Late antiquity is the time of transition from classical antiquity to the Middle Ages, generally spanning the 3rd–7th century in Europe and adjacent areas bordering the Mediterranean Basin. The popularization of this periodization in English has generally been credited to historian Peter Brown, after the publication of his seminal work The World of Late Antiquity (1971). Precise boundaries for the period are a continuing matter of debate, but Brown proposes a period between the 3rd and 8th centuries AD. Generally, it can be thought of as from the end of the Roman Empire's Crisis of the Third Century (235–284) to the early Muslim conquests (622–750), or as roughly contemporary with the Sasanian Empire (224–651). In the West its end was earlier, with the start of the Early Middle Ages typically placed in the 6th century, or earlier on the edges of the Western Roman Empire.
The Roman Empire underwent considerable social, cultural and organizational changes starting with the reign of Diocletian, who began the custom of splitting the Empire into Eastern and Western portions ruled by multiple emperors simultaneously. The Sasanian Empire supplanted the Parthian Empire and began a new phase of the Roman–Persian Wars, the Roman–Sasanian Wars. The divisions between the Greek East and Latin West became more pronounced. The Diocletianic Persecution of Christians in the early 4th century was ended by Galerius and under Constantine the Great, Christianity was made legal in the Empire. The 4th century Christianization of the Roman Empire was extended by the conversions of Tiridates the Great of Armenia, Mirian III of Iberia and Ezana of Axum, who later invaded and ended the Kingdom of Kush. During the late 4th century reign of Theodosius I, Nicene Christianity was proclaimed the state church of the Roman Empire.
The city of Constantinople became the permanent imperial residence in the East by the 5th century and superseded Rome as the largest city in the Late Roman Empire and the Mediterranean Basin. The longest Roman aqueduct system, the 250 km (160 mi)-long Aqueduct of Valens was constructed to supply it with water, and the tallest Roman triumphal columns were erected there.
Migrations of Germanic, Hunnic, and Slavic tribes disrupted Roman rule from the late 4th century onwards, culminating first in the Sack of Rome by the Visigoths in 410 and subsequent Sack of Rome by the Vandals in 455, part of the eventual collapse of the Empire in the West itself by 476. The Western Empire was replaced by the so-called barbarian kingdoms, with the Arian Christian Ostrogothic Kingdom ruling Rome from Ravenna. The resultant cultural fusion of Greco-Roman, Germanic, and Christian traditions formed the foundations of the subsequent culture of Europe.
In the 6th century, Roman imperial rule continued in the East, and the Byzantine-Sasanian wars continued. The campaigns of Justinian the Great led to the fall of the Ostrogothic and Vandal Kingdoms, and their reincorporation into the Empire, when the city of Rome and much of Italy and North Africa returned to imperial control. Though most of Italy was soon part of the Kingdom of the Lombards, the Roman Exarchate of Ravenna endured, ensuring the so-called Byzantine Papacy. Justinian constructed the Hagia Sophia, a great example of Byzantine architecture, and the first outbreak of the centuries-long first plague pandemic took place. At Ctesiphon, the Sasanians completed the Taq Kasra, the colossal iwan of which is the largest single-span vault of unreinforced brickwork in the world and the triumph of Sasanian architecture.
The middle of the 6th century was characterized by extreme climate events (the volcanic winter of 535-536 and the Late Antique Little Ice Age) and a disastrous pandemic (the Plague of Justinian in 541). The effects of these events in the social and political life are still under discussion.
In the 7th century the disastrous Byzantine–Sasanian War of 602–628 and the campaigns of Khosrow II and Heraclius facilitated the emergence of Islam in the Arabian Peninsula during the lifetime of Muhammad. Subsequent Muslim conquest of the Levant and Persia overthrew the Sasanian Empire and permanently wrested two thirds of the Eastern Roman Empire's territory from Roman control, forming the Rashidun Caliphate.
The Byzantine Empire under the Heraclian dynasty began the middle Byzantine period, and together with the establishment of the later 7th century Umayyad Caliphate, generally marks the end of late antiquity.
