Eteocles and Polynices’ agreement to rule in turns

Eteocles and Polynices’ agreement to rule in turns was the succession arrangement at the center of the brothers’ conflict. Each was supposed to rule Thebes for a year; when Eteocles refused to give up the throne at the end of his first year, the arrangement collapsed into a fight that killed both brothers outside the city walls.

Terms and Breakdown

The agreement provided for the brothers to alternate as rulers, each holding the throne for one year. Its crucial condition was that Eteocles yield power when his first year ended. Instead, he refused, turning a planned transfer of rule into an unresolved struggle over the throne.

Consequences for Thebes

The brothers’ conflict ended in their mutual deaths outside Thebes. Seven foreign princes who had joined Polynices’ cause were defeated at the city’s seven gates; the city was saved, but the succession arrangement had left it without either of its rival claimants.

Political and Dramatic Significance

The agreement makes the conflict more than a contest between two brothers: it begins with a clear expectation of shared, alternating rule, then fails when that expectation is not honored. Its collapse sets the political circumstances in which Creon becomes king and distinguishes the brothers’ treatment after death: Creon orders a grand funeral for Eteocles while forbidding Polynices’ burial and declaring that anyone who performs the funeral rites will be put to death.
