During the 2nd and 3rd centuries, Greece was divided into provinces including
Achaea,
Macedonia,
Epirus and
Thrace. During the reign of
Diocletian in the late 3rd century,
Moesia was organized as a
diocese, and was ruled by
Galerius. Under Constantine (who professed Christianity) Greece was part of the
prefectures of Macedonia and Thrace.
Theodosius divided the prefecture of Macedonia into the provinces of
Creta,
Achaea,
Thessalia,
Epirus Vetus,
Epirus Nova, and Macedonia. The
Aegean islands formed the province of
Insulae in the
Diocese of Asia. , ca. 1915. Greece faced invasions from the
Heruli,
Goths, and
Vandals during the reign of
Theodosius I.
Stilicho, who pretended he was a regent for
Arcadius, evacuated Thessaly when the
Visigoths invaded in the late 4th century. Arcadius' chief advisor
Eutropius allowed
Alaric to enter Greece, and he looted Athens, Corinth and the
Peloponnese. Stilicho eventually drove him out around 397 AD and Alaric was made
magister militum in
Illyricum. Eventually, Alaric and the Goths migrated to Italy, sacked Rome in 410, and built the
Visigothic Kingdom in
Iberia, which lasted until 711 with the
advent of the Arabs. Greece remained part of and became the center of the remaining relatively cohesive and robust eastern half of the Roman Empire, the Eastern Roman Empire (now historiographically referred to as the
Byzantine Empire), for nearly a thousand more years after the
Fall of Rome, the city which once conquered it. Contrary to outdated visions of
late antiquity, the Greek peninsula was most likely one of the most prosperous regions of the Roman Empire. Older scenarios of poverty, depopulation, barbarian destruction, and civil decay have been revised in light of recent archaeological discoveries. In fact, the
polis, as an institution, appears to have remained prosperous until at least the 6th century, despite the so-called 'decline and fall' in the west. Contemporary texts such as Hierocles'
Syndekmos affirm that late antique Greece was highly urbanised and contained approximately eighty cities. This view of broad prosperity is widely accepted today, and it is assumed between the 4th and 7th centuries AD, Greece continued as one of the most economically active regions in the eastern
Mediterranean. The Roman emperor
Heraclius in the early 7th century changed the empire’s official language from Latin to Greek. As the eastern half of the Mediterranean had always been predominantly Greek, the eastern (and thus the continuing) part of the Roman Empire gradually became Hellenized following the
fall of the Latin western empire. Over the course of the following centuries, mainland Greece was mainly contested between the Roman and Bulgarian Empires, and suffered from invasions by Slavic tribes and Normans. Crete and Cyprus were contested between the Romans and Arabs and were later taken by the Crusaders who, following the
Sack of Constantinople in 1204, established the
Latin Empire in Greece. The Romans retook Constantinople and re-established control in most of the Greek peninsula, although Epirus would remain an independent splinter state until the early 14th century when Roman control was re-established. As civil strife continued to beset the late-Byzantine empire, the Serbian Empire took the opportunity to conquer most of mainland Greece, while a resurgent Bulgarian Empire invaded from the north. In the century that followed, the
Ottoman Empire would establish its dominance in the region, annexing all three empires and finishing its conquest of Greece with the fall of the Morea in 1460. ==References==
