Plain, where Magadha gained prominence, forming the base of the Maurya Empire, was a distinct cultural area, with new states arising after 500 BCE. It was influenced by the Vedic culture, but differed markedly from the Kuru-Panchala region. "It was the area of the earliest known cultivation of rice in South Asia and by 1800 BCE was the location of an advanced Neolithic population associated with the sites of Chirand and Chechar". In this region, the Śramaṇic movements flourished, and Jainism and Buddhism originated.

Buddhism and Jainism

The time between 800 BCE and 400 BCE witnessed the composition of the earliest Upanishads, which form the theoretical basis of classical Hinduism, and are also known as the ''Vedanta'' (conclusion of the Vedas).

The increasing urbanisation of India in the 7th and 6th centuries BCE led to the rise of new ascetic or "Śramaṇa movements" which challenged the orthodoxy of rituals. Mahavira ( 599–527 BCE), proponent of Jainism, and Gautama Buddha ( 563–483 BCE), founder of Buddhism, were the most prominent icons of this movement. Śramaṇa gave rise to the concept of the cycle of birth and death, the concept of samsara, and the concept of liberation. Buddha found a Middle Way that ameliorated the extreme asceticism found in the '' Śramaṇa'' religions.

Around the same time, Mahavira (the 24th ''Tirthankara'' in Jainism) propagated a theology that was to later become Jainism. However, Jain orthodoxy believes the teachings of the ''Tirthankaras'' predates all known time and scholars believe Parshvanatha (c. 872 – c. 772 BCE), accorded status as the 23rd ''Tirthankara'', was a historical figure. The Vedas are believed to have documented a few ''Tirthankaras'' and an ascetic order similar to the ''Śramaṇa'' movement.

Mahajanapadas

The period from 600 BCE to 300 BCE witnessed the rise of the Mahajanapadas, sixteen powerful and vast kingdoms and oligarchic republics. These Mahajanapadas evolved and flourished in a belt stretching from Gandhara in the north-west to Bengal in the eastern part of the Indian subcontinent and included parts of the trans-Vindhyan region. Ancient Buddhist texts, like the '' Aṅguttara Nikāya'', make frequent reference to these sixteen great kingdoms and republics—Anga, Assaka, Avanti, Chedi, Gandhara, Kashi, Kamboja, Kosala, Kuru, Magadha, Malla, Matsya (or Machcha), Panchala, Surasena, Vṛji, and Vatsa. This period saw the second major rise of urbanism in India after the Indus Valley Civilisation.

Early "republics" or , such as Shakyas, Koliyas, Mallakas, and Licchavis had republican governments. s, such as the Mallakas, centered in the city of Kusinagara, and the Vajjika League, centred in the city of Vaishali, existed as early as the 6th century BCE and persisted in some areas until the 4th century CE. The most famous clan amongst the ruling confederate clans of the Vajji Mahajanapada were the Licchavis.

This period corresponds in an archaeological context to the Northern Black Polished Ware culture. Especially focused in the Central Ganges plain but also spreading across vast areas of the northern and central Indian subcontinent, this culture is characterised by the emergence of large cities with massive fortifications, significant population growth, increased social stratification, wide-ranging trade networks, construction of public architecture and water channels, specialised craft industries, a system of weights, punch-marked coins, and the introduction of writing in the form of Brahmi and Kharosthi scripts. The language of the gentry at that time was Sanskrit, while the languages of the general population of northern India are referred to as Prakrits.

Many of the sixteen kingdoms had merged into four major ones by the time of Gautama Buddha. These four were Vatsa, Avanti, Kosala, and Magadha.

Early Magadha dynasties

Magadha formed one of the sixteen Mahajanapadas (Sanskrit: "Great Realms") or kingdoms in ancient India. The core of the kingdom was the area of Bihar south of the Ganges; its first capital was Rajagriha (modern Rajgir) then Pataliputra (modern Patna). Magadha expanded to include most of Bihar and Bengal with the conquest of Licchavi and Anga respectively, followed by much of eastern Uttar Pradesh and Orissa. The ancient kingdom of Magadha is heavily mentioned in Jain and Buddhist texts. It is also mentioned in the Ramayana, Mahabharata and Puranas. The earliest reference to the Magadha people occurs in the Atharva-Veda where they are found listed along with the Angas, Gandharis, and Mujavats. Magadha played an important role in the development of Jainism and Buddhism. Republican communities (such as the community of Rajakumara) are merged into Magadha kingdom. Villages had their own assemblies under their local chiefs called Gramakas. Their administrations were divided into executive, judicial, and military functions.

