Sophocles was an ancient Greek tragedian, known as one of three from whom at least one play has survived in full. His first plays were written later than, or contemporary with, those of Aeschylus; and earlier than, or contemporary with, those of Euripides. Sophocles wrote over 120 plays, but only seven have survived in a complete form: Ajax, Antigone, Women of Trachis, Oedipus Rex, Electra, Philoctetes, and Oedipus at Colonus. For almost fifty years, Sophocles was the most celebrated playwright in the dramatic competitions of the city-state of Athens which took place during the religious festivals of the Lenaea and the Dionysia. He competed in thirty competitions, won twenty-four, and was never judged lower than second place. Aeschylus won thirteen competitions, and was sometimes defeated by Sophocles; Euripides won four.

The city of Athens during the classical period of ancient Greece was the major urban centre of the notable polis (city-state) of the same name, located in Attica, Greece, leading the Delian League in the Peloponnesian War against Sparta and the Peloponnesian League. Athenian democracy was established in 508 BC under Cleisthenes following the tyranny of Isagoras. This system remained remarkably stable, and with a few brief interruptions remained in place for 180 years, until 322 BC. The peak of Athenian hegemony was achieved in the 440s to 430s BC, known as the Age of Pericles.
