The Epizephyrian League was an ancient Greek confederation formed by several cities in the region of southern Italy, particularly around the area of Tarentum. This league was established in the 4th century BCE and primarily included cities like Locri, Croton, and Syracuse. Its main purpose was to promote mutual defense and cooperation among its member states. The league played a significant role in the political landscape of the time, especially in countering the influence of other powers, such as the Lucanians and Bruttians. The Epizephyrian League also facilitated trade and cultural exchange among its members, contributing to the development of the region.