Early sources, from the Buddhist Pāli Canon, the Jain Agamas and the Hindu Puranas, mention Magadha being ruled by the Pradyota dynasty and Haryanka dynasty ( 544–413 BCE) for some 200 years, 600–413 BCE. King Bimbisara of the Haryanka dynasty led an active and expansive policy, conquering Anga in what is now eastern Bihar and West Bengal. King Bimbisara was overthrown and killed by his son, Prince Ajatashatru, who continued the expansionist policy of Magadha. During this period, Gautama Buddha, the founder of Buddhism, lived much of his life in the Magadha kingdom. He attained enlightenment in Bodh Gaya, gave his first sermon in Sarnath and the first Buddhist council was held in Rajgriha. The Haryanka dynasty was overthrown by the Shaishunaga dynasty ( 413–345 BCE). The last Shishunaga ruler, Kalasoka, was assassinated by Mahapadma Nanda in 345 BCE, the first of the so-called Nine Nandas (Mahapadma Nanda and his eight sons).

Nanda Empire and Alexander's campaign

The Nanda Empire ( 345–322 BCE), at its peak, extended from Bengal in the east, to the Punjab in the west and as far south as the Vindhya Range. The Nanda dynasty built on the foundations laid by their Haryanka and Shishunaga predecessors. Nanda empire have built a vast army, consisting of 200,000 infantry, 20,000 cavalry, 2,000 war chariots and 3,000 war elephants (at the lowest estimates).

Maurya Empire

The Maurya Empire (322–185 BCE) unified most of the Indian subcontinent into one state, and was the largest empire ever to exist on the Indian subcontinent. At its greatest extent, the Mauryan Empire stretched to the north up to the natural boundaries of the Himalayas and to the east into what is now Assam. To the west, it reached beyond modern Pakistan, to the Hindu Kush mountains in what is now Afghanistan. The empire was established by Chandragupta Maurya assisted by Chanakya ( Kautilya) in Magadha (in modern Bihar) when he overthrew the Nanda Empire.

Chandragupta rapidly expanded his power westwards across central and western India, and by 317 BCE the empire had fully occupied north-western India. The Mauryan Empire defeated Seleucus I, founder of the Seleucid Empire, during the Seleucid–Mauryan war, thus gained additional territory west of the Indus River. Chandragupta's son Bindusara succeeded to the throne around 297 BCE. By the time he died in 272 BCE, a large part of the Indian subcontinent was under Mauryan suzerainty. However, the region of Kalinga (around modern day Odisha) remained outside Mauryan control, perhaps interfering with trade with the south.

Bindusara was succeeded by Ashoka, whose reign lasted until his death in about 232 BCE. His campaign against the Kalingans in about 260 BCE, though successful, led to immense loss of life and misery. This led Ashoka to shun violence, and subsequently to embrace Buddhism. The empire began to decline after his death and the last Mauryan ruler, Brihadratha, was assassinated by Pushyamitra Shunga to establish the Shunga Empire.

Under Chandragupta Maurya and his successors, internal and external trade, agriculture, and economic activities all thrived and expanded across India thanks to the creation of a single efficient system of finance, administration, and security. The Mauryans built the Grand Trunk Road, one of Asia's oldest and longest major roads connecting the Indian subcontinent with Central Asia. After the Kalinga War, the Empire experienced nearly half a century of peace and security under Ashoka. Mauryan India also enjoyed an era of social harmony, religious transformation, and expansion of scientific knowledge. Chandragupta Maurya's embrace of Jainism increased social and religious renewal and reform across his society, while Ashoka's embrace of Buddhism has been said to have been the foundation of the reign of social and political peace and non-violence across India. Ashoka sponsored Buddhist missions into Sri Lanka, Southeast Asia, West Asia, North Africa, and Mediterranean Europe.

