Classical antiquity in the Mediterranean region is commonly considered to have begun in the 8th century BC (around the time of the earliest recorded poetry of Homer) and ended in the 6th century AD. Classical antiquity in Greece was preceded by the Greek Dark Ages (c. 1200 – c. 800 BC), archaeologically characterised by the protogeometric and geometric styles of designs on pottery. Following the Dark Ages was the Archaic Period, beginning around the 8th century BC, which saw early developments in Greek culture and society leading to the Classical Period[6] from the Persian invasion of Greece in 480 until the death of Alexander the Great in 323. The Classical Period is characterized by a "classical" style, i.e. one which was considered exemplary by later observers, most famously in the Parthenon of Athens. Politically, the Classical Period was dominated by Athens and the Delian League during the 5th century, but displaced by Spartan hegemony during the early 4th century BC, before power shifted to Thebes and the Boeotian League and finally to the League of Corinth led by Macedon. This period was shaped by the Greco-Persian Wars, the Peloponnesian War, and the Rise of Macedon. Following the Classical period was the Hellenistic period (323–146 BC), during which Greek culture and power expanded into the Near and Middle East from the death of Alexander until the Roman conquest. Roman Greece is usually counted from the Roman victory over the Corinthians at the Battle of Corinth in 146 BC to the establishment of Byzantium by Constantine as the capital of the Roman Empire in AD 330. Finally, Late Antiquity refers to the period of Christianization during the later 4th to early 6th centuries AD, consummated by the closure of the Academy of Athens by Justinian I in 529.
