Kingdom of Thessalonica
In 1205 Ravano was among those who led forces in the capture of the island of Euboea from the Byzantine Empire as part of the Fourth Crusade. The island was made subject to the Kingdom of Thessalonica and in August King Boniface divided the island into thirds, granting probably the central third to Ravano. The rulers of Euboea (Negroponte to the Italians) were called "terzieri" or triarchs: rulers of thirds.