The ''Arthashastra'' written by Chanakya and the Edicts of Ashoka are the primary written records of the Mauryan times. Archaeologically, this period falls in the era of Northern Black Polished Ware. The Mauryan Empire was based on a modern and efficient economy and society in which the sale of merchandise was closely regulated by the government. Although there was no banking in the Mauryan society, usury was customary. A significant amount of written records on slavery are found, suggesting a prevalence thereof. During this period, a high-quality steel called Wootz steel was developed in south India and was later exported to China and Arabia.''Technology and Society'' by Menon, R.V.G. p. 15

Sangam period

During the Sangam period Tamil literature flourished from the 3rd century BCE to the 4th century CE. Three Tamil dynasties, collectively known as the Three Crowned Kings of Tamilakam: Chera dynasty, Chola dynasty, and the Pandya dynasty ruled parts of southern India.

The Sangam literature deals with the history, politics, wars, and culture of the Tamil people of this period. Unlike Sanskrit writers who were mostly Brahmins, Sangam writers came from diverse classes and social backgrounds and were mostly non-Brahmins.''The First Spring: The Golden Age of India'' by Abraham Eraly p. 655

Around  300 BCE –  200 CE, Pathupattu, an anthology of ten mid-length book collections, which is considered part of Sangam Literature, were composed; the composition of eight anthologies of poetic works Ettuthogai as well as the composition of eighteen minor poetic works Patiṉeṇkīḻkaṇakku; while Tolkāppiyam, the earliest grammarian work in the Tamil language was developed. Also, during Sangam period, two of the Five Great Epics of Tamil Literature were composed. Ilango Adigal composed ''Silappatikaram'', which is a non-religious work, that revolves around Kannagi, and ''Manimekalai'', composed by Chithalai Chathanar, is a sequel to ''Silappatikaram'', and tells the story of the daughter of Kovalan and Madhavi, who became a Buddhist Bhikkhuni.

Classical period (c. 200 BCE – c. 650 CE)

The time between the Maurya Empire in the 3rd century BCE and the end of the Gupta Empire in the 6th century CE is referred to as the "Classical" period of India. The Gupta Empire (4th–6th century) is regarded as the "Golden Age" of Hinduism, although a host of kingdoms ruled over India in these centuries. Also, the Sangam literature flourished from the 3rd century BCE to the 3rd century CE in southern India.''A Social History of Early India'' by Brajadulal Chattopadhyaya p. 259 During this period, India's economy is estimated to have been the largest in the world, having between one-third and one-quarter of the world's wealth, from 1 CE to 1000 CE.

Early classical period (c. 200 BCE – c. 320 CE)

Shunga Empire

The Shungas originated from Magadha, and controlled large areas of the central and eastern Indian subcontinent from around 187 to 78 BCE. The dynasty was established by Pushyamitra Shunga, who overthrew the last Maurya emperor. Its capital was Pataliputra, but later emperors, such as Bhagabhadra, also held court at Vidisha, modern Besnagar.

Pushyamitra Shunga ruled for 36 years and was succeeded by his son Agnimitra. There were ten Shunga rulers. However, after the death of Agnimitra, the empire rapidly disintegrated; inscriptions and coins indicate that much of northern and central India consisted of small kingdoms and city-states that were independent of any Shunga hegemony. The empire is noted for its numerous wars with both foreign and indigenous powers. They fought with the Mahameghavahana dynasty of Kalinga, Satavahana dynasty of Deccan, the Indo-Greeks, and possibly the Panchalas and Mitras of Mathura.

Art, education, philosophy, and other forms of learning flowered during this period including architectural monuments such as the Stupa at Bharhut and the renowned Great Stupa at Sanchi. The Shunga rulers helped to establish the tradition of royal sponsorship of learning and art. The script used by the empire was a variant of Brahmi and was used to write the Sanskrit language. The Shunga Empire played an imperative role in patronising Indian culture at a time when some of the most important developments in Hindu thought were taking place.

Satavahana Empire

The Śātavāhanas were based from Amaravati in Andhra Pradesh as well as Junnar (Pune) and Prathisthan ( Paithan) in Maharashtra. The territory of the empire covered large parts of India from the 1st century BCE onward. The Sātavāhanas started out as feudatories to the Mauryan dynasty, but declared independence with its decline.

The Sātavāhanas are known for their patronage of Hinduism and Buddhism, which resulted in Buddhist monuments from Ellora (a UNESCO World Heritage Site) to Amaravati. They were one of the first Indian states to issue coins with their rulers embossed. They formed a cultural bridge and played a vital role in trade as well as the transfer of ideas and culture to and from the Indo-Gangetic Plain to the southern tip of India.