The term Spätantike, literally "late antiquity", has been used by German-speaking historians since its popularization by Alois Riegl in the early 20th century.  It was given currency in English partly by the writings of Peter Brown, whose survey The World of Late Antiquity (1971) revised the Gibbon view of a stale and ossified Classical culture, in favour of a vibrant time of renewals and beginnings, and whose The Making of Late Antiquity offered a new paradigm of understanding the changes in Western culture of the time in order to confront Sir Richard Southern's The Making of the Middle Ages. 
The continuities between the later Roman Empire,  as it was reorganized by Diocletian (r. 284–305), and the Early Middle Ages are stressed by writers who wish to emphasize that the seeds of medieval culture were already developing in the Christianized empire, and that they continued to do so in the Eastern Roman Empire or Byzantine Empire at least until the coming of Islam. Concurrently, some migrating Germanic tribes such as the Ostrogoths and Visigoths saw themselves as perpetuating the "Roman" tradition. While the usage "Late Antiquity" suggests that the social and cultural priorities of Classical Antiquity endured throughout Europe into the Middle Ages, the usage of "Early Middle Ages" or "Early Byzantine" emphasizes a break with the classical past, and the term "Migration Period" tends to de-emphasize the disruptions in the former Western Roman Empire caused by the creation of Germanic kingdoms within her borders beginning with the foedus with the Goths in Aquitania in 418. 
The general decline of population, technological knowledge and standards of living in Europe during this period became the archetypal example of societal collapse for writers from the Renaissance. As a result of this decline, and the relative scarcity of historical records from Europe in particular, the period from roughly the early fifth century until the Carolingian Renaissance (or later still) was referred to as the "Dark Ages". This term has mostly been abandoned as a name for a historiographical epoch, being replaced by "Late Antiquity" in the periodization of the late West Roman Empire, the early Byzantine empire and the Early Middle Ages. 
One of the most important transformations in Late Antiquity was the formation and evolution of the Abrahamic religions: Christianity, Rabbinic Judaism and, eventually, Islam.
A milestone in the spread of Christianity was the conversion of Emperor Constantine the Great (r. 306–337) in 312, as claimed by his Christian panegyrist Eusebius of Caesarea, although the sincerity of his conversion is debated.   Constantine confirmed the legalization of the religion through the so-called Edict of Milan in 313, jointly issued with his rival in the East, Licinius (r. 308–324). By the late 4th century, Emperor Theodosius the Great had made Christianity the State religion, thereby transforming the Classical Roman world, which Peter Brown characterized as "rustling with the presence of many divine spirits." 
Constantine I was a key figure in many important events in Christian history, as he convened and attended the first ecumenical council of bishops at Nicaea in 325, subsidized the building of churches and sanctuaries such as the Church of the Holy Sepulchre in Jerusalem, and involved himself in questions such as the timing of Christ's resurrection and its relation to the Passover. 
The birth of Christian monasticism in the deserts of Egypt in the 3rd century, which initially operated outside the episcopal authority of the Church, would become so successful that by the 8th century it penetrated the Church and became the primary Christian practice. Monasticism was not the only new Christian movement to appear in late antiquity, although it had perhaps the greatest influence. Other movements notable for their unconventional practices include the Grazers, holy men who ate only grass and chained themselves up;  the Holy Fool movement, in which acting like a fool was considered more divine than folly; and the Stylites movement, where one practitioner lived atop a 50-foot pole for 40 years.
Late Antiquity marks the decline of Roman state religion, circumscribed in degrees by edicts likely inspired by Christian advisors such as Eusebius to 4th-century emperors, and a period of dynamic religious experimentation and spirituality with many syncretic sects, some formed centuries earlier, such as Gnosticism or Neoplatonism and the Chaldaean oracles, some novel, such as hermeticism. Culminating in the reforms advocated by Apollonius of Tyana being adopted by Aurelian and formulated by Flavius Claudius Julianus to create an organized but short-lived pagan state religion that ensured its underground survival into the Byzantine age and beyond. 
Mahāyāna Buddhism developed in India and along the Silk Road in Central Asia, while Manichaeism, a Dualist faith, arose in Mesopotamia and spread both East and West, for a time contending with Christianity in the Roman Empire.
Many of the new religions relied on the emergence of the parchment codex (bound book) over the papyrus volumen (scroll), the former allowing for quicker access to key materials and easier portability than the fragile scroll, thus fueling the rise of synoptic exegesis, papyrology. Notable in this regard is the topic of the Fifty Bibles of Constantine.
