BIOGRAPHICAL DOSSIER
Life and historical role
Life and political setting
Thoros was an Armenian governor holding the Byzantine title of kouropalates who ruled Edessa semi-independently under Seljuk pressure. He tried to keep a difficult balance between the city's Armenian population and the surrounding Turkish emirs.
Role in the Crusades
In early 1098 he called on Baldwin of Boulogne, who had left the main crusader army, for help. Thoros adopted Baldwin in a formal ceremony, making him his heir and co-ruler. In March 1098 Thoros was killed in an uprising in the city, and Baldwin became sole ruler of Edessa, founding the first crusader state.
Historical significance and source problems
Baldwin's role in the uprising is disputed: Matthew of Edessa implies that Baldwin was in contact with the rebels; Fulcher of Chartres does not blame him. Thoros's story shows the fragility of the crusaders' relations with local Christian rulers.