They had to compete with the Shunga Empire and then the Kanva dynasty of Magadha to establish their rule. Later, they played a crucial role to protect large part of India against foreign invaders like the Sakas, Yavanas and Pahlavas. In particular, their struggles with the Western Kshatrapas went on for a long time. The notable rulers of the Satavahana Dynasty Gautamiputra Satakarni and Sri Yajna Sātakarni were able to defeat the foreign invaders like the Western Kshatrapas and to stop their expansion. In the 3rd century CE, the empire was split into smaller states.

Trade and travels to India

The spice trade in Kerala attracted traders from all over the Old World to India. India's Southwest coastal port Muziris had established itself as a major spice trade centre from as early as 3,000 BCE, according to Sumerian records. Jewish traders arrived in Kochi, Kerala, India as early as 562 BCE. The Greco-Roman world followed by trading along the incense route and the Roman-India routes. During the 2nd century BCE Greek and Indian ships met to trade at Arabian ports such as Aden. During the first millennium, the sea routes to India were controlled by the Indians and Ethiopians that became the maritime trading power of the Red Sea.

Indian merchants involved in spice trade took Indian cuisine to Southeast Asia, where spice mixtures and curries became popular with the native inhabitants. Buddhism entered China through the Silk Road in the 1st or 2nd century CE. Hindu and Buddhist religious establishments of South and Southeast Asia came to be centres of production and commerce as they accumulated capital donated by patrons. They engaged in estate management, craftsmanship, and trade. Buddhism in particular travelled alongside the maritime trade, promoting literacy, art, and the use of coinage.

Kushan Empire

The Kushan Empire expanded out of what is now Afghanistan into the northwest of the Indian subcontinent under the leadership of their first emperor, Kujula Kadphises, about the middle of the 1st century CE. The Kushans were possibly a Tocharian speaking tribe, one of five branches of the Yuezhi confederation. By the time of his grandson, Kanishka the Great, the empire spread to encompass much of Afghanistan, and then the northern parts of the Indian subcontinent.

Emperor Kanishka was a great patron of Buddhism; however, as Kushans expanded southward, the deities of their later coinage came to reflect its new Hindu majority. Historian Vincent Smith said about Kanishka:

The empire linked the Indian Ocean maritime trade with the commerce of the Silk Road through the Indus valley, encouraging long-distance trade, particularly between China and Rome. The Kushans brought new trends to the budding and blossoming Gandhara art and Mathura art, which reached its peak during Kushan rule. The period of peace under Kushan rule is known as '' Pax Kushana''. By the 3rd century, their empire in India was disintegrating and their last known great emperor was Vasudeva I.

Classical period (c. 320 – 650 CE)

Gupta Empire

The Gupta period was noted for cultural creativity, especially in literature, architecture, sculpture, and painting. The Gupta period produced scholars such as Kalidasa, Aryabhata, Varahamihira, Vishnu Sharma, and Vatsyayana. The Gupta period marked a watershed of Indian culture: the Guptas performed Vedic sacrifices to legitimise their rule, but they also patronised Buddhism, an alternative to Brahmanical orthodoxy. The military exploits of the first three rulers – Chandragupta I, Samudragupta, and Chandragupta II – brought much of India under their leadership. Science and political administration reached new heights during the Gupta era. Strong trade ties also made the region an important cultural centre and established it as a base that would influence nearby kingdoms and regions. The period of peace under Gupta rule is known as '' Pax Gupta''.

The latter Guptas successfully resisted the northwestern kingdoms until the arrival of the Alchon Huns, who established themselves in Afghanistan by the first half of the 5th century CE, with their capital at Bamiyan. However, much of the southern India including Deccan were largely unaffected by these events.

Vakataka Empire

The Vākāṭaka Empire originated from the Deccan in the mid-third century CE. Their state is believed to have extended from the southern edges of Malwa and Gujarat in the north to the Tungabhadra River in the south as well as from the Arabian Sea in the western to the edges of Chhattisgarh in the east. They were the most important successors of the Satavahanas in the Deccan, contemporaneous with the Guptas in northern India and succeeded by the Vishnukundina dynasty.

The Vakatakas are noted for having been patrons of the arts, architecture and literature. The rock-cut Buddhist viharas and chaityas of Ajanta Caves (a UNESCO World Heritage Site) were built under the patronage of Vakataka emperor, Harishena.

