The West suffered more heavily from these decades of crisis due to this distinction between the established and more prosperous Hellenised East and the younger colonized and Romanized West that had persisted. This cultural division of the Roman Empire into an eastern Greek and western Latin part became increasingly important in later centuries, leading to a gradual estrangement of the two Roman worlds. Emperor Diocletian created the administrative system known as the

The dominate was in comparison with the principate, a huge imperial bureaucracy, which laid the foundations for the power structure of the later Eastern Roman Empire. With this came a redistricting and reduction of Roman provinces. Diocletian scrapped any pretense of republican rule as the emperor moved away from formally being merely "Princeps" to being "Dominus" - Lord and master. Diocletian also formally finished the process of restructuring the empire, from being a colonial-styled empire ruled by Rome and Roman Italians in the first century AD to a larger imperial entity where the emperor's court was not bound to the city of Rome or Italy, now only one Roman imperial province among many. The norm of emperors being Roman Italians was first broken by emperor

By 602, a series of successful Byzantine campaigns had pushed the Avars and Slavs back across the Danube. However, Maurice's refusal to ransom several thousand captives taken by the Avars, and his order to the troops to winter in the Danube, caused his popularity to plummet. A revolt broke out under an officer named Phocas, who marched the troops back to Constantinople; Maurice and his family were murdered while trying to escape.

Early Heraclian dynasty

After Maurice's murder by
Phocas Phocas ( la, Focas; grc-gre, Φωκάς, Phōkás; 5475 October 610) was Eastern Roman emperor from 602 to 610. Initially, a middle-ranking officer in the Eastern Roman army, Phocas rose to prominence as a spokesman for dissatisfied soldiers ...

Phocas, an unpopular ruler invariably described in Byzantine sources as a "tyrant", was the target of a number of Senate-led plots. He was eventually deposed in 610 by Heraclius, who sailed to Constantinople from Carthage with an icon affixed to the prow of his ship. Following the accession of Heraclius, the Sassanid advance pushed deep into the

First Arab siege of Constantinople (674–678) and the theme system

. However, the Anatolian raids continued unabated and accelerated the demise of classical urban culture, with the inhabitants of many cities either refortifying much smaller areas within the old city walls or relocating entirely to nearby fortresses. Constantinople shrank substantially from 500,000 inhabitants to just 40,000–70,000, and, like other urban centres, it was partly ruralised. The city also lost the free grain shipments in 618, after Egypt fell first to the Persians and then to the Arabs, and public wheat distribution ceased. The void left by the disappearance of the old semi-autonomous civic institutions was filled by the system called ''theme'', which entailed dividing Asia Minor into "provinces" occupied by distinct armies that assumed civil authority and answered directly to the imperial administration. This system may have had its roots in certain ''ad hoc'' measures taken by Heraclius, but over the course of the 7th century it developed into an entirely new system of imperial governance. The massive cultural and institutional restructuring of the empire consequent on the loss of territory in the 7th century has been said to have caused a decisive break in east Mediterranean ''Romanness'', and that the Byzantine state is subsequently best understood as another successor state rather than a real continuation of the Roman Empire.


Late Heraclian dynasty

The withdrawal of large numbers of troops from the Balkans to combat the Persians and then the Arabs in the east opened the door for the gradual southward expansion of Slavic peoples into the peninsula, and, as in Asia Minor, many cities shrank to small fortified settlements. In the 670s, the

, which ruled for 150 years. This dynasty included some of the ablest emperors in Byzantium's history, and the period is one of revival. The empire moved from defending against external enemies to reconquest of territories.. The Macedonian dynasty was characterised by a cultural revival in spheres such as philosophy and the arts. There was a conscious effort to restore the brilliance of the period before the Slavic and subsequent Arab invasions, and the Macedonian era has been dubbed the "Golden Age" of Byzantium. Although the empire was significantly smaller than during the reign of Justinian I, it had regained much strength, as the remaining territories were less geographically dispersed and more politically, economically, and culturally integrated.

. Even after the Christianisation of the Rus', however, relations were not always friendly. The most serious conflict between the two powers was an invasion of Bulgaria in 968, but several Rus' raiding expeditions against the Byzantine cities of the Black Sea coast and Constantinople are also recorded. Although most were repulsed, they were often followed by treaties that were generally favourable to the Rus', such as the one concluded at the end of the war of 1043, during which the Rus' indicated their ambitions to compete with the Byzantines as an independent power.

