The Delian League

Misha Glenny and guests discuss the origins and evolution of an alliance which transformed the geopolitics of the classical world: the Delian League. Since the start of the 5th Century BCE, city states across Greece had been fighting a series of armed conflicts in the Greco-Persian Wars. After the defeat of a second Persian invasion in 478 BCE, a league of cities across Greece came together and formed a new alliance led by Athens. That alliance is now known as the Delian League, after the island of Delos where it was established. In the following decades, Athens used the Delian League to grow its own wealth and formidable naval power. Cities which tried to leave the alliance found themselves violently put down and their lands confiscated by the Athenians. What had begun as a cooperative alliance sworn to resist the Persian Empire gradually started to seem like it may have created another imperial power: the Athenian Empire.
