Byzantine Dark Ages is a historiographical term for the period in the history of the Eastern Roman (Byzantine) Empire, during the 7th and 8th centuries, which marks the transition between the late antique early Byzantine period and the "medieval" middle Byzantine era. The "Dark Ages" are characterized by widespread upheavals and transformation of the Byzantine state and society, resulting in a paucity of historical sources.
The 7th century was a watershed in the history of the Byzantine Empire. At its beginning, the Eastern Roman Empire still controlled most of the Mediterranean Basin's shores and faced the Sassanian Empire as its main eastern rival. The Fall of the Western Roman Empire had eroded this traditional order, and despite Emperor Justinian I's wars of reconquest in the 6th century, many of his gains in Italy and Spain were quickly undone. But it was still recognizably the late antique world dominated by the Roman Empire, with the Mediterranean mare nostrum as its center of gravity and cities as the main social and economic unit. [1]
The final Byzantine-Sassanid War weakened this world, but the Muslim conquests of the 7th century shattered it for good. The emergent caliphate was not only far more powerful and threatening than Persia had ever been, but it also shattered the political unity of the Mediterranean world and moved the center of power east, first to Damascus and then to Baghdad. Byzantium was left territorially crippled, reduced to the status of a peripheral power, and on a permanent defensive against invaders from all sides. [1]
This crisis led to a profound transformation in the nature and culture of the Byzantine state, that was not completed until the 9th century, when the Muslim pressure on the Empire slackened. [2] The Byzantine state that emerged "was an empire and culture focused on emperor and capital." [3] It was also much more militarized: The civilian late-antiquity administrative structure, put in place by Diocletian and his successors, was replaced by the themes, each governed by a military commander ( strategos , "general"). The rigid distinction between civilian and military hierarchies, which was a hallmark of the late antique system, was thus abolished. [4] With the territorial losses reducing the Empire to its core territories in Anatolia and parts of the Balkans, the administration was streamlined, with the central government essentially absorbing the old provincial administration of the praetorian prefectures into a centralized, court-centered hierarchy. In the process, the handful of great departments of late antiquity were replaced by a series of smaller, more narrowly focused fiscal bureaus, all of roughly equal status. [5] Another change was that Greek also finally replaced Latin as the language of administration during this period. [6]
The Muslim conquests, coupled with the Slavic migrations to Southeastern Europe around the same time, resulted in the breakdown of the late-antiquity social order. In some instances, cities were reduced to small fortified settlements, notable mainly as defensive bastions and market centers; the Byzantine capital, Constantinople, remained highly populated. [7] The provincial aristocracy declined; offices such as the decurions of the cities disappeared and with them the political functions of the landed aristocracy. The great landholders of late antiquity were ruined by the constant invasions, and those who survived appear to have left the cities to fortified country estates. [8] Many of the provincial aristocracy during this period managed to retain — or gain — their positions through holding offices in the themes, and gradually, they too became militarized. [8]
Education suffered a severe blow during this period. Some form of higher education was still available in the capital; albeit, there too few figures of prominence are known, and private education was still available for the wealthy, but acquiring it was much more difficult. In particular, education in Roman law, which had been the basis for a public career, suffered an abrupt decline, aided by the fact that legal teaching had traditionally been in the hands of a small group of mostly pagan professors. [9] The numerical and qualitative decline of the educated classes had, as a result, the decline in the number of philological works produced, as the remaining audience for such works was small and diminishing with every passing year. [10] Art and architecture followed suit, with many quarries being abandoned. Apart from fortifications —often quite hastily executed — almost all building activity ceased during this period. [11]
Examining this crucial period in Byzantine history has posed many difficulties to modern scholars, as the Byzantine historical sources about it are few and mostly originated later than the period itself. [3] No Byzantine historical source is known from the end of the last great Byzantine–Sassanid war around 630 until the late 8th century, when Patriarch Nikephoros I of Constantinople wrote his Brief History, followed a few decades later by the Chronicle of Theophanes the Confessor. [12] Administrative and legal sources are also scarce, with the "Farmer's Law" and the "Rhodian Sea Law" the only exceptions. [13] Much of the information for this period is thus derived from non-Byzantine sources, such as the Arab historians, as well as Armenian and Syriac sources from the Empire's periphery, although many of them are of a later date as well. [13]
Theological works are an exception to this scarcity of sources, but again, due to the decline of the educated classes in Byzantium itself, most of these were written in the Empire's periphery or indeed in lands controlled by the caliphate, while works from Constantinople are almost entirely absent. [14] [15] Active theologians include Maximus the Confessor and Germanus I of Constantinople, while scholars such as John of Damascus were active in Syria after the early Muslim conquests. [16]
Theodosius III was Byzantine emperor from c. May 715 to 25 March 717. Before rising to power and seizing the throne of the Byzantine Empire, he was a tax collector in Adramyttium. In 715, the Byzantine navy and the troops of the Opsician Theme, one of the Byzantine provinces, revolted against Emperor Anastasius II, acclaiming the reluctant Theodosius as emperor. Theodosius led his troops to Chrysopolis and then Constantinople, the capital, seizing the city in November 715. Anastasius did not surrender until several months later, accepting exile in a monastery in return for safety. Many themes viewed Theodosius to be a puppet of the troops of the Opsician Theme, and his legitimacy was denied by the Anatolics and the Armeniacs under their respective strategoi (generals) Leo the Isaurian and Artabasdos.