. These were not temporary tactical gains but long-term reconquests. Leo VI achieved the complete codification of Byzantine law in Greek. This monumental work of 60 volumes became the foundation of all subsequent Byzantine law and is still studied today.. Leo also reformed the administration of the empire, redrawing the borders of the administrative subdivisions (the ''

'', or "themes") and tidying up the system of ranks and privileges, as well as regulating the behaviour of the various trade guilds in Constantinople. Leo's reform did much to reduce the previous fragmentation of the empire, which henceforth had one centre of power, Constantinople.. However, the increasing military success of the empire greatly enriched and gave the provincial nobility more power over the peasantry, who were essentially reduced to a state of serfdom.. Under the Macedonian emperors Constantinople flourished, becoming the largest and wealthiest city in Europe, with a population of approximately 400,000 in the 9th and 10th centuries. During this period, the Byzantine Empire employed a strong civil service staffed by competent aristocrats that oversaw the collection of taxes, domestic administration, and foreign policy. The Macedonian emperors also increased the empire's wealth by fostering trade with Western Europe, particularly through the sale of silk and metalwork.


Split between Orthodoxy and Catholicism (1054)

The Macedonian period included events of momentous religious significance. The conversion of the Bulgarians, Serbs and Rus' to Orthodox Christianity drew the religious map of Europe which still resonates today.
Cyril and Methodius Cyril (born Constantine, 826–869) and Methodius (815–885) were two brothers and Byzantine Christian theologians and missionaries. For their work evangelizing the Slavs, they are known as the "Apostles to the Slavs". They are credited wit ...

Crisis and fragmentation

The Byzantine Empire fell into a period of difficulties, caused to a large extent by the undermining of the theme system and the neglect of the military. Nikephoros II, John Tzimiskes, and Basil II shifted the emphasis of the military divisions (, '' tagmata'') from a reactive, defence-oriented citizen army into an army of professional career soldiers, increasingly dependent on foreign mercenaries. Mercenaries were expensive, however, and as the threat of invasion receded in the 10th century, so did the need for maintaining large garrisons and expensive fortifications. Basil II left a burgeoning treasury upon his death, but he neglected to plan for his succession. None of his immediate successors had any particular military or political talent, and the imperial administration increasingly fell into the hands of the civil service. Incompetent efforts to revive the Byzantine economy resulted in severe inflation and a debased gold currency. The army was seen as both an unnecessary expense and a political threat. A number of standing local units were demobilised, further augmenting the army's dependence on mercenaries, who could be retained and dismissed on an as-needed basis.Markham,

Venetian and other Italian traders became resident in large numbers in Constantinople and the empire (there were an estimated 60,000 Latins in Constantinople alone, out of a population of three to four hundred thousand), and their presence together with the numerous Latin mercenaries who were employed by Manuel helped to spread Byzantine technology, art, literature and culture throughout the Latin West, while also leading to a flow of Western ideas and customs into the empire.

to recover Jerusalem and the East from the Muslims. The response in Western Europe was overwhelming. Alexios had anticipated help in the form of mercenary forces from the West, but he was totally unprepared for the immense and undisciplined force that arrived in Byzantine territory. It was no comfort to Alexios to learn that four of the eight leaders of the main body of the Crusade were Normans, among them Bohemund. Since the crusade had to pass through Constantinople, however, the emperor had some control over it. He required its leaders to swear to restore to the empire any towns or territories they might reconquer from the Turks on their way to the Holy Land. In return, he gave them guides and a military escort. Alexios was able to recover a number of important cities, islands and much of western Asia Minor. The Crusaders agreed to become Alexios' vassals under the

12th-century Renaissance

John and Manuel pursued active military policies, and both deployed considerable resources on sieges and city defences; aggressive fortification policies were at the heart of their imperial military policies.. Despite the defeat at Myriokephalon, the policies of Alexios, John and Manuel resulted in vast territorial gains, increased frontier stability in Asia Minor, and secured the stabilisation of the empire's European frontiers. From c. 1081 to c. 1180, the Komnenian army assured the empire's security, enabling Byzantine civilisation to flourish.. This allowed the Western provinces to achieve an economic revival that continued until the close of the century. It has been argued that Byzantium under the Komnenian rule was more prosperous than at any time since the Persian invasions of the 7th century. During the 12th century, population levels rose and extensive tracts of new agricultural land were brought into production. Archaeological evidence from both Europe and Asia Minor shows a considerable increase in the size of urban settlements, together with a notable upsurge in new towns. Trade was also flourishing; the Venetians, the Genoese and others opened up the ports of the Aegean to commerce, shipping goods from the Crusader states and Fatimid Egypt to the west and trading with the empire via Constantinople.; .

In philosophy, there was a resurgence of classical learning not seen since the 7th century, characterised by a significant increase in the publication of commentaries on classical works.. Besides, the first transmission of classical Greek knowledge to the West occurred during the Komnenian period.. In terms of prosperity and cultural life, the Komnenian period was one of the peaks in Byzantine history, and Constantinople remained the leading city of the Christian world in size, wealth, and culture.

The aristocrats were infuriated against him, and to make matters worse, Andronikos seems to have become increasingly unbalanced; executions and violence became increasingly common, and his reign turned into a reign of terror. Andronikos seemed almost to seek the extermination of the aristocracy as a whole.

