Historical India

According to consensus in modern genetics, anatomically modern humans first arrived on the Indian subcontinent from Africa 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." However, the earliest known human remains in South Asia date to 30,000 years ago. Settled life, which involves the transition from foraging to farming and pastoralism, began in South Asia around 7000 BCE. At the site of Mehrgarh presence can be documented of the domestication of wheat and barley, rapidly followed by that of goats, sheep, and cattle. By 4500 BCE, settled life had spread more widely, and began to gradually evolve into the Indus Valley civilisation, an early civilisation of the Old World, which was contemporaneous with Ancient Egypt and Mesopotamia. This civilisation flourished between 2500 BCE and 1900 BCE in what today is Pakistan and north-western India, and was noted for its urban planning, baked brick houses, elaborate drainage, and water supply.

Early on in the second millennium BCE, persistent drought caused the population of the Indus Valley to scatter from large urban centres to villages. Around the same time, Indo-Aryan tribes moved into the Punjab from Central Asia in several waves of migration. Their Vedic Period (1500–500 BCE) was marked by the composition of the Vedas, large collections of hymns of these tribes. Their varna system, which evolved into the caste system, consisted of a hierarchy of priests, warriors, and free peasants. The pastoral and nomadic Indo-Aryans spread from the Punjab into the Gangetic plain, large swaths of which they deforested for agriculture usage. The composition of Vedic texts ended around 600 BCE, when a new, interregional culture arose. Small chieftaincies, or janapadas, were consolidated into larger states, or mahajanapadas, and a second urbanisation took place. This urbanisation was accompanied by the rise of new ascetic movements in Greater Magadha, including Jainism and Buddhism, which opposed the growing influence of Brahmanism and the primacy of rituals, presided by Brahmin priests, that had come to be associated with Vedic religion, and gave rise to new religious concepts. In response to the success of these movements, Vedic Brahmanism was synthesised with the preexisting religious cultures of the subcontinent, giving rise to Hinduism.

Most of the Indian subcontinent was conquered by the Maurya Empire during the 4th and 3rd centuries BCE. From the 3rd century BCE onwards, Prakrit and Pali literature in the north and Tamil Sangam literature in southern India started to flourish.''A Social History of Early India'' by Brajadulal Chattopadhyaya p. 259 Wootz steel originated in south India in the 3rd century BCE and was exported.''Technology and Society'' by Menon, R.V.G. p. 15 The Maurya Empire would collapse in 185 BCE, on the assassination of the then-Emperor Brihadratha by his General Pushyamitra Shunga. Shunga would go on to form the Shunga Empire in the North and Northeast of the subcontinent, while the Greco-Bactrian Kingdom would claim the Northwest, and found the Indo-Greek Kingdom. During this Classical period, various parts of India were ruled by numerous dynasties, including the Gupta Empire in the 4-6th centuries CE. This period, witnessing a Hindu religious and intellectual resurgence, is known as the classical or "Golden Age of India". During this period, aspects of Indian civilisation, administration, culture, and religion (Hinduism and Buddhism) spread to much of Asia, while kingdoms in southern India had maritime business links with the Middle East and the Mediterranean. Indian cultural influence spread over many parts of Southeast Asia, which led to the establishment of Indianised kingdoms in Southeast Asia ( 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 century was the Tripartite struggle centred on Kannauj that lasted for more than two centuries between the Pala Empire, Rashtrakuta Empire, and Gurjara-Pratihara Empire. Southern India saw the rise of multiple imperial powers from the middle of the fifth century, most notably the Chalukya, Chola, Pallava, Chera, Pandyan, and Western Chalukya Empires. The Chola dynasty conquered southern India and successfully invaded parts of Southeast Asia, Sri Lanka, the Maldives, and Bengal 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.

