The Kingdom of Thessalonica (Greek: Βασίλειον τῆς Θεσσαλονίκης, romanized: Vasílion tis Thessaloníkis) was a short-lived Crusader State established as a vassal of the Latin Empire following the Fourth Crusade. It was formed from the partition of Byzantine lands in today's territory of Northern Greece with Thessaloniki as its capital. The kingdom faced continual pressure from neighboring powers and it collapsed after being conquered by the Despotate of Epirus in 1224.