, but the war-ravaged empire was ill-equipped to deal with the enemies that surrounded it. To maintain his campaigns against the Latins, Michael pulled troops from Asia Minor and levied crippling taxes on the peasantry, causing much resentment. Massive construction projects were completed in Constantinople to repair the damage of the Fourth Crusade, but none of these initiatives was of any comfort to the farmers in Asia Minor suffering raids from Muslim ghazis.. Rather than holding on to his possessions in Asia Minor, Michael chose to expand the empire, gaining only short-term success. To avoid another sacking of the capital by the Latins, he forced the Church to submit to Rome, again a temporary solution for which the peasantry hated Michael and Constantinople. The efforts of Andronikos II and later his grandson Andronikos III marked Byzantium's last genuine attempts in restoring the glory of the empire. However, the use of mercenaries by Andronikos II often backfired, with the

Government and bureaucracy

As established by the Hellenistic political systems, the List of Byzantine emperors, monarch was the sole and Autocracy, absolute ruler, and his power was regarded as having divine origin. From Justinian I on, the emperor was considered ''nomos empsychos'', the "living law", both lawgiver and administrator. The Byzantine senate, senate had ceased to have real political and legislative authority but remained as an honorary council with titular members, resembling an emergency or ceremonial meeting made up of powerful Constantinopolitan aristocrats, very often friends and relatives of the emperor. By the end of the 8th century, a civil administration focused on the court was formed as part of a large-scale consolidation of power in the capital (the rise to pre-eminence of the position of ''sakellarios'' is related to this change).; . As a result of the differring Orthodox and Diadochi, Hellenistic political systems philosophies, from Justinian onwards, an administrative simplification was given way for the emperor's easier management of the state as the sole administrator and lawgiver of the sacred Ecumene, Oikoumene. Definitive powers began to be attached around single entities who acted as viceroys, starting with the exarch, ''exarchs'' and their Justinianic-era predecessors ''stratelates'' who shared the extraordinary powers of the emperor in their respective districts and only answered to him, they also being appointed by the emperor directly. The most important administrative reform, which probably started in the mid-7th century, was the creation of Theme (Byzantine district), themes, where civil and military administration were embodied in a single person, the ''strategos,'' who, as the emperor's viceroy, shared his extraordinary powers in their respective "''thémata''", they too being also appointed by the emperor alone.; . Despite the occasionally derogatory use of the terms "Byzantine" and "Byzantinism", the Byzantine bureaucracy had a distinct ability for adapting to the empire's changing situations. The elaborate system of titulature and precedence gave the court prestige and influence. Officials were arranged in strict order around the emperor and depended upon the royal will for their ranks. There were also actual administrative jobs, but authority could be vested in individuals rather than offices.; . In the 8th and 9th centuries, civil service had constituted the clearest path to aristocratic status. However, beginning from the 9th century, the civil aristocracy was rivalled by an aristocracy of nobility. According to some studies of the Byzantine government, 11th-century politics were dominated by competition between the civil and the military aristocracy. During this period, Alexios I undertook important administrative reforms, including the creation of new courtly dignities and offices..


Diplomacy

After the fall of Rome, the key challenge to the empire was maintaining relations with its neighbours. When these nations set about forging formal political institutions, they were often modelled after Constantinople. Byzantine diplomacy managed to draw its neighbours into a network of international and inter-state relations.. This network revolved around treaty-making and included the welcoming of the new ruler into the family of kings and the assimilation of Byzantine social attitudes, values and institutions. Whereas classical writers are fond of making ethical and legal distinctions between peace and war, Byzantines regarded diplomacy as a form of war by other means. For example, a Bulgarian threat could be countered by providing money to the Kievan Rus'.. Diplomacy was understood to have an intelligence-gathering function on top of its pure political function. The Bureau of Barbarians in Constantinople handled matters of protocol and record-keeping for any issues related to the "Barbarian, barbarians", and thus had, perhaps, a basic intelligence function itself. J. B. Bury, John B. Bury believes that the office exercised supervision over all foreigners visiting Constantinople, and that they were under the supervision of the Logothetes tou dromou. While on the surface a protocol office—its main duty was to ensure foreign envoys were properly cared for and received sufficient state funds for their maintenance, and it kept all the official translators—it probably had a security function as well. Byzantines availed themselves of several diplomatic practices. For example, embassies to the capital often stayed on for years. A member of other royal houses would routinely be requested to stay on in Constantinople as a potential hostage as well as a useful pawn in case political conditions changed. Another key practice was to overwhelm visitors by sumptuous displays. According to Dimitri Obolensky, the preservation of the ancient civilisation in Europe could be accredited to the skill and resourcefulness of Byzantine diplomacy, which remains one of Byzantium's lasting contributions to the history of Europe..

''. Justinian's reforms had a clear effect on the evolution of jurisprudence, with his ''Corpus'' becoming the basis for medieval Roman law, revived Roman law in the Western world, while Leo III's ''Ecloga'' influenced the formation of legal institutions in the Slavic world. In the 10th century, Leo VI the Wise achieved the complete codification of the whole of Byzantine law in Greek with the ''Basilika'', which became the foundation of all subsequent Byzantine law with an influence extending through to modern Balkan legal codes.