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 CE by Central Asian Turks who ruled a major part of the northern Indian subcontinent in the early 14th century, but declined in the late 14th century, and saw the advent of the Deccan sultanates. The wealthy Bengal Sultanate also emerged as a major power, lasting over three centuries.
This period also saw the emergence of several powerful Hindu states, notably Vijayanagara and Rajput states, such as Mewar. The 15th century saw the advent of Sikhism. The early modern period began in the 16th century, when the Mughal Empire conquered most of the Indian subcontinent, signalling the proto-industrialization, becoming the biggest global economy and manufacturing power, with a nominal GDP that valued a quarter of world GDP, superior than the combination of Europe's GDP. The Mughals suffered a gradual decline in the early 18th century, which provided opportunities for the Marathas, Sikhs, Mysoreans, Nizams, and Nawabs of Bengal to exercise control over large regions of the Indian subcontinent.

From the mid-18th century to the mid-19th century, large regions of India were gradually annexed by the East India Company, a chartered company acting as a sovereign power on behalf of the British government. Dissatisfaction with company rule in India led to the Indian Rebellion of 1857, which rocked parts of north and central India, and led to the dissolution of the company. 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, and noted for nonviolence. 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 c. 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 before the present. This dating is based on the known presence of '' Homo erectus'' in Indonesia by 1.8 million years before the present and in East Asia by 1.36 million years before present, as well as the discovery of stone tools at Riwat in the Soan River valley of the Pabbi Hills region, 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 before the present, from which point onward, archaeological evidence of proto-human presence is widely mentioned.

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 colonization of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka.

And according to historian of South Asia, Michael H. Fisher:

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, over a long time, 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. And, over the next 2,000 years, the practice of farming slowly spread eastwards into the Indus valley." And according to Michael Fisher:

"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 – c. 1800 BCE)

Indus Valley Civilisation

The Bronze Age in the Indian subcontinent began around 3300 BCE. Along with Ancient Egypt and Mesopotamia, the Indus Valley region was one of three early cradles of civilization of the Old World. Of the three, 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 centered in modern-day Pakistan, in the Indus river basin, and secondarily in the Ghaggar-Hakra River basin in eastern Pakistan and northwestern India. The mature Indus civilisation flourished from about 2600 to 1900 BCE, marking the beginning of urban civilisation on the Indian subcontinent. The civilisation included cities such as Harappa, Ganeriwala, and Mohenjo-daro, Kalibangan, Rakhigarhi, and Lothal in modern-day India.

Inhabitants of the ancient Indus river valley, the Harappans, developed new techniques in metallurgy and handicraft (carneol products, seal carving), and produced copper, bronze, lead, and tin. The civilisation is noted for its cities built of brick, roadside drainage system, and multi-storeyed houses and is thought to have had some kind of municipal organisation. Civilization also developed a Indus script, which is presently undeciphered. This is the reason why Harappan language is not directly attested, and its affiliation uncertain. A relationship or membership of the Dravidian or Elamo-Dravidian language family is proposed by some scholars.

After the collapse of Indus Valley civilisation, the inhabitants of the Indus Valley civilisation 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 settlement with agriculture and hunting. They were using copper tools such as axes, spears, arrows, and swords. The people had domesticated cattle, goats, sheep, horses, pigs and dogs. The site gained attention for its Bronze Age solid-disk wheel carts, found in 2018, which were interpreted by some as horse-pulled " chariots".

Iron Age (c. 1800 – 200 BCE)

Vedic period (c. 1500 – 600 BCE)

Starting ca. 1900 BCE, Indo-Aryan tribes moved into the Punjab from Central Asia in several waves of migration. The Vedic period is the period when the Vedas were composed, the 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 during this period. 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 region 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 2nd millennium BCE, in the northwestern region of the Indian subcontinent. At this time, Aryan society consisted of largely 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 began to expand from the northwestern 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 characterized both by syncretising with the native cultures of northern India, but also eventually by the excluding of some indigenous peoples by labeling their occupations impure. During this period, many of the previous small tribal units and chiefdoms began to coalesce into Janapadas (monarchical, state-level polities).

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, Videha.

The Kuru Kingdom (c. 1200–450 BCE) was the first state-level society of the Vedic period, corresponding to the beginning of the Iron Age in northwestern India, around 1200–800 BCE, as well as with the composition of the Atharvaveda (the first Indian text to mention iron, as , literally "black metal"). 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, transforming this realm into the dominant political, social, and cultural power of northern Iron Age 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 the Haryana and western Uttar Pradesh regions of northern India 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 in India); 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'', all across Northern India.