Within the recently legitimized Christian community of the 4th century, a division could be more distinctly seen between the laity and an increasingly celibate male leadership.  These men presented themselves as removed from the traditional Roman motivations of public and private life marked by pride, ambition and kinship solidarity, and differing from the married pagan leadership. Unlike later strictures on priestly celibacy, celibacy in Late Antique Christianity sometimes took the form of abstinence from sexual relations after marriage, and it came to be the expected norm for urban clergy. Celibate and detached, the upper clergy became an elite equal in prestige to urban notables, the potentes or dynatoi (Brown (1987) p. 270).
Islam appeared in the 7th century, spurring Arab armies to invade the Eastern Roman Empire and the Sassanian Empire of Persia, destroying the latter. After conquering all of North Africa and Visigothic Spain, the Islamic invasion was halted by Charles Martel at the Battle of Tours in modern France. 
On the rise of Islam, two main theses prevail. On the one hand, there is the traditional view, as espoused by most historians prior to the second half of the twentieth century (and after) and by Muslim scholars. This view, the so-called "out of Arabia"-thesis, holds that Islam as a phenomenon was a new, alien element in the late antique world. Related to this is the Pirenne Thesis, according to which the Arab invasions marked—through conquest and the disruption of Mediterranean trade routes—the cataclysmic end of Late Antiquity and the beginning of the Middle Ages.
On the other hand, there is a more recent thesis, associated with scholars in the tradition of Peter Brown, in which Islam is seen to be a product of the Late Antique world, not foreign to it. This school suggests that its origin within the shared cultural horizon of the late antique world explains the character of Islam and its development. Such historians point to similarities with other late antique religions and philosophies—especially Christianity—in the prominent role and manifestations of piety in Islam, in Islamic asceticism and the role of "holy persons", in the pattern of universalist, homogeneous monotheism tied to worldly and military power, in early Islamic engagement with Greek schools of thought, in the apocalypticism of Islamic theology and in the way the Quran seems to react to contemporary religious and cultural issues shared by the late antique world at large. Further indication that Arabia (and thus the environment in which Islam first developed) was a part of the late antique world is found in the close economic and military relations between Arabia, the Byzantine Empire and the Sassanian Empire. 
The Late Antique period also saw a wholesale transformation of the political and social basis of life in and around the Roman Empire.
The Roman citizen elite in the 2nd and 3rd centuries, under the pressure of taxation and the ruinous cost of presenting spectacular public entertainments in the traditional cursus honorum , had found under the Antonines that security could only be obtained by combining their established roles in the local town with new ones as servants and representatives of a distant Emperor and his traveling court. After Constantine centralized the government in his new capital of Constantinople (dedicated in 330), the Late Antique upper classes were divided among those who had access to the far-away centralized administration (in concert with the great landowners), and those who did not—though they were well-born and thoroughly educated, a classical education and the election by the Senate to magistracies was no longer the path to success. Room at the top of Late Antique society was more bureaucratic and involved increasingly intricate channels of access to the emperor: the plain toga that had identified all members of the Republican senatorial class was replaced with the silk court vestments and jewelry associated with Byzantine imperial iconography.  Also indicative of the times is the fact that the imperial cabinet of advisors came to be known as the consistorium , or those who would stand in courtly attendance upon their seated emperor, as distinct from the informal set of friends and advisors surrounding the Augustus .
The later Roman Empire was in a sense a network of cities. Archaeology now supplements literary sources to document the transformation followed by collapse of cities in the Mediterranean basin. Two diagnostic symptoms of decline—or as many historians prefer, 'transformation'—are subdivision, particularly of expansive formal spaces in both the domus and the public basilica, and encroachment, in which artisans' shops invade the public thoroughfare, a transformation that was to result in the souk (marketplace).  Burials within the urban precincts mark another stage in dissolution of traditional urbanistic discipline, overpowered by the attraction of saintly shrines and relics. In Roman Britain, the typical 4th- and 5th-century layer of dark earth within cities seems to be a result of increased gardening in formerly urban spaces. 