. The University of Constantinople, Imperial University of Constantinople, sometimes known as the ''University of the Palace Hall of Magnaura'' ( el, Πανδιδακτήριον τῆς Μαγναύρας), was an Eastern Roman Empire, Eastern Roman educational institution that could trace its corporate origins to AD 425, when Emperor Theodosius II founded the ''Pandidakterion'' ( grc-x-byzant, Πανδιδακτήριον). The Pandidakterion was refounded in 1046 by Constantine IX Monomachos who created the Departments of Law (Διδασκαλεῖον τῶν Νόμων) and Philosophy (Γυμνάσιον). At the time various economic schools, colleges, polytechnics, libraries and fine arts academies also operated in the city of Constantinople. And a few scholars have gone so far as to call the Pandidakterion the first "university" in the world.Marina Loukaki: "Université. Domaine byzantin", in: ''Dictionnaire encyclopédique du Moyen Âge'', Vol. 2, Éditions du Cerf, Paris, 1997, , p. 1553: The writings of classical antiquity were cultivated and preserved in Byzantium.

was the first to question Aristotelian physics. Unlike Aristotle, who based his physics on verbal argument, Philoponus relied on observation. Philoponus' criticism of Aristotelian principles of physics was an inspiration for Galileo Galilei's refutation of Aristotelian physics during the Scientific Revolution many centuries later, as Galileo cites Philoponus substantially in his works.Lindberg, David. (1992) ''The Beginnings of Western Science''. University of Chicago Press. p. 162. The Byzantines pioneered the concept of the hospital as an institution offering medical care and the possibility of a cure for the patients, as a reflection of the ideals of Christian charity, rather than merely a place to die. Greek fire, an incendiary weapon which could even burn on water, is attributed to the Byzantines. It played a crucial role in the empire's victory over the Umayyad Caliphate during the siege of Constantinople (717–718). The discovery is attributed to Callinicus of Heliopolis from Syria who fled during the Arab conquest of Syria. However, it has also been argued that no single person invented Greek fire, but rather, that it was "invented by the chemists in Constantinople who had inherited the discoveries of the Alexandrian chemical school...".Partington, J.R. (1999). "A History of Greek Fire and Gunpowder". The Johns Hopkins University Press. p. 13. In the final century of the empire, astronomy and other mathematics, mathematical sciences were taught in Trebizond; medicine attracted the interest of almost all scholars.. The Fall of Constantinople in 1453 fuelled the era later commonly known as the "Italian Renaissance". During this period, Greek scholars in the Renaissance, refugee Byzantine scholars were principally responsible for carrying, in person and writing, ancient Greek grammatical, literary studies, mathematical, and astronomical knowledge to early Renaissance Italy. They also brought with them classical learning and texts on botany, medicine and zoology, as well as the works of Dioscorides and John Philoponus' criticism of Aristotelian physics.


Culture


Religion

The Byzantine Empire was a theocracy, said to be ruled by God in Christianity, God working through the emperor. Jennifer Fretland VanVoorst argues, "The Byzantine Empire became a theocracy in the sense that Christian values and ideals were the foundation of the empire's political ideals and heavily entwined with its political goals." Steven Runciman says in his book: The survival of the empire in the East assured an active role of the emperor in the affairs of the Church. The Byzantine state inherited from pagan times the administrative and financial routine of administering religious affairs, and this routine was applied to the Christian Church. Following the pattern set by Eusebius of Caesarea, the Byzantines viewed the emperor as a representative or messenger of Jesus, Christ, responsible particularly for the propagation of Christianity among pagans, and for the "externals" of the religion, such as administration and finances. As Cyril Mango points out, the Byzantine political thinking can be summarised in the motto "One God, one empire, one religion".. Constantinople is generally considered the "cradle of Orthodox Role of Christianity in civilization, Christian civilization". The imperial role in the affairs of the Church never developed into a fixed, legally defined system.. Additionally, the decline of Rome and the internal dissension in the other Eastern patriarchates, made the Church of Constantinople, between the 6th and 11th centuries, the richest and most influential centre of Christendom..

