Context Sack of Constantinople during the Fourth Crusade
Signed 1204 (1204)
Location Constantinople, Latin Empire
(now Istanbul, Turkey)

The Partitio terrarum imperii Romaniae (Latin for "partition of the lands of the empire of Romania[1] [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.

The treaty, which was promulgated either in late September / early October 1204 or (according to Nikolaos Oikonomides) immediately after the sack in April–May 1204, was drafted by a 24-man committee consisting of 12 Venetians and 12 representatives of the other Crusader leaders. It gave the Latin Emperor direct control of one fourth of the Byzantine territory, to Venice three eighths – including three eighths of the city of Constantinople, with Hagia Sophia – and the remaining three eighths were apportioned among the other Crusader chiefs. Through this division, Venice became the chief power in Latin Romania, and the effective power behind the Latin Empire, a fact clearly illustrated by the lofty title its Doge acquired: Dominator quartae et dimidiae partis totius Romaniae ("Lord of a quarter and a half quarter of all of Romania").


The Partitio Romaniae initiated the period of the history of Greece known as Frankokratia or Latinokratia ("Frankish/Latin rule"), where Catholic West European nobles, mostly from France and Italy, established states on former Byzantine territory and ruled over the mostly Orthodox native Byzantine Greeks. The provisions of the Partitio Romaniae were not fully carried out; much of the Byzantine realm fell into the hands not of the crusaders who had sacked the capital but of the local Byzantine Greek nobles, who established the Byzantine successor states of the Despotate of Epirus, the Empire of Nicaea and the Empire of Trebizond, while the Crusaders also squabbled among themselves. The Latin Empire itself, consisting of the area surrounding Constantinople, Thrace, and the Sea of Marmara was also drawn into a disastrous conflict with the powerful Second Bulgarian Empire. Latin rule became most firmly established and lasted longest in southern Greece (the Principality of Achaea and the Duchy of Athens), as well as the Aegean islands, which came largely under the control of Venice.

Importance as a historical source

As the division was based on now lost documents and tax registers from the Byzantine imperial chancery, the Partitio Romaniae is a valuable document for the administrative divisions (episkepseis) and estates of the various Byzantine magnate families ca. 1203, as well as the areas still controlled by the Byzantine central government at the time.