Second urbanisation (c. 600 – 200 BCE)

The period between 800 and 200 BCE saw the formation of ''Śramaṇa'' movement from 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, especially the Central 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 characterized as towns, the largest of which were fortified by ditches or moats and embankments made of piled earth with wooden palisades, albeit smaller and simpler than the elaborately fortified large cities which grew after 600 BCE in the Northern Black Polished Ware culture.

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 during the so-called "second urbanisation". 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. The Upanishads form the theoretical basis of classical Hinduism, and are also known as 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 (c. 549–477 BCE), proponent of Jainism, and Gautama Buddha (c. 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.

Sanskrit epics

The Sanskrit epics ''Ramayana'' and ''Mahabharata'' were composed during this period. The ''Mahabharata'' remains, till this day, the longest single poem in the world. Historians formerly postulated an "epic age" as the milieu of these two epic poems, but now recognize that the texts (which are both familiar with each other) went through multiple stages of development over centuries. For instance, the ''Mahabharata'' may have been based on a small-scale conflict (possibly about 1000 BCE) which was eventually "transformed into a gigantic epic war by bards and poets". Archaeology cannot conclusively prove or disprove the historicity related to the epics. The existing texts of these epics are believed to belong to the post-Vedic age, between c. 400 BCE and 400 CE.

Mahajanapadas

The period from c. 600 BCE to c. 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 northwest 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, centered 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 characterized 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, specialized craft industries (e.g., ivory and carnelian carving), 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 coalesced into four major ones by 500/400 BCE, by the time of Gautama Buddha. These four were Vatsa, Avanti, Kosala, and Magadha. The life of Gautama Buddha was mainly associated with these four kingdoms.

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. The Magadha kingdom included republican communities such as the community of Rajakumara. 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 (c. 544–413 BCE) for some 200 years, c. 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 (c. 413–345 BCE). The last Shishunaga ruler, Kalasoka, was assassinated by Mahapadma Nanda in 345 BCE, the first of the so-called Nine Nandas, which were Mahapadma and his eight sons.

Nanda Empire and Alexander's campaign

The Nanda Empire (c. 345–322 BCE), at its greatest extent, extended from Bengal in the east, to the Punjab region in the west and as far south as the Vindhya Range. The Nanda dynasty was famed for their great wealth. The Nanda dynasty built on the foundations laid by their Haryanka and Shishunaga predecessors to create the first great empire of north India. To achieve this objective they 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). According to the Greek historian Plutarch, the size of the Nanda army was even larger, numbering 200,000 infantry, 80,000 cavalry, 8,000 war chariots, and 6,000 war elephants. However, the Nanda Empire did not have the opportunity to see their army face Alexander the Great, who invaded north-western India at the time of Dhana Nanda, since Alexander was forced to confine his campaign to the plains of Punjab and Sindh, for his forces mutinied at the river Beas and refused to go any further upon encountering Nanda and Gangaridai forces.

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 Northwestern India. The Mauryan Empire then defeated Seleucus I, a diadochus and 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 c. 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 their trade with the south.

Bindusara was succeeded by Ashoka, whose reign lasted for around 37 years 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 filled Ashoka with remorse and led him 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 the sciences and of 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 all of India. Ashoka sponsored the spreading of Buddhist missionaries into Sri Lanka, Southeast Asia, West Asia, North Africa, and Mediterranean Europe.

The '' Arthashastra'' wrote by Chanakya and the Edicts of Ashoka are the primary written records of the Mauryan times. Archaeologically, this period falls into the era of Northern Black Polished Ware. The Mauryan Empire was based on a modern and efficient economy and society. However, 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.

Sangam period

During the Sangam period Tamil literature flourished from the 3rd century BCE to the 4th century CE. During this period, 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. The scholars of the Sangam period rose from among the common people who sought the patronage of the Tamil Kings, but who mainly wrote about the common people and their concerns.''The First Spring: The Golden Age of India'' by Abraham Eraly p. 655 Unlike Sanskrit writers who were mostly Brahmins, Sangam writers came from diverse classes and social backgrounds and were mostly non-Brahmins. They belonged to different faiths and professions such as farmers, artisans, merchants, monks, and priests, including also royalty and women.