Kamarupa Kingdom

Samudragupta's 4th-century Allahabad pillar inscription mentions Kamarupa ( Western Assam) and Davaka (Central Assam) as frontier kingdoms of the Gupta Empire. Davaka was later absorbed by Kamarupa, which grew into a large kingdom that spanned from Karatoya river to near present Sadiya and covered the entire Brahmaputra valley, North Bengal, parts of Bangladesh and, at times Purnea and parts of West Bengal.

Ruled by three dynasties Varmanas (c. 350–650 CE), Mlechchha dynasty (c. 655–900 CE) and Kamarupa-Palas (c. 900–1100 CE), from their capitals in present-day Guwahati (Pragjyotishpura), Tezpur (Haruppeswara) and North Gauhati (Durjaya) respectively. All three dynasties claimed their descent from Narakasura. In the reign of the Varman king, Bhaskar Varman (c. 600–650 CE), the Chinese traveller Xuanzang visited the region and recorded his travels. Later, after weakening and disintegration (after the Kamarupa-Palas), the Kamarupa tradition was somewhat extended until c. 1255 CE by the Lunar I (c. 1120–1185 CE) and Lunar II (c. 1155–1255 CE) dynasties. The Kamarupa kingdom came to an end in the middle of the 13th century when the Khen dynasty under Sandhya of Kamarupanagara (North Guwahati), moved his capital to Kamatapur (North Bengal) after the invasion of Muslim Turks, and established the Kamata kingdom.

Pallava Empire

The Pallavas, during the 4th to 9th centuries were, alongside the Guptas of the North, great patronisers of Sanskrit development in the South of the Indian subcontinent. The Pallava reign saw the first Sanskrit inscriptions in a script called Grantha. Early Pallavas had different connexions to Southeast Asian countries. The Pallavas used Dravidian architecture to build some very important Hindu temples and academies in Mamallapuram, Kanchipuram and other places; their rule saw the rise of great poets. The practice of dedicating temples to different deities came into vogue followed by fine artistic temple architecture and sculpture style of Vastu Shastra.

Pallavas reached the height of power during the reign of Mahendravarman I (571–630 CE) and Narasimhavarman I (630–668 CE) and dominated the Telugu and northern parts of the Tamil region until the end of the 9th century.

Kadamba Empire

Kadambas originated from Karnataka, was founded by Mayurasharma in 345 CE which at later times showed the potential of developing into imperial proportions. King Mayurasharma defeated the armies of Pallavas of Kanchi possibly with help of some native tribes. The Kadamba fame reached its peak during the rule of Kakusthavarma, a notable ruler with whom the kings of Gupta Dynasty of northern India cultivated marital alliances. The Kadambas were contemporaries of the Western Ganga Dynasty and together they formed the earliest native kingdoms to rule the land with absolute autonomy. The dynasty later continued to rule as a feudatory of larger Kannada empires, the Chalukya and the Rashtrakuta empires, for over five hundred years during which time they branched into minor dynasties ( Kadambas of Goa, Kadambas of Halasi and Kadambas of Hangal).

Empire of Harsha

Harsha ruled northern India from 606 to 647 CE. He was the son of Prabhakarvardhana and the younger brother of Rajyavardhana, who were members of the Vardhana dynasty and ruled Thanesar, in present-day Haryana.

After the downfall of the prior Gupta Empire in the middle of the 6th century, North India reverted to smaller republics and monarchical states. The power vacuum resulted in the rise of the Vardhanas of Thanesar, who began uniting the republics and monarchies from the Punjab to central India. After the death of Harsha's father and brother, representatives of the empire crowned Harsha emperor in April 606 CE, giving him the title of Maharaja.RN Kundra & SS Bawa, History of Ancient and Medieval India At the peak, his Empire covered much of North and Northwestern India, extended East until Kamarupa, and South until Narmada River; and eventually made Kannauj (in present Uttar Pradesh) his capital, and ruled until 647 CE.International Dictionary of Historic Places: Asia and Oceania by Trudy Ring, Robert M. Salkin, Sharon La Boda p. 507

The peace and prosperity that prevailed made his court a centre of cosmopolitanism, attracting scholars, artists and religious visitors. During this time, Harsha converted to Buddhism from Surya worship. The Chinese traveller Xuanzang visited the court of Harsha and wrote a very favourable account of him, praising his justice and generosity. His biography ''Harshacharita'' ("Deeds of Harsha") written by Sanskrit poet Banabhatta, describes his association with Thanesar and the palace with a two-storied ''Dhavalagriha'' (White Mansion).

