Mycenaean Greece was the last phase of the Bronze Age in ancient Greece, spanning the period from approximately 1750 to 1050 BC. It represents the first advanced and distinctively Greek civilization in mainland Greece with its palatial states, urban organization, works of art, and writing system. The Mycenaeans were mainland Greek peoples who were likely stimulated by their contact with insular Minoan Crete and other Mediterranean cultures to develop a more sophisticated sociopolitical culture of their own. The most prominent site was Mycenae, after which the culture of this era is named. Other centers of power that emerged included Pylos, Tiryns, and Midea in the Peloponnese, Orchomenos, Thebes, and Athens in Central Greece, and Iolcos in Thessaly. Mycenaean settlements also appeared in Epirus, Macedonia, on islands in the Aegean Sea, on the south-west coast of Asia Minor, and on Cyprus, while Mycenaean-influenced settlements appeared in the Levant and Italy.

Ancient Greece was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity, that comprised a loose collection of culturally and linguistically related city-states and other territories. Most of these regions were officially unified only once, for 13 years, under Alexander the Great's empire from 336 to 323 BC. In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period.