The themes or thémata were the main military and administrative divisions of the middle Byzantine Empire. They were established in the mid-7th century in the aftermath of the Slavic migrations to Southeastern Europe and Muslim conquests of parts of Byzantine territory, and replaced the earlier provincial system established by Diocletian and Constantine the Great. In their origin, the first themes were created from the areas of encampment of the field armies of the East Roman army, and their names corresponded to the military units that had existed in those areas. The theme system reached its apogee in the 9th and 10th centuries, as older themes were split up and the conquest of territory resulted in the creation of new ones. The original theme system underwent significant changes in the 11th and 12th centuries, but the term remained in use as a provincial and financial circumscription until the very end of the Empire.
Tiberius III, born Apsimar, was Byzantine emperor from 698 to 705. Little is known about his early life, other than that he was a droungarios, a mid-level commander, who served in the Cibyrrhaeot Theme. In 696, Tiberius was part of an army sent by Byzantine Emperor Leontius to retake the North African city of Carthage, which had been captured by the Arab Umayyads. After seizing the city, this army was pushed back by Umayyad reinforcements and retreated to the island of Crete. As they feared the wrath of Leontius, some officers killed their commander, John the Patrician, and declared Tiberius the emperor. Tiberius swiftly gathered a fleet and sailed for Constantinople, where he then deposed Leontius. Tiberius did not attempt to retake Byzantine Africa from the Umayyads, but campaigned against them along the eastern border with some success. In 705, former emperor Justinian II, who had been deposed by Leontius, led an army of Slavs and Bulgars from the First Bulgarian Empire to Constantinople, and after entering the city secretly, deposed Tiberius. Tiberius fled to Bithynia, but was captured a few months later and beheaded by Justinian between August 705 and February 706. His body was initially thrown into the sea, but was later recovered and buried in a church on the island of Prote.
Constantine V was Byzantine emperor from 741 to 775. His reign saw a consolidation of Byzantine security from external threats. As an able military leader, Constantine took advantage of civil war in the Muslim world to make limited offensives on the Arab frontier. With this eastern frontier secure, he undertook repeated campaigns against the Bulgars in the Balkans. His military activity, and policy of settling Christian populations from the Arab frontier in Thrace, made Byzantium's hold on its Balkan territories more secure. He was also responsible for important military and administrative innovations and reforms.
The tagma is a military unit of battalion or regiment size, especially the elite regiments formed by Byzantine emperor Constantine V and comprising the central army of the Byzantine Empire in the 8th–11th centuries.
The Byzantine army was the primary military body of the Byzantine armed forces, serving alongside the Byzantine navy. A direct continuation of the Eastern Roman army, shaping and developing itself on the legacy of the late Hellenistic armies, it maintained a similar level of discipline, strategic prowess and organization. It was among the most effective armies of western Eurasia for much of the Middle Ages. Over time the cavalry arm became more prominent in the Byzantine army as the legion system disappeared in the early 7th century. Later reforms reflected some Germanic and Asian influences—rival forces frequently became sources of mercenary units, such as the Huns, Cumans, Alans and Turks, meeting the Empire's demand for light cavalry mercenaries. Since much of the Byzantine military focused on the strategy and skill of generals utilizing militia troops, heavy infantry were recruited from Frankish and later Varangian mercenaries.
A droungarios, also spelled drungarios and sometimes anglicized as Drungary, was a military rank of the late Roman and Byzantine empires, signifying the commander of a formation known as droungos.
Logothete was an administrative title originating in the eastern Roman Empire. In the middle and late Byzantine Empire, it rose to become a senior administrative title, equivalent to a minister or secretary of state. The title spread to other states influenced by Byzantine culture, such as Bulgaria, Sicily, Serbia, and the Danubian Principalities.
The Byzantine Greeks were the Greek-speaking Eastern Romans throughout Late Antiquity and the Middle Ages. They were the main inhabitants of the lands of the Byzantine Empire, of Constantinople and Asia Minor, the Greek islands, Cyprus, and portions of the southern Balkans, and formed large minorities, or pluralities, in the coastal urban centres of the Levant and northern Egypt. Throughout their history, the Byzantine Greeks self-identified as Romans, but are referred to as "Byzantine Greeks" in modern historiography. Latin speakers identified them simply as Greeks or with the term Romaei.
