Latin Empire
feudal Crusader state founded by the leaders of the Fourth Crusade on lands captured from the Byzantine Empire
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.
The Fourth Crusade had originally been called to retake the Muslim-controlled city of Jerusalem, but a sequence of economic and political events culminated in the Crusader army sacking the city of Constantinople, the capital of the Byzantine Empire. Originally, the plan had been to restore the deposed Byzantine Emperor Isaac II Angelos to the throne, which had been usurped by Alexios III Angelos. The crusaders had been promised financial and military aid by Isaac's son Alexios IV, with which they had planned to continue to Jerusalem. When the crusaders reached Constantinople, the situation quickly turned volatile, and while Isaac and Alexios briefly ruled, the crusaders did not receive the payment they had hoped for. In April 1204, they captured and plundered the city's enormous wealth.
The crusaders selected their own emperor from among their own ranks, Baldwin IX of Flanders, and divided the territory of the Byzantine Empire into various new vassal crusader states. The Latin Empire's authority was immediately challenged by Byzantine rump states led by the Laskaris family (connected to the Angelos dynasty of 1185–1204) in Nicaea, by the Komnenos family (which had ruled as Byzantine Emperors 1081–1185) in Trebizond, and by the Komnenos Doukas family in Epirus and Thessalonica (especially from 1224 to 1242).

Why this record matters
“Latin Empire” is worth following because a concise public description often conceals a longer documentary argument. Here, Latin, Empire and feudal provides the most credible route into that argument.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q178897. VIAF identifies the subject as 6565148574362524430002. The Library of Congress control number is sh85074940. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1204, 1261, 1185 and 1081.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