The city of Rome went from a population of 800,000 in the beginning of the period to a population of 30,000 by the end of the period, the most precipitous drop coming with the breaking of the aqueducts during the Gothic War. A similar though less marked decline in urban population occurred later in Constantinople, which was gaining population until the outbreak of the Plague of Justinian in 541. In Europe there was also a general decline in urban populations. As a whole, the period of late antiquity was accompanied by an overall population decline in almost all Europe, and a reversion to more of a subsistence economy. Long-distance markets disappeared, and there was a reversion to a greater degree of local production and consumption, rather than webs of commerce and specialized production. 
Concurrently, the continuity of the Eastern Roman Empire at Constantinople meant that the turning-point for the Greek East came later, in the 7th century, as the Eastern Roman, or Byzantine Empire centered around the Balkans, North Africa (Egypt and Carthage), and Asia Minor. The degree and extent of discontinuity in the smaller cities of the Greek East is a moot subject among historians.  The urban continuity of Constantinople is the outstanding example of the Mediterranean world; of the two great cities of lesser rank, Antioch was devastated by the Persian sack of 540, followed by the plague of Justinian (542 onwards) and completed by earthquake, while Alexandria survived its Islamic transformation, to suffer incremental decline in favour of Cairo in the medieval period.
Justinian rebuilt his birthplace in Illyricum, as Justiniana Prima, more in a gesture of imperium than out of an urbanistic necessity; another "city", was reputed to have been founded, according to Procopius' panegyric on Justinian's buildings,  precisely at the spot where the general Belisarius touched shore in North Africa: the miraculous spring that gushed forth to give them water and the rural population that straightway abandoned their ploughshares for civilised life within the new walls, lend a certain taste of unreality to the project.
In mainland Greece, the inhabitants of Sparta, Argos and Corinth abandoned their cities for fortified sites in nearby high places; the fortified heights of Acrocorinth are typical of Byzantine urban sites in Greece. In Italy, populations that had clustered within reach of Roman roads began to withdraw from them, as potential avenues of intrusion, and to rebuild in typically constricted fashion round an isolated fortified promontory, or rocca ; Cameron notes similar movement of populations in the Balkans, 'where inhabited centres contracted and regrouped around a defensible acropolis, or were abandoned in favour of such positions elsewhere." 
In the western Mediterranean, the only new cities known to be founded in Europe between the 5th and 8th centuries  were the four or five Visigothic "victory cities".  Reccopolis in the province of Guadalajara is one: the others were Victoriacum, founded by Leovigild, which may survive as the city of Vitoria, though a 12th-century (re)foundation for this city is given in contemporary sources; Lugo id est Luceo in the Asturias, referred to by Isidore of Seville, and Ologicus (perhaps Ologitis), founded using Basque labour in 621 by Suinthila as a fortification against the Basques, modern Olite. All of these cities were founded for military purposes and at least Reccopolis, Victoriacum, and Ologicus in celebration of victory. A possible fifth Visigothic foundation is Baiyara (perhaps modern Montoro), mentioned as founded by Reccared in the 15th-century geographical account, Kitab al-Rawd al-Mitar .  The arrival of a highly urbanized Islamic culture in the decade following 711 ensured the survival of cities in the Hispaniae into the Middle Ages.
Beyond the Mediterranean world, the cities of Gaul withdrew within a constricted line of defense around a citadel. Former imperial capitals such as Cologne and Trier lived on in diminished form as administrative centres of the Franks. In Britain, where the break with Late Antiquity comes earliest in the 5th and the 6th century, most towns and cities had been in rapid decline during the 4th century during a time of prosperity until the last decades of the century, well before the withdrawal of Roman governors and garrisons; historians emphasizing urban continuities with the Anglo-Saxon period depend largely on the post-Roman survival of Roman toponymy. Aside from a mere handful of its continuously inhabited sites, like York and London and possibly Canterbury, however, the rapidity and thoroughness with which its urban life collapsed with the dissolution of centralized bureaucracy calls into question the extent to which Roman Britain had ever become authentically urbanized: "in Roman Britain towns appeared a shade exotic," observes H. R. Loyn, "owing their reason for being more to the military and administrative needs of Rome than to any economic virtue".  The other institutional power centre, the Roman villa, did not survive in Britain either.  Gildas lamented the destruction of the twenty-eight cities of Britain; though not all in his list can be identified with known Roman sites, Loyn finds no reason to doubt the essential truth of his statement. 
