The Cretan League or Koinon of the Cretans (Greek, Ancient (to 1453);: τὸ κοινὸν τῶν Κρητῶν|to koinon ton Kreton, originally Greek, Ancient (to 1453);: τὸ κοινὸν τῶν Κρηταιέων) was a federal league of ancient Greek city-states on the island of Crete. It was established in the 3rd century BC to preserve its members' independence against the hegemonic aspirations of Macedonia, and did not originally include all cities on the island, whence a distinction was made between the (the members of the League) and the more generic (Cretans); the League did not acquire its final name until the entire island found itself under the rule of the Roman Empire in the late 1st century BC. In its original form, the League lacked common institutions apart from a federal council and a federal court, and leadership was disputed between the cities of Gortyn and Knossos. After the Roman conquest in 67 BC, the island became part of the province of Crete and Cyrenaica, and the League was re-established as a common union of all cities on the island. A League president and later a chief priest of the Roman Imperial cult were created. Delegated to celebrating festivals and representing local grievances to the Roman imperial authorities, the League survived until the late 4th century AD.
