BIOGRAPHICAL DOSSIER
Life and historical role
Life and political setting
Baldwin was a younger son of the comital house of Boulogne and was initially prepared for an ecclesiastical career. During the First Crusade he separated from the main army and moved through Cilicia toward Edessa. After the death of the Armenian ruler Thoros in 1098, Baldwin established the first Latin principality of the expedition at Edessa.
Role in the Crusades
Following Godfrey's death, Baldwin went to Jerusalem and was crowned king in 1100. The capture of coastal centres including Arsuf, Caesarea, Acre, Beirut and Sidon widened the kingdom's access to maritime supply and Italian naval assistance. Victories and reverses against Fatimid armies around Ramla marked the early defence of the new monarchy.
