Overview
The Peloponnesian League () was an alliance of ancient Greek city-states, dominated by Sparta and centred on the Peloponnese, which lasted from c. 550 to 366 BC. It is known mainly for being one of the two rivals in the Peloponnesian War (431–404 BC), against the Delian League, which was dominated by Athens.