Early medieval period (mid 6th – 1200)

Early medieval India began after the end of the Gupta Empire in the 6th century CE. This period also covers the "Late Classical Age" of Hinduism, which began after the collapse of the Empire of Harsha in the 7th century, and ended in the 13th century with the rise of the Delhi Sultanate in Northern India; the beginning of Imperial Kannauj, leading to the Tripartite struggle; and the end of the Later Cholas with the death of Rajendra Chola III in 1279 in Southern India; however some aspects of the Classical period continued until the fall of the Vijayanagara Empire in the south around the 17th century.

From the fifth century to the thirteenth, Śrauta sacrifices declined, and initiatory traditions of Buddhism, Jainism or more commonly Shaivism, Vaishnavism and Shaktism expanded in royal courts. This period produced some of India's finest art, considered the epitome of classical development, and the development of the main spiritual and philosophical systems which continued to be in Hinduism, Buddhism and Jainism.

In the 7th century, Kumārila Bhaṭṭa formulated his school of Mimamsa philosophy and defended the position on Vedic rituals against Buddhist attacks. Scholars note Bhaṭṭa's contribution to the decline of Buddhism in India. In the 8th century, Adi Shankara travelled across the Indian subcontinent to propagate and spread the doctrine of Advaita Vedanta, which he consolidated; and is credited with unifying the main characteristics of the current thoughts in Hinduism. He was a critic of both Buddhism and Minamsa school of Hinduism;Edward Roer (Translator), to ''Brihad Aranyaka Upanishad'' at pp. 3–4; Quote – " ..Lokayatikas and Bauddhas who assert that the soul does not exist. There are four sects among the followers of Buddha: 1. Madhyamicas who maintain all is void; 2. Yogacharas, who assert except sensation and intelligence all else is void; 3. Sautranticas, who affirm actual existence of external objects no less than of internal sensations; 4. Vaibhashikas, who agree with later (Sautranticas) except that they contend for immediate apprehension of exterior objects through images or forms represented to the intellect."Edward Roer (Translator), to ''Brihad Aranyaka Upanishad'' at p. 3, and founded mathas (monasteries) for the spread and development of Advaita Vedanta. Muhammad bin Qasim's invasion of Sindh (modern Pakistan) in 711 witnessed further decline of Buddhism.

From the 8th to the 10th century, three dynasties contested for control of northern India: the Gurjara Pratiharas of Malwa, the Palas of Bengal, and the Rashtrakutas of the Deccan. The Sena dynasty would later assume control of the Pala Empire; the Gurjara Pratiharas fragmented into various states, notably the Kingdom of Malwa, the Kingdom of Bundelkhand, the Kingdom of Dahala, the Tomaras of Haryana, and the Kingdom of Sambhar, these states were some of the earliest Rajput kingdoms; while the Rashtrakutas were annexed by the Western Chalukyas. During this period, the Chaulukya dynasty emerged; the Chaulukyas constructed the Dilwara Temples, Modhera Sun Temple, Rani ki vav in the style of Māru-Gurjara architecture, and their capital Anhilwara (modern Patan, Gujarat) was one of the largest cities in the Indian subcontinent, with the population estimated at 100,000 in 1000.

The Chola Empire emerged as a major power during the reign of Raja Raja Chola I and Rajendra Chola I who successfully invaded parts of Southeast Asia and Sri Lanka in the 11th century.''The Dancing Girl: A History of Early India'' by Balaji Sadasivan p. 129 Lalitaditya Muktapida (r. 724–760 CE) was an emperor of the Kashmiri Karkoṭa dynasty, which exercised influence in northwestern India from 625 until 1003, and was followed by Lohara dynasty. Kalhana in his Rajatarangini credits king Lalitaditya with leading an aggressive military campaign in Northern India and Central Asia.

