Partitio terrarum imperii Romaniae

The (Latin for "partition of the lands of the empire of Romania [Byzantine Empire]) was a treaty signed amongst the crusaders after the sack of the Byzantine capital, Constantinople, by the Fourth Crusade in 1204. It established the Latin Empire and arranged the nominal partition of the Byzantine territory among the participants of the Crusade, with the Republic of Venice being the greatest titular beneficiary. However, because the crusaders did not in fact control most of the Empire, with local Byzantine Greek nobles establishing the Byzantine successor kingdoms (Empire of Nicaea, Empire of Trebizond, Despot of Epirus), most of the crusaders' declared division of the Empire amongst themselves could never be implemented.