points out: Byzantine monasticism especially came to be an "ever-present feature" of the empire, with monasteries becoming "powerful landowners and a voice to be listened to in imperial politics". The official state Christian doctrine was determined by the first seven ecumenical councils, and it was then the emperor's duty to impose it on his subjects. An imperial decree of 388, which was later incorporated into the ''Codex Justinianeus'', orders the population of the empire "to assume the name of Catholic Christians", and regards all those who will not abide by the law as "mad and foolish persons"; as followers of "heretical dogmas". Despite imperial decrees and the stringent stance of the state church of the Roman Empire, state church, which came to be known as the Eastern Orthodox Church or Eastern Christianity, the Eastern Orthodox Church never represented all Christians in Byzantium. Mango believes that in the early stages of the empire, the "mad and foolish persons"—those labelled "heretics" by the state church—were the majority of the population.. Besides the paganism, pagans who existed until the end of the 6th century, and the History of the Jews in the Byzantine Empire, Jews, there were many followers—sometimes even emperors—of various Christian doctrines, such as Nestorianism, Monophysitism, Arianism, and Paulicianism, whose teachings were in some opposition to the main theological doctrine as determined by the Ecumenical Councils. Another division among Christians occurred, when Leo III ordered the destruction of icons throughout the Empire. This led to a significant religious crisis, which ended in the mid-9th century with the restoration of icons. During the same period, a new wave of pagans emerged in the Balkans, originating mainly from Slavic people. These were gradually Christianization, Christianised, and by Byzantium's late stages, Eastern Orthodoxy represented most Christians and, in general, most people in what remained of the empire.. Jews were a significant minority in the Byzantine state throughout its history, and according to Roman law, they constituted a legally recognised religious group. In the early Byzantine period they were generally tolerated, but then periods of tensions and persecutions ensued. In any case, after the Arab conquests the majority of Jews found themselves outside the empire; those left inside the Byzantine borders apparently lived in relative peace from the 10th century onwards..


The arts


Art

Surviving Byzantine art is mostly religious and with exceptions at certain periods is highly conventionalised, following traditional models that translate carefully controlled church theology into artistic terms. Painting in fresco, illuminated manuscripts and on wood panel and, especially in earlier periods, mosaic were the main media, and figurative sculpture very rare except for small ivory carving, carved ivories. Manuscript painting preserved to the end some of the classical realist tradition that was missing in larger works. Byzantine art was highly prestigious and sought-after in Western Europe, where it maintained a continuous influence on medieval art until near the end of the period. This was especially so in Italy, where Byzantine styles persisted in modified form through the 12th century, and became formative influences on Italian Renaissance art. But few incoming influences affected the Byzantine style. With the expansion of the Eastern Orthodox Church, Byzantine forms and styles spread throughout the Orthodox world and beyond. Influences from Byzantine architecture, particularly in religious buildings, can be found in diverse regions from Egypt and Arabia to Neo-Byzantine architecture in the Russian Empire, Russia and Romania. Byzantine architecture is known for the use of Dome, domes, and pendentive architecture was invented in the Byzantine Empire. It also often featured marble columns, coffered ceilings and sumptuous decoration, including the extensive use of

s with golden backgrounds. The building material used by Byzantine architects was no longer marble, which was very appreciated by the Ancient Greeks. They used mostly stone and brick, and also thin alabaster sheets for windows. Mosaics were used to cover brick walls, and any other surface where fresco wouldn't resist. Good examples of mosaics from the proto-Byzantine era are in Hagios Demetrios in

Greco-Roman temples and Byzantine churches differ substantially in terms of their exterior and interior aspect. In Antiquity, the exterior was the most important part of the temple, because in the interior, where the cult statue of the deity to whom the temple was built was kept, only the priest had access. The ceremonies here held outside, and what the worshipers view was the facade of the temple, consisting of columns, with an entablature and two pediments. Meanwhile, Christian liturgies were held in the interior of the churches, the exterior usually having little to no ornamentation.

Literature

In Byzantine literature, three different cultural elements are recognised: the Greek literature, Greek, the Christian, and the Ancient Near East, Oriental. Byzantine literature is often classified in five groups: historians and annalists; encyclopaedists (Photios I of Constantinople, Patriarch Photios, Michael Psellos, Michael Psellus, and Michael Choniates are regarded as the greatest encyclopaedists of Byzantium) and essayists; writers of secular poetry (the only genuine heroic epic of the Byzantines is the ''Digenes Akritas, Digenis Acritas);'' ecclesiastical and theological literature; and popular poetry.. Of the 2,000 to 3,000 volumes of Byzantine literature that survive, only 330 consist of secular poetry, history, science and pseudo-science. While the most flourishing period of the secular literature of Byzantium runs from the 9th to the 12th century, its religious literature (sermons, liturgical books and poetry, theology, devotional treatises, etc.) developed much earlier with

being its most prominent representative.


Music

The ecclesiastical forms of Byzantine music—composed to Greek texts as ceremonial, festival, or church music—are today the most well-known forms. Ecclesiastical chants were a fundamental part of this genre. Greek and foreign historians agree that the ecclesiastical tones and in general the whole system of Byzantine music is closely related to the Music of ancient Greece, ancient Greek system. It remains the oldest genre of extant music, of which the manner of performance and (with increasing accuracy from the 5th century onwards) the names of the composers, and sometimes the particulars of each musical work's circumstances, are known. The 9th-century Persian geographer Ibn Khordadbeh, in his lexicographical discussion of instruments, cited the Byzantine lyra, lyra (lūrā) as the typical instrument of the Byzantines along with the ''urghun'' (organ), ''shilyani'' (probably a type of harp or lyre) and the ''salandj'' (probably a Bagpipes, bagpipe).. The first of these, the early bowed stringed instrument known as the Byzantine lyra, came to be called the ''lira da braccio'', in Venice, where it is considered by many to have been the predecessor of the contemporary violin, which later flourished there. The bowed "lyra" is still played in former Byzantine regions, where it is known as the Classical kemençe, Politiki lyra (, i.e. Constantinople) in Greece, the Calabrian lira in southern Italy, and the lijerica in Dalmatia. The water organ originated in the Hellenistic world and was used in the Hippodrome during races.Douglas Earl Bush, Richard Kassel editors, ''The Organ: An Encyclopedia'' Routledge. 2006.

