The city-state of Athens was a great cultural, political and military power during this period. Drama was at its centre. Theatre was part of a festival called the Dionysia, which honoured the god Dionysus. In the Dionysia, the playwrights presented their work to an audience. It was a competition, with a winner and prizes. These two main genres were never mixed: they each had their own typical structure. Athens exported the festival to its numerous colonies and allies in order to promote their way of life.