Classical Antiquity can generally be defined as an age of cities; the Greek polis and Roman municipium were locally organised, self-governing bodies of citizens governed by written constitutions. When Rome came to dominate the known world, local initiative and control were gradually subsumed by the ever-growing Imperial bureaucracy; by the Crisis of the Third Century the military, political and economic demands made by the Empire had crushed the civic spirit, and service in local government came to be an onerous duty, often imposed as punishment.[ citation needed ] Harassed urban dwellers fled to the walled estates of the wealthy to avoid taxes, military service, famine and disease. In the Western Roman Empire especially, many cities destroyed by invasion or civil war in the 3rd century could not be rebuilt. Plague and famine hit the urban class in greater proportion, and thus the people who knew how to keep civic services running. Perhaps the greatest blow came in the wake of the extreme weather events of 535–536 and subsequent Plague of Justinian, when the remaining trade networks ensured the Plague spread to the remaining commercial cities. The impact of this outbreak of plague has recently been disputed.   The end of Classical Antiquity is the end of the Polis model, and the general decline of cities is a defining feature of Late Antiquity.
In the cities the strained economies of Roman over-expansion arrested growth. Almost all new public building in Late Antiquity came directly or indirectly from the emperors or imperial officials. Attempts were made to maintain what was already there. The supply of free grain and oil to 20% of the population of Rome remained intact the last decades of the 5th century. It was once thought that the elite and rich had withdrawn to the private luxuries of their numerous villas and town houses. Scholarly opinion has revised this. They monopolized the higher offices in the imperial administration, but they were removed from military command by the late 3rd century. Their focus turned to preserving their vast wealth rather than fighting for it.
The basilica, which had functioned as a law court or for imperial reception of foreign dignitaries, became the primary public building in the 4th century. Due to the stress on civic finances, cities spent money on walls, maintaining baths and markets at the expense of amphitheaters, temples, libraries, porticoes, gymnasia, concert and lecture halls, theaters and other amenities of public life. In any case as Christianity took over many of these building which were associated with pagan cults were neglected in favor of building churches and donating to the poor. The Christian basilica was copied from the civic structure with variations. The bishop took the chair in the apse reserved in secular structures for the magistrate—or the Emperor himself—as the representative here and now of Christ Pantocrator, the Ruler of All, his characteristic Late Antique icon. These ecclesiastical basilicas (e.g., St. John Lateran and St. Peter's in Rome) were themselves outdone by Justinian's Hagia Sophia, a staggering display of later Roman/Byzantine power and architectural taste, though the building is not architecturally a basilica. In the former Western Roman Empire almost no great buildings were constructed from the 5th century. A most outstanding example is the Basilica of San Vitale in Ravenna constructed circa 530 at a cost of 26,000 gold solidi or 360 Roman pounds of gold.
City life in the East, though negatively affected by the plague in the 6th–7th centuries, finally collapsed due to Slavic invasions in the Balkans and Persian destructions in Anatolia in the 620s. City life continued in Syria, Jordan and Palestine into the 8th. In the later 6th century street construction was still undertaken in Caesarea Maritima in Palestine,  and Edessa was able to deflect Chosroes I with massive payments in gold in 540 and 544, before it was overrun in 609. 
The stylistic changes characteristic of Late Antique art mark the end of classical Roman art and the beginnings of medieval art. As a complicated period bridging between Roman art and later medieval styles (such as that of the Byzantines), the Late Antique period saw a transition from the classical idealized realism tradition largely influenced by Ancient Greek art to the more iconic, stylized art of the Middle Ages.  Unlike classical art, Late Antique art does not emphasize the beauty and movement of the body, but rather, hints at the spiritual reality behind its subjects[ citation needed ]. Additionally, mirroring the rise of Christianity and the collapse of the western Roman Empire, painting and freestanding sculpture gradually fell from favor in the artistic community. Replacing them were greater interests in mosaics, architecture, and relief sculpture.