requested a similar organ for his chapel in Aachen in 812, beginning its establishment in Western church music. The aulos was a double-reeded woodwind like the modern oboe or Armenian duduk. Other forms include the ''plagiaulos'' (''πλαγίαυλος'', from ''πλάγιος'' "sideways"), which resembled the flute, and the ''askaulos'' (ἀσκός ''askos'' – wineskin), a bagpipe. Bagpipes, also known as ''dankiyo'' (from ancient Greek: angion (Τὸ ἀγγεῖον) "the container"), had been played even in Roman times and continued to be played throughout the empire's former realms through to the present. (See Balkan Gaida, Greek Tsampouna, Pontic Greek, Pontic Tulum (bagpipe), Tulum, Cretan Askomandoura, Armenian Parkapzuk, and Romanian Cimpoi.) The modern descendant of the aulos is the Greek Zurna, Zourna. Other instruments used in Byzantine Music were Qanun (instrument), Kanonaki, Oud, Laouto, Santouri, Tambouras, Seistron (defi tambourine), Toubeleki and Daouli. Some claim that Lavta may have been invented by the Byzantines before the arrival of the Turks.


Cuisine

Byzantine culture was initially the same as Late Greco-Roman, but over the following millennium of the empire's existence it slowly changed into something more similar to modern Balkan and Anatolian culture. The cuisine still relied heavily on the Greco-Roman fish-sauce condiment garum, garos, but it also contained foods still familiar today, such as the cured meat pastirma (known as "paston" in Byzantine Greek), baklava (known as Placenta cake, koptoplakous κοπτοπλακοῦς), tiropita (known as plakountas tetyromenous or tyritas plakountas), and the famed medieval sweet wines (Malvasia from

, Commandaria and the eponymous Rumney wine). Retsina, wine flavoured with pine resin, was also drunk, as it still is in Greece today, producing similar reactions from unfamiliar visitors; "To add to our calamity the Greek wine, on account of being mixed with pitch, resin, and plaster was to us undrinkable," complained Liutprand of Cremona, who was the ambassador sent to Constantinople in 968 by the German Holy Roman Emperor Otto I. The garos fish sauce condiment was also not much appreciated by the unaccustomed; Liutprand of Cremona described being served food covered in an "exceedingly bad fish liquor." The Byzantines also used a soy sauce-like condiment, murri (condiment), murri, a fermented barley sauce, which, like soy sauce, provided umami flavouring to their dishes.


Flags and insignia

For most of its history, the Byzantine Empire did not know or use heraldry in the West European sense. Various emblems (, ''sēmeia''; sing. σημείον, ''sēmeion'') were used in official occasions and for military purposes, such as banners or shields displaying various motifs such as the cross or the ''labarum''. The use of the cross and images of Jesus, Christ, the Mary, mother of Jesus, Virgin Mary and various saints is also sigillography, attested on seals of officials, but these were personal rather than family emblems.


