The prehistory of Southeastern Europe, defined roughly as the territory of the wider Balkan peninsula (including the territories of the modern countries of Albania, Kosovo, Croatia, Serbia, Macedonia, Greece, Bosnia, Romania, Bulgaria, Moldova and Turkey) covers the period from the Upper Paleolithic, beginning with the presence of Homo sapiens in the area some 44,000 years ago, until the appearance of the first written records in Classical Antiquity, in Greece as early as the 8th century BC.
Human prehistory in Southeastern Europe is conventionally divided into smaller periods, such as Upper Paleolithic, Holocene Mesolithic/Epipaleolithic, Neolithic Revolution, expansion of Proto-Indo-Europeans, and Protohistory. The changes between these are gradual. For example, depending on interpretation, protohistory might or might not include Bronze Age Greece (2800–1200 BC),Minoan, Mycenaean, Thracian and Venetic cultures. By one interpretation of the historiography criterion, Southeastern Europe enters protohistory only with Homer (See also Historicity of the Iliad, and Geography of the Odyssey). At any rate, the period ends before Herodotus in the 5th century BC.