The Hindu Shahi dynasty ruled portions of eastern Afghanistan, northern Pakistan, and Kashmir from the mid-7th century to the early 11th century. While in Odisha, the Eastern Ganga Empire rose to power; noted for the advancement of Hindu architecture, most notable being Jagannath Temple and Konark Sun Temple ruled large parts of southern and central India between the 6th and the 12th centuries, as three related yet individual dynasties. The earliest dynasty, known as the "Badami Chalukyas", ruled from Vatapi (modern Badami) from the middle of the 6th century. The Badami Chalukyas began to assert their independence at the decline of the Kadamba kingdom of Banavasi and rapidly rose to prominence during the reign of Pulakeshin II. The rule of the Chalukyas marks an important milestone in the history of South India and a golden age in the history of Karnataka. The political atmosphere in South India shifted from smaller kingdoms to large empires with the ascendancy of Badami Chalukyas. A Southern India-based kingdom took control and consolidated the entire region between the Kaveri and the Narmada Rivers. The rise of this empire saw the birth of efficient administration, overseas trade and commerce and the development of new style of architecture called "Chalukyan architecture". The Chalukya dynasty ruled parts of southern and central India from Badami in Karnataka between 550 and 750, and then again from Kalyani between 970 and 1190.

Rashtrakuta Empire

Founded by Dantidurga around 753, the Rashtrakuta Empire ruled from its capital at Manyakheta for almost two centuries. At its peak, the Rashtrakutas ruled from the Ganges-Yamuna Doab in the north to Cape Comorin in the south, a fruitful time of architectural and literary achievements.

The early rulers of this dynasty were Hindu, but the later rulers were strongly influenced by Jainism. Govinda III and Amoghavarsha were the most famous of the long line of able administrators produced by the dynasty. Amoghavarsha was also an author and wrote Kavirajamarga, the earliest known Kannada work on poetics. Architecture reached a milestone in the Dravidian style, the finest example of which is seen in the Kailasanath Temple at Ellora. Other important contributions are the Kashivishvanatha temple and the Jain Narayana temple at Pattadakal in Karnataka.

The Arab traveller Suleiman described the Rashtrakuta Empire as one of the four great Empires of the world. The Rashtrakuta period marked the beginning of the golden age of southern Indian mathematics. The great south Indian mathematician Mahāvīra had a huge impact on medieval south Indian mathematicians. The Rashtrakuta rulers also patronised men of letters in a variety of languages.

Gurjara-Pratihara Empire

The Gurjara-Pratiharas were instrumental in containing Arab armies moving east of the Indus River. Nagabhata I defeated the Arab army under Junaid and Tamin during the Umayyad campaigns in India. Under Nagabhata II, the Gurjara-Pratiharas became the most powerful dynasty in northern India. He was succeeded by his son Ramabhadra, who ruled briefly before being succeeded by his son, Mihira Bhoja. Under Bhoja and his successor Mahendrapala I, the Pratihara Empire reached its peak of prosperity and power. By the time of Mahendrapala, its territory stretched from the border of Sindh in the west to Bihar in the east and from the Himalayas in the north to around the Narmada River in the south. The expansion triggered a tripartite power struggle with the Rashtrakuta and Pala empires for control of the Indian subcontinent.

By the end of the 10th century, several feudatories of the empire took advantage of the temporary weakness of the Gurjara-Pratiharas to declare their independence, notably the Kingdom of Malwa, the Kingdom of Bundelkhand, the Tomaras of Haryana, and the Kingdom of Sambhar and the Kingdom of Dahala.

Gahadavala dynasty

Gahadavala dynasty ruled parts of the present-day Indian states of Uttar Pradesh and Bihar, during 11th and 12th centuries. Their capital was located at Varanasi.

Khayaravala dynasty

The Khayaravala dynasty, ruled parts of the present-day Indian states of Bihar and Jharkhand, during 11th and 12th centuries. Their capital was located at Khayaragarh in Shahabad district. Pratapdhavala and Shri Pratapa were king of the dynasty.

Pala Empire

The Pala Empire was founded by Gopala I. It was ruled by a Buddhist dynasty from Bengal. The Palas reunified Bengal after the fall of Shashanka's Gauda Kingdom.

The Palas were followers of the Mahayana and Tantric schools of Buddhism, they also patronised Shaivism and Vaishnavism. The empire reached its peak under Dharmapala and Devapala. Dharmapala is believed to have conquered Kanauj and extended his sway up to the farthest limits of India in the north-west.

