The Latin Empire, also referred to as the Latin Empire of Constantinople or the Constantinopolitan Empire, was a feudal Crusader state founded by the leaders of the Fourth Crusade on lands captured from the Byzantine Empire. It existed from 1204 C.E until its disestablishment in 1261 C.E. The Latin Empire was intended to replace the Byzantine Empire as the Western-recognized Roman Empire in the east, with a Catholic emperor enthroned in place of the Eastern Orthodox Roman emperors. The main objective to form a Latin Empire was planned over the course of the Fourth Crusade, promoted by crusade leaders such as Boniface I of Montferrat, as well as the Republic of Venice.