Language

Apart from the Imperial court, administration and military, the primary language used in the eastern Roman provinces even before the decline of the Western Empire was Greek, having been spoken in the region for centuries before Latin. Following Rome's conquest of the east its 'Pax Romana', inclusionist political practices and development of public infrastructure, facilitated the further spreading and entrenchment of the Greek language in the east. Indeed, early on in the life of the Roman Empire, Greek had become the common language of the Church, the language of scholarship and the arts, and to a large degree the ''lingua franca'' for trade between provinces and with other nations. Greek for a time became Diglossia, diglossic with the spoken language, known as Koine Greek, Koine (eventually evolving into Demotic Greek), used alongside an older written form (Attic Greek) until Koine Greek, Koine won out as the spoken and written standard. The Emperor
Diocletian Diocletian (; la, Gaius Aurelius Valerius Diocletianus, grc, Διοκλητιανός, Diokletianós; c. 242/245 – 311/312), nicknamed ''Iovius'', was Roman emperor from 284 until his abdication in 305. He was born Gaius Valerius Diocles ...
sought to renew the authority of Latin, making it the official language of the Roman administration also in the East, and the Greek expression ἡ κρατοῦσα διάλεκτος ''(hē kratousa dialektos)'' attests to the status of Latin as "the language of power." In the early 5th century, Greek gained equal status with Latin as the official language in the East, and emperors gradually began to legislate in Greek rather than Latin starting with the reign of Leo I the Thracian in the 460s.The Inheritance of Rome, Chris Wickham, Penguin Books Ltd. 2009, . p. 90. The last Eastern emperor to stress the importance of Latin was Justinian I, whose ''Corpus Juris Civilis'' was written almost entirely in Latin. He may also have been the last native Latin-speaking emperor. The use of Latin as the language of administration persisted for centuries, though it was increasingly replaced by Greek. Scholarly Latin rapidly fell into disuse among the educated classes although the language continued to be at least a ceremonial part of the Empire's culture for some time.; Additionally, Latin remained a minority language in the empire, mainly on the Italian peninsula, along the Dalmatian coast and in the Balkans (specially in mountainous areas away from the coast), eventually developing into various Romance languages like Dalmatian language, Dalmatian or Romanian language, Romanian. Many other languages existed in the multi-ethnic empire, and some of these were given limited official status in their provinces at various times. Notably, by the beginning of the Middle Ages, Syriac language, Syriac had become more widely used by the educated classes in the far eastern provinces.; ; . Similarly Coptic language, Coptic, Armenian language, Armenian, and Georgian language, Georgian became significant among the educated in their provinces. Later foreign contacts made Old Church Slavonic, Old Church Slavic, Middle Persian, and Classical Arabic, Arabic important in the empire and its sphere of influence. There was a revival of Latin studies in the 10th century for the same reason and by the 11th century knowledge of Latin was no longer unusual at Constantinople. There was widespread use of the Armenian and various Slavic languages, which became more pronounced in the border regions of the empire. Aside from these languages, since Constantinople was a prime trading centre in the History of the Mediterranean region, Mediterranean region and beyond, virtually every known language of the Middle Ages was spoken in the empire at some time, even Chinese language, Chinese. As the empire entered its final decline, its citizens became more culturally homogeneous and the Greek language became integral to their identity and religion.


Recreation

Byzantines were avid players of tabula (game), tavli (Byzantine Greek: τάβλη), a game known in English as backgammon, which is still popular in former Byzantine realms and still known by the name tavli in Greece. Byzantine nobles were devoted to horsemanship, particularly Tzykanisterion, tzykanion, now known as polo. The game came from Sassanid Persia, and a Tzykanisterion (stadium for playing the game) was built by Theodosius II inside the Great Palace of Constantinople. Emperor Basil I excelled at it; Emperor Alexander died from exhaustion while playing, Emperor Alexios I Komnenos was injured while playing with Tatikios, and John I of Trebizond died from a fatal injury during a game. Aside from Constantinople and Trebizond, other Byzantine cities also featured ''tzykanisteria'', most notably Sparta, Ephesus, and Athens, an indication of a thriving urban aristocracy. The game was introduced to the West by crusaders, who developed a taste for it particularly during the pro-Western reign of Emperor Manuel I Komnenos. Chariot races were popular and held at hippodromes across the empire. There were initially four major factions in chariot racing, differentiated by the colour of the uniform in which they competed; the colours were also Byzantine dress, worn by their supporters. These were the Blues (''Veneti''), the Greens (''Prasini''), the Reds (''Russati''), and the Whites (''Albati''), although by the Byzantine era the only teams with any influence were the Blues and Greens. Emperor Justinian I was a supporter of the Blues.


Women

The position of women in the Byzantine Empire essentially represents the position of women in ancient Rome transformed by the introduction of Christianity, with certain rights and customs being lost and replaced, while others were allowed to remain. There were individual Byzantine women famed for their educational accomplishments. However, the general view of women's education was that it was sufficient for a girl to learn domestic duties and to study the lives of the Christian saints and memorize psalms,Guglielmo Cavallo:
The Byzantines
''
and to learn to read so that she could study Bible scriptures—although literacy in women was sometimes discouraged because it was believed it could encourage vice.Paul Stephenson:
The Byzantine World
''
The Roman right to divorce was gradually erased after the introduction of Christianity and replaced with legal separation and annulment. Marriage was regarded as the ideal state for a woman, and only convent life was seen as a legitimate alternative. Within marriage, sexual activity was regarded only as a means of reproduction. Women had the right to appear before court, but her testimony was not regarded as equal to that of a man and could be contradicted based on her sex if put against that of a man. From the 6th century there was a growing ideal of Sex segregation, gender segregation, which dictated that women should wear veilsMarcus Louis Rautman:
Daily Life in the Byzantine Empire
''
and only be seen in public when attending church,Lynda Garland:
Byzantine Women: Varieties of Experience 800–1200
''
and while the ideal was never fully enforced, it influenced society. The laws of Emperor Justinian I made it legal for a man to divorce his wife for attending public premises such as theatres or public baths without his permission,Jonathan Harris:
Constantinople: Capital of Byzantium
''
and Emperor Leo VI banned women from witnessing business contracts with the argument that it caused them to come in contact with men. In Constantinople upper-class women were increasingly expected to keep to a special women's section (''gynaikonitis''), and by the 8th century it was described as unacceptable for unmarried daughters to meet unrelated men. While imperial women and their ladies appeared in public alongside men, women and men at the imperial court attended royal banquets separately until the rise of the Komnenos dynasty in the 12th century. Eastern Roman and later Byzantine women retained the Roman woman's right to inherit, own and manage their property and signs contracts, rights which were far superior to the rights of married women in Medieval Catholic Western Europe, as these rights included both married women as well as unmarried women and widows. Women's legal right to handle their own money made it possible for rich women to engage in business, however women who actively had to find a profession to support themselves normally worked as domestics or in domestic fields such as the food or textile industry. Women could work as medical physicians and attendants of women patients and visitors at hospitals and public baths with government support. After the introduction of Christianity, women could no longer become priestesses, but it became common for women to found and manage nunneries, which functioned as schools for girls as well as asylums, poor houses, hospitals, prisons and retirement homes for women, and many Byzantine women practised social work as lay sisters and deaconesses.