As the soldier emperors such as Maximinus Thrax (r. 235–238) emerged from the provinces in the 3rd century, they brought with them their own regional influences and artistic tastes. For example, artists jettisoned the classical portrayal of the human body for one that was more rigid and frontal. This is markedly evident in the combined porphyry Portrait of the Four Tetrarchs in Venice. With these stubby figures clutching each other and their swords, all individualism, naturalism, Roman verism, and Greek idealism diminish.   The Arch of Constantine in Rome, which re-used earlier classicising reliefs together with ones in the new style, shows the contrast especially clearly.  In nearly all artistic media, simpler shapes were adopted and once natural designs were abstracted. Additionally hierarchy of scale overtook the preeminence of perspective and other classical models for representing spatial organization.
From around 300 Early Christian art began to create new public forms, which now included sculpture, previously distrusted by Christians as it was so important in pagan worship. Sarcophagi carved in relief had already become highly elaborate, and Christian versions adopted new styles, showing a series of different tightly packed scenes rather than one overall image (usually derived from Greek history painting) as was the norm. Soon the scenes were split into two registers, as in the Dogmatic Sarcophagus or the Sarcophagus of Junius Bassus (the last of these exemplifying a partial revival of classicism). 
Nearly all of these more abstracted conventions could be observed in the glittering mosaics of the era, which during this period moved from being decoration derivative from painting used on floors (and walls likely to become wet) to a major vehicle of religious art in churches. The glazed surfaces of the tesserae sparkled in the light and illuminated the basilica churches. Unlike their fresco predecessors, much more emphasis was placed on demonstrating a symbolic fact rather than on rendering a realistic scene. As time progressed during the Late Antique period, art become more concerned with biblical themes and influenced by interactions of Christianity with the Roman state. Within this Christian subcategory of Roman art, dramatic changes were also taking place in the Depiction of Jesus. Jesus Christ had been more commonly depicted as an itinerant philosopher, teacher or as the "Good Shepherd", resembling the traditional iconography of Hermes. He was increasingly given Roman elite status, and shrouded in purple robes like the emperors with orb and scepter in hand — this new type of depiction is variously thought to be derived from either the iconography of Jupiter or of classical philosophers.
As for luxury arts, manuscript illumination on vellum and parchment emerged from the 5th century, with a few manuscripts of Roman literary classics like the Vergilius Vaticanus and the Vergilius Romanus, but increasingly Christian texts, of which Quedlinburg Itala fragment (420–430) is the oldest survivor. Carved ivory diptychs were used for secular subjects, as in the imperial and consular diptychs presented to friends, as well as religious ones, both Christian and pagan – they seem to have been especially a vehicle for the last group of powerful pagans to resist Christianity, as in the late 4th century Symmachi–Nicomachi diptych.  Extravagant hoards of silver plate are especially common from the 4th century, including the Mildenhall Treasure, Esquiline Treasure, Hoxne Hoard, and the imperial Missorium of Theodosius I. 
In the field of literature, Late Antiquity is known for the declining use of classical Greek and Latin, and the rise of literary cultures in Syriac, Armenian, Georgian, Ethiopic, Arabic, and Coptic. It also marks a shift in literary style, with a preference for encyclopedic works in a dense and allusive style, consisting of summaries of earlier works (anthologies, epitomes) often dressed up in elaborate allegorical garb (e.g., De nuptiis Mercurii et Philologiae [The Marriage of Mercury and Philology] of Martianus Capella and the De arithmetica, De musica, and De consolatione philosophiae of Boethius—both later key works in medieval education). The 4th and 5th centuries also saw an explosion of Christian literature, of which Greek writers such as Eusebius of Caesarea, Basil of Caesarea, Gregory of Nazianzus and John Chrysostom and Latin writers such as Ambrose of Milan, Jerome and Augustine of Hippo are only among the most renowned representatives. On the other hand, authors such as Ammianus Marcellinus (4th century) and Procopius of Caesarea (6th century) were able to keep the tradition of classical Hellenistic historiography alive in the Byzantine empire.
Greek poets of the Late Antique period included Antoninus Liberalis, Quintus Smyrnaeus, Nonnus, Romanus the Melodist and Paul the Silentiary.
Latin poets included Ausonius, Paulinus of Nola, Claudian, Rutilius Namatianus, Orientius, Sidonius Apollinaris, Corippus and Arator.