Around c. 300 BCE – c. 200 CE, Pathupattu, an anthology of ten mid-length books collection, 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, who having lost her husband to a miscarriage of justice at the court of the Pandyan dynasty, wreaks her revenge on his kingdom, 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 Bikkuni.Mukherjee 1999, p. 277

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. It can be divided in various sub-periods, depending on the chosen periodisation. Classical period begins after the decline of the Maurya Empire, and the corresponding rise of the Shunga Empire and Satavahana dynasty. 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. 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 in Eastern Malwa.

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 battles 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 small terracotta images, larger stone sculptures, and 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. This helped the empire flourish and gain power.

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 struck 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. Early writings and Stone Age carvings of Neolithic age obtained indicates that India's Southwest coastal port Muziris, in Kerala, had established itself as a major spice trade centre from as early as 3,000 BCE, according to Sumerian records traders from Judea arrived in Kochi, Kerala, India as early as 562 BCE.
* Buddhism entered China through the Silk Road transmission of Buddhism in the 1st or 2nd century CE. The interaction of cultures resulted in several Chinese travellers and monks to enter India. Most notable were Faxian, Yijing, Song Yun and Xuanzang. These travellers wrote detailed accounts of the Indian subcontinent, which includes the political and social aspects of the region.
* Hindu and Buddhist religious establishments of Southeast Asia came to be associated with the economic activity and commerce as patrons entrust large funds which would later be used to benefit the local economy by estate management, craftsmanship, promotion of trading activities. Buddhism in particular, travelled alongside the maritime trade, promoting coinage, art, and literacy. Indian merchants involved in spice trade took Indian cuisine to Southeast Asia, where spice mixtures and curries became popular with the native inhabitants.
* 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.

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 of 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 at least as far as Saketa and Sarnath near Varanasi (Banaras).

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. They played an important role in the establishment of Buddhism in India and its spread to Central Asia and China.

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.

H.G. Rowlinson commented:

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 who made great advancements in many academic fields. The Gupta period marked a watershed of Indian culture: the Guptas performed Vedic sacrifices to legitimise their rule, but they also patronised Buddhism, which continued to provide 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 in: Sri Lanka; Maritime Southeast Asia (Brunei, Indonesia, Malaysia, Philippines, Singapore, and Timor-Leste); as well as Indochina (Cambodia, Laos, Myanmar, Thailand, and Vietnam).

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 in the north.

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. They led public works and their monuments are a visible legacy. 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, an immigrant from Aryavarta. 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 for about six hundred years 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, an indication to which is provided by the titles and epithets assumed by its rulers. 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 even 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 known as the 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 at an assembly in April 606 CE, giving him the title of Maharaja when he was merely 16 years old.RN Kundra & SS Bawa, History of Ancient and Medieval India At the height of his power, 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 state) 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 from far and wide. 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, besides mentioning the defence wall, a moat and the palace with a two-storied ''Dhavalagriha'' (White Mansion).

Early medieval period (mid 6th c.–1200 CE)

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 end of the Gupta Empire, and the collapse of the Empire of Harsha in the 7th century CE; the beginning of Imperial Kannauj, leading to the Tripartite struggle; and ended in the 13th century with the rise of the Delhi Sultanate in Northern India 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 CE, 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;Shyama Kumar Chattopadhyaya (2000) ''The Philosophy of Sankar's Advaita Vedanta''
Sarup & Sons, New Delhi 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), in the four corners of the Indian subcontinent for the spread and development of Advaita Vedanta.The Seven Spiritual Laws Of Yoga
Deepak Chopra, John Wiley & Sons, 2006, While, Muhammad bin Qasim's invasion of Sindh (modern Pakistan) in 711 CE witnessed further decline of Buddhism. The Chach Nama records many instances of conversion of stupas to mosques such as at Nerun.

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 Paramaras of Malwa, the Chandelas of Bundelkhand, the Kalachuris of Mahakoshal, the Tomaras of Haryana, and the Chauhans of Rajputana, 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 CE.

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 CE 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