The Pala Empire can be considered as the golden era of Bengal. Dharmapala founded the Vikramashila and revived Nalanda, considered one of the first great universities in recorded history. Nalanda reached its height under the patronage of the Pala Empire. The Palas also built many viharas. They maintained close cultural and commercial ties with countries of Southeast Asia and Tibet. Sea trade added greatly to the prosperity of the Pala Empire.

Cholas

Medieval Cholas rose to prominence during the middle of the 9th century and established the greatest empire South India had seen. They successfully united the South India under their rule and through their naval strength extended their influence in the Southeast Asian countries such as Srivijaya. Under Rajaraja Chola I and his successors Rajendra Chola I, Rajadhiraja Chola, Virarajendra Chola and Kulothunga Chola I the dynasty became a military, economic and cultural power in South Asia and South-East Asia.: The Cholas were in fact the most successful dynasty since the Guptas ... The classic expansion of Chola power began anew with the accession of Rajaraja I in 985. Rajendra Chola I's navies occupied the sea coasts from Burma to Vietnam, the Andaman and Nicobar Islands, the Lakshadweep (Laccadive) islands, Sumatra, and the Malay Peninsula. The power of the new empire was proclaimed to the eastern world by the expedition to the Ganges which Rajendra Chola I undertook and by the occupation of cities of the maritime empire of Srivijaya in Southeast Asia, as well as by the repeated embassies to China.K. A. Nilakanta Sastri, ''A History of South India'', p. 158

They dominated the political affairs of Sri Lanka for over two centuries through repeated invasions and occupation. They also had continuing trade contacts with the Arabs and the Chinese empire. Rajaraja Chola I and his son Rajendra Chola I gave political unity to the whole of Southern India and established the Chola Empire as a respected sea power. Under the Cholas, the South India reached new heights of excellence in art, religion and literature. In all of these spheres, the Chola period marked the culmination of movements that had begun in an earlier age under the Pallavas. Monumental architecture in the form of majestic temples and sculpture in stone and bronze reached a finesse never before achieved in India.

Western Chalukya Empire

The Western Chalukya Empire ruled most of the western Deccan, South India, between the 10th and 12th centuries.A Comprehensive History of Medieval India: by Farooqui Salma Ahmed, Salma Ahmed Farooqui p. 24 Vast areas between the Narmada River in the north and Kaveri River in the south came under Chalukya control. During this period the other major ruling families of the Deccan, the Hoysalas, the Seuna Yadavas of Devagiri, the Kakatiya dynasty and the Southern Kalachuris, were subordinates of the Western Chalukyas and gained their independence only when the power of the Chalukya waned during the latter half of the 12th century.

The Western Chalukyas developed an architectural style known today as a transitional style, an architectural link between the style of the early Chalukya dynasty and that of the later Hoysala empire. Most of its monuments are in the districts bordering the Tungabhadra River in central Karnataka. Well known examples are the Kasivisvesvara Temple at Lakkundi, the Mallikarjuna Temple at Kuruvatti, the Kallesvara Temple at Bagali, Siddhesvara Temple at Haveri, and the Mahadeva Temple at Itagi. This was an important period in the development of fine arts in Southern India, especially in literature as the Western Chalukya kings encouraged writers in the native language of Kannada, and Sanskrit like the philosopher and statesman Basava and the great mathematician Bhāskara II.

Late medieval period ( 1200–1526)

The late medieval period is marked by repeated invasions of the Muslim Central Asian nomadic clans, the rule of the Delhi sultanate, and by the growth of other dynasties and empires, built upon military technology of the Sultanate. It turned from a turkic Monopoly to an Indianized Indo-Muslim polity

Delhi Sultanate

The Delhi Sultanate was a series of successive Islamic states based in Delhi, ruled by several dynasties of Turkic, Indic,Turko-IndianWilliam Hunter (1903), , 23rd Edition, pp. 124–127 and Pashtun origins. It ruled large parts of the Indian subcontinent from the 13th to the early 16th century.Delhi Sultanate
''Encyclopædia Britannica'' In the 12th and 13th centuries, Central Asian Turks invaded parts of northern India and established the Delhi Sultanate in the former Hindu holdings. The subsequent Mamluk dynasty of Delhi managed to conquer large areas of northern India, while the Khalji dynastys.

The Sultanate ushered in a period of Indian cultural renaissance. The resulting "Indo-Muslim" fusion of cultures left lasting syncretic monuments in architecture, music, literature, religion, and clothing. It is surmised that the language of Urdu
