The end of the Dark Ages is traditionally dated to 776 BC, the year of the first Olympic Games. The Iliad and the Odyssey, the foundational texts of Western literature, are believed to have been composed by Homer in the 8th or 7th centuries BC With the end of the Dark Ages, there emerged various kingdoms and city-states across the Greek peninsula, which spread to the shores of the Black Sea, Southern Italy (Latin: Magna Graecia, or Greater Greece) and Asia Minor. These states and their colonies reached great levels of prosperity that resulted in an unprecedented cultural boom, that of classical Greece, expressed in architecture, drama, science, mathematics and philosophy. In 508 BC, Cleisthenes instituted the world's first democratic system of government in Athens.
