Crusader state that replaced the Byzantine Empire from 1204–1261

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 CE until its disestablishment in 1261 CE. 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.

Latin Empire in Depth

History

Further duchies were projected in Asia Minor, at Nicaea (for Louis of Blois), Nicomedia (Thierry de Loos), Philadelphia (Stephen du Perche), and Neokastra. These duchies remained theoretical, due to the establishment of the Empire of Nicaea in the area. Nicaea itself was never occupied and Louis of Blois was killed in 1205. Thierry de Loos was captured by the Nicaeans in 1207 and, although released, left the Latin Empire two years later. After a brief Nicaean reconquest, Nicomedia returned to Latin control, but the ducatus Nichomedie remained part of the Imperial domain. Philadelphia never came under actual Latin control, although the Latin emperor Henry of Flanders laid claim to the region after defeating the local strongman, Theodore Mangaphas, in 1205.
