Sparta, one of the most powerful city-states in ancient Greece, had several allies throughout its history. One of the most notable culture regions that allied with Sparta was the Peloponnesian League. This alliance was formed in the 6th century BCE and included various city-states and regions in the Peloponnese, such as Corinth, Elis, and Tegea.
The Peloponnesian League was primarily a military alliance, and its members were obligated to support Sparta in times of war. This alliance played a crucial role in the Peloponnesian War (431-404 BCE), where Sparta and its allies fought against Athens and the Delian League. The Peloponnesian League’s support was instrumental in Sparta’s eventual victory over Athens.
In addition to the Peloponnesian League, Sparta also had alliances with other regions and city-states outside the Peloponnese, such as Thebes and Syracuse, at different times. These alliances were often based on mutual interests and the need for military support against common enemies.
