Athens leads a new alliance, the Delian League
The Greek allies make Athens their leader against Persia. Each city owes ships or money, and the common treasury is kept on the island of Delos.
The tribute was first fixed at four hundred and sixty talents. The common treasury was at Delos, and the congresses were held in the temple.
