Greek theatre began in 534 BC in Athens, where the first theatre was created to host plays about the gods in honor of Dionysus. Plays were attended by up to 15,000 people and were an important social event, even allowing prisoners to attend. Only men could perform in plays initially, with women's roles played by men in drag. Plays told stories through song instead of lines, with actors using gestures and masks to convey meaning. Tragedies, comedies, and satyr plays were the main genres, with tragedy and comedy seen as separate. Athens spread these theatre traditions to its allies to promote a shared culture.
