The theatre of Ancient Greece, or ancient Greek drama, is a theatrical culture that flourished in ancient Greece between 550 BC and 220 BC. The city-state of Athens, which became a significant cultural, political, and military power during this period, was its centre, where it was institutionalised as part of a festival called the Dionysia, which honoured the god Dionysus. Tragedy (late 6th century BC), comedy (486 BC), and the satyr play were the three dramatic genres to emerge there. Athens exported the festival to its numerous colonies and allies in order to promote a common cultural identity.