Economy

The Byzantine economy was among the most advanced in Europe and the Mediterranean for many centuries. Europe, in particular, could not match Byzantine economic strength until late in the Middle Ages. Constantinople operated as a prime hub in a trading network that at various times extended across nearly all of Eurasia and North Africa, in particular as the primary western terminus of the famous Silk Road. Until the first half of the 6th century and in sharp contrast with the decaying West, the Byzantine economy was flourishing and resilient. The Plague of Justinian and the Arab conquests represented a substantial reversal of fortunes contributing to a period of stagnation and decline. Isaurian reforms and Constantine V's repopulation, public works and tax measures marked the beginning of a revival that continued until 1204, despite territorial contraction. From the 10th century until the end of the 12th, the Byzantine Empire projected an image of luxury and travellers were impressed by the wealth accumulated in the capital.; . The Fourth Crusade resulted in the disruption of Byzantine manufacturing and the commercial dominance of the Western Europeans in the eastern Mediterranean, events that amounted to an economic catastrophe for the empire. The Palaiologos, Palaiologoi tried to revive the economy, but the late Byzantine state did not gain full control of either the foreign or domestic economic forces. Gradually, Constantinople also lost its influence on the modalities of trade and the price mechanisms, and its control over the outflow of precious metals and, according to some scholars, even over the minting of coins.. One of the economic foundations of Byzantium was trade, fostered by the maritime character of the empire. Textiles must have been by far the most important item of export; silks were certainly imported into Egypt and appeared also in Bulgaria, and the West.; . The state strictly controlled both the internal and the international trade, and retained the monopoly of issuing Byzantine coinage, coinage, maintaining a durable and flexible monetary system adaptable to trade needs.; . The government attempted to exercise formal control over interest rates and set the parameters for the activity of the guilds and corporations, in which it had a special interest. The emperor and his officials intervened at times of crisis to ensure the provisioning of the capital, and to keep down the price of cereals. Finally, the government often collected part of the surplus through taxation, and put it back into circulation, through redistribution in the form of salaries to state officials, or in the form of investment in public works.


Legacy

Byzantium has been often identified with absolutism, orthodox spirituality, orientalism and exoticism, while the terms "Byzantine" and "Byzantinism" have been used as bywords for decadence, complex bureaucracy, and repression. Both Eastern and Western European authors have often perceived Byzantium as a body of religious, political, and philosophical ideas contrary to those of the West. Even in History of modern Greece, 19th-century Greece, the focus was mainly on the classical past, while Byzantine tradition had been associated with negative connotations.. This traditional approach towards Byzantium has been partially or wholly disputed and revised by modern studies, which focus on the positive aspects of Byzantine culture and legacy. Averil Cameron regards as undeniable the Byzantine contribution to the formation of medieval Europe, and both Cameron and Obolensky recognise the major role of Byzantium in shaping Orthodoxy, which in turn occupies a central position in the history, societies and culture of Greece, Romania, Bulgaria, Russia, Georgia, Serbia and other countries. The Byzantines also preserved and copied classical manuscripts, and they are thus regarded as transmitters of classical knowledge, as important contributors to modern European civilisation, and as precursors of both Renaissance humanism and Slavic-Orthodox culture. Some scholars focused on the positive aspects of Byzantine culture and legacy, French historian Charles Diehl describes the Byzantine Empire by saying: As the only stable long-term state in Europe during the Middle Ages, Byzantium isolated Western Europe from newly emerging forces to the East. Constantly under attack, it distanced Western Europe from Persians, Arabs, Seljuk Turks, and for a time, the Ottomans. From a different perspective, since the 7th century, the evolution and constant reshaping of the Byzantine state were directly related to the respective progress of Islam.. Following the conquest of Constantinople by the Ottoman Turks in 1453, Sultan Mehmed II took the title "''Kaysar-i Rûm''" (the Ottoman Turkish equivalent of Caesar (title), Caesar of Rome), since he was determined to make the Ottoman Empire the heir of the Eastern Roman Empire.; .
