The Ancient Greeks lived in Greece and surrounding areas from around 3500 BC to 146 BC. They created the first Olympic games in 776 BC and produced famous epics and plays in the 5th century BC. Key city-states like Athens and Sparta grew powerful but often argued, and Greece was eventually conquered by the Roman Empire in 146 BC. The Greeks were talented thinkers, artists, and athletes who built temples and theaters and laid the foundations of Western civilization.