Macedonian Renaissance is a historiographical term used for the blossoming of Byzantine culture in the 9th–11th centuries, under the eponymous Macedonian dynasty (867–1056), following the upheavals and transformations of the 7th–8th centuries, also known as the "Byzantine Dark Ages". The period is also known as the era of Byzantine encyclopedism, because of the attempts to systematically organize and codify knowledge, exemplified by the works of the scholar-emperor Constantine VII Porphyrogennetos.
The Excubitors were founded in c. 460 as an imperial guard-unit by the Byzantine emperor Leo I the Thracian. The 300-strong force, originally recruited from among the warlike mountain tribe of the Isaurians, replaced the older Scholae Palatinae as the main imperial bodyguards. The Excubitors remained an active military unit for the next two centuries, although, as imperial bodyguards, they did not often go on campaign. Their commander, the Count of the Excubitors, soon acquired great influence. Justin I was able to use this position to rise to the throne in 518, and thereafter the Counts of the Excubitors were among the main political power-holders of their day; two more, Tiberius II Constantine and Maurice, rose to become emperors in the late 6th century.
The Byzantine Empire was ruled by the Isaurian dynasty from 717 to 802. The Isaurian emperors were successful in defending and consolidating the empire against the caliphates after the onslaught of the early Muslim conquests, but were less successful in Europe, where they suffered setbacks against the Bulgars, had to give up the Exarchate of Ravenna, and lost influence over Italy and the papacy to the growing power of the Franks.
The Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire centred in Constantinople during late antiquity and the Middle Ages. The eastern half of the Empire survived the conditions that caused the fall of the West in the 5th century AD, and continued to exist 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 the Mediterranean world. The term "Byzantine Empire" was only coined following the empire's demise; its citizens referred to the polity as the "Roman Empire" and to themselves as "Romans". Due to the imperial seat's move from Rome to Byzantium, the adoption of state Christianity, and the predominance of Greek instead of Latin, modern historians continue to make a distinction between the earlier Roman Empire and the later Byzantine Empire.
The Byzantine Empire's history is generally periodised from late antiquity until the Fall of Constantinople in 1453 AD. From the 3rd to 6th centuries, the Greek East and Latin West of the Roman Empire gradually diverged, marked by Diocletian's formal partition of its administration in 285, the establishment of an eastern capital in Constantinople by Constantine I in 330, and the adoption of Christianity as the state religion under Theodosius I, with others such as Roman polytheism being proscribed. Under the reign of Heraclius, the Empire's military and administration were restructured and adopted Greek for official use instead of Latin. While there was an unbroken continuity in administration and other features of Roman society, historians have often distinguished the Byzantine epoch from earlier eras in Roman history for reasons including the imperial seat moving from Rome to Constantinople and the predominance of Greek instead of Latin.
Domestikos, in English sometimes [the] Domestic, was a civil, ecclesiastic and military office in the Late Roman Empire and the Byzantine Empire.
The Vigla, also known as the Arithmos and in English as the Watch, was one of the elite tagmata of the Byzantine army. It was established in the latter half of the 8th century, and survived until the late 11th century. Along with the Noumeroi regiment, the Vigla formed the guard of the imperial palace in Constantinople, and was responsible for the Byzantine emperor's safety on expeditions.
The Karabisianoi, sometimes anglicized as the Carabisians, were the main forces of the Byzantine navy from the mid-seventh until the early eighth centuries. The name derives from a term for ships, and means "people of the ships". The Karabisianoi were the first new and permanent naval establishment of the Byzantine Empire, formed to confront the early Muslim conquests at sea. They were disbanded and replaced with a series of maritime themes sometime in 718–730.
The Opsician Theme or simply Opsikion was a Byzantine theme located in northwestern Asia Minor. Created from the imperial retinue army, the Opsikion was the largest and most prestigious of the early themes, being located closest to Constantinople. Involved in several revolts in the 8th century, it was split in three after ca. 750, and lost its former pre-eminence. It survived as a middle-tier theme until after the Fourth Crusade.
Markeli was a medieval Byzantine and Bulgarian frontier stronghold, the ruins of which are located in Karnobat Municipality, Burgas Province, southeastern Bulgaria. Dating to Late Antiquity, the castle lay some 7.5 kilometres from the modern town of Karnobat. It was the site of two notable medieval battles between Byzantines and Bulgarians, the Battle of Marcellae of 756 and the Battle of Marcellae of 792.
In the Byzantine Empire, cities were centers of economic and cultural life. A significant part of the cities were founded during the period of Greek and Roman antiquity. The largest of them were Constantinople, Alexandria, Thessaloniki and Antioch, with a population of several hundred thousand people. Large provincial centers had a population of up to 50,000. Although the spread of Christianity negatively affected urban institutions, in general, late antique cities continued to develop continuously. Byzantium remained an empire of cities, although the urban space had changed a lot. If the Greco-Roman city was a place of pagan worship and sports events, theatrical performances and chariot races, the residence of officials and judges, then the Byzantine city was primarily a religious center where the bishop's residence was located.