Jewish poets included Yannai, Eleazar ben Killir and Yose ben Yose.
Constantinople was the capital of the Roman Empire, and later, the Eastern Roman Empire, the Latin Empire (1204–1261), and the Ottoman Empire (1453–1922). Following the Turkish War of Independence, the Turkish capital then moved to Ankara. Officially renamed Istanbul in 1930, the city is today the largest city and financial centre of the Republic of Turkey (1923–present). It is also the largest city in Europe.
Justinian I, also known as Justinian the Great, was the Byzantine emperor from 527 to 565.
Classical antiquity is the period of cultural history between the 8th century BC and the 5th century AD centred on the Mediterranean Sea, comprising the interlocking civilizations of ancient Greece and ancient Rome known as the Greco-Roman world. It is the period in which both Greek and Roman societies flourished and wielded huge influence throughout much of Europe, North Africa, and Western Asia.
Edessa was an ancient city (polis) in Upper Mesopotamia, founded during the Hellenistic period by King Seleucus I Nicator, founder of the Seleucid Empire. It later became capital of the Kingdom of Osroene, and continued as capital of the Roman province of Osroene. In Late Antiquity, it became a prominent center of Christian learning and seat of the Catechetical School of Edessa. During the Crusades, it was the capital of the County of Edessa.
The Early Middle Ages, sometimes controversially referred to as the Dark Ages, is typically regarded by historians as lasting from the late 5th or early 6th century to the 10th century. They marked the start of the Middle Ages of European history, following the decline of the Western Roman Empire, and preceding the High Middle Ages. The alternative term late antiquity, for the early part of the period, emphasizes elements of continuity with the Roman Empire, while Early Middle Ages is used to emphasize developments characteristic of the earlier medieval period.
Byzantine Greece has a history that mainly coincides with that of the Byzantine Empire itself.
Byzantine art comprises the body of Christian Greek artistic products of the Eastern Roman Empire, as well as the nations and states that inherited culturally from the empire. Though the empire itself emerged from the decline of Rome and lasted until the Fall of Constantinople in 1453, the start date of the Byzantine period is rather clearer in art history than in political history, if still imprecise. Many Eastern Orthodox states in Eastern Europe, as well as to some degree the Islamic states of the eastern Mediterranean, preserved many aspects of the empire's culture and art for centuries afterward.
Greece in the Roman era describes the Roman conquest of Greece, as well as the period of Greek history when Greece was dominated first by the Roman Republic and then by the Roman Empire.
The Byzantine Iconoclasm were two periods in the history of the Byzantine Empire when the use of religious images or icons was opposed by religious and imperial authorities within the Orthodox Church and the temporal imperial hierarchy. The First Iconoclasm, as it is sometimes called, occurred between about 726 and 787, while the Second Iconoclasm occurred between 814 and 842. According to the traditional view, Byzantine Iconoclasm was started by a ban on religious images promulgated by the Byzantine Emperor Leo III the Isaurian, and continued under his successors. It was accompanied by widespread destruction of religious images and persecution of supporters of the veneration of images. The Papacy remained firmly in support of the use of religious images throughout the period, and the whole episode widened the growing divergence between the Byzantine and Carolingian traditions in what was still a unified European Church, as well as facilitating the reduction or removal of Byzantine political control over parts of the Italian Peninsula.
The Later Roman Empire spans the period from 284 AD to 641 in the history of the Roman Empire.
The Portrait of the Four Tetrarchs is a porphyry sculpture group of four Roman emperors dating from around 300 AD. The sculptural group has been fixed to a corner of the façade of St Mark's Basilica in Venice, Italy since the Middle Ages. It probably formed part of the decorations of the Philadelphion in Constantinople, and was removed to Venice in 1204 or soon after.
The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in Europe. The terms "Byzantine Empire" and "Eastern Roman Empire" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire, and to themselves as Romans—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued and its traditions were maintained, modern historians prefer to differentiate the Byzantine Empire from Ancient Rome as it was centred on Constantinople, oriented towards Greek rather than Latin culture, and characterised by Eastern Orthodox Christianity.
