The Delian League

After the defeat of the second Persian invasion in 478 BCE, Greek city-states formed an alliance known as the Delian League, led by Athens and based on the island of Delos. Initially a cooperative pact to resist Persia, the League gradually became a tool for Athens to build its wealth and naval power. Cities that tried to leave were violently suppressed and their lands confiscated, transforming the alliance into what many consider an Athenian Empire. Melvyn Bragg and guests explore how this shift reshaped the geopolitics of the classical world.
