The army of Godfrey of Bouillon, the duke of Lower Lorraine, in response to the call by Pope Urban II to both liberate Jerusalem from Muslim forces and protect the Byzantine Empire from similar attacks. Godfrey and his army, one of several Frankish forces deployed during the First Crusade, was among the first to arrive in Constantinople. The army was unique in that it included among its warriors the first three kings of Jerusalem, although Godfrey preferred the title Defender of the Holy Sepulchre, Advocatus Sancti Sepulchri, as he believed that the true King of Jerusalem was Christ. This article focuses on the members of the army rather that its exploits which are described in detail in Godfrey’s biography as well as numerous sources listed below.