This history of the Byzantine Empire covers the history of the Eastern Roman Empire from late antiquity until the Fall of Constantinople in 1453 AD. Several events from the 4th to 6th centuries mark the transitional period during which the Roman Empire's east and west divided. In 285, the emperor Diocletian partitioned the Roman Empire's administration into eastern and western halves. Between 324 and 330, Constantine I transferred the main capital from Rome to Byzantium, later known as Constantinople and Nova Roma. Under Theodosius I, Christianity became the Empire's official state religion and others such as Roman polytheism were proscribed. And finally, under the reign of Heraclius, the Empire's military and administration were restructured and adopted Greek for official use instead of Latin. Thus, although it continued the Roman state and maintained Roman state traditions, modern historians distinguish Byzantium from ancient Rome insofar as it was oriented towards Greek rather than Latin culture, and characterised by Orthodox Christianity rather than Roman polytheism.
Christianity in late antiquity traces Christianity during the Christian Roman Empire – the period from the rise of Christianity under Emperor Constantine, until the fall of the Western Roman Empire. The end-date of this period varies because the transition to the sub-Roman period occurred gradually and at different times in different areas. One may generally date late ancient Christianity as lasting to the late 6th century and the re-conquests under Justinian of the Byzantine Empire, though a more traditional end-date is 476, the year in which Odoacer deposed Romulus Augustus, traditionally considered the last western emperor.
Christianity became the official religion of the Roman Empire when Emperor Theodosius I issued the Edict of Thessalonica in 380, which recognized the catholic orthodoxy of Nicene Christians in the Great Church as the Roman Empire's state religion. Most historians refer to the Nicene church associated with emperors in a variety of ways: as the catholic church, the orthodox church, the imperial church, the imperial Roman church, or the Byzantine church, although some of those terms are also used for wider communions extending outside the Roman Empire. The Eastern Orthodox Church, Oriental Orthodoxy, and the Catholic Church all claim to stand in continuity from the Nicene church to which Theodosius granted recognition.
Persecution of pagans in the late Roman Empire began during the reign of Constantine the Great in the military colony of Aelia Capitolina (Jerusalem), when he destroyed a pagan temple for the purpose of constructing a Christian church. Christian historians alleged that Hadrian had constructed a temple to Aphrodite on the site of the crucifixion of Jesus on Golgotha hill in order to suppress Jewish Christian veneration there. Constantine used that to justify the temple's destruction, saying he was simply reclaiming the property.
The Michaelion was one of the earliest and most famous sanctuaries dedicated to Saint Michael the Archangel in the Roman Empire. According to tradition, it was built in the 4th century by Emperor Constantine the Great over an ancient pagan temple, and was located just north of Constantinople, in the village of Sosthenion on the European shore of the Bosphorus strait.
A palladium or palladion is an image or other object of great antiquity on which the safety of a city or nation is said to depend. The word is a generalization from the name of the original Trojan Palladium, a wooden statue (xoanon) of Pallas Athena that Odysseus and Diomedes stole from the citadel of Troy. It was supposedly later taken to the future site of Rome by Aeneas, where it remained until perhaps transferred to Constantinople and was lost after the Empire converted to Christianity.
Byzantine mosaics are mosaics produced from the 4th to 15th centuries in and under the influence of the Byzantine Empire. Mosaics were some of the most popular and historically significant art forms produced in the empire, and they are still studied extensively by art historians. Although Byzantine mosaics evolved out of earlier Hellenistic and Roman practices and styles, craftspeople within the Byzantine Empire made important technical advances and developed mosaic art into a unique and powerful form of personal and religious expression that exerted significant influence on Islamic art produced in Umayyad and Abbasid Caliphates and the Ottoman Empire. In addition, Byzantine mosaics went on to influence artists in the Norman Kingdom of Sicily, in the Republic of Venice, and, carried by the spread of Orthodox Christianity, in Bulgaria, Serbia, Romania and Russia. In the modern era, artists across the world have drawn inspiration from their focus on simplicity and symbolism, as well as their beauty.
Hellenization in the Byzantine Empire describes the spread and intensification of ancient Greek culture, religion and language in the Byzantine Empire. The theory of Hellenization generally applies to the influence of foreign cultures subject to Greek influence or occupation, which includes the ethnic and cultural homogenisation which took place throughout the life of the Byzantine Empire (330-1453).
