Baldwin I of Jerusalem fought for their brother, Godfrey of Bouillon, against Albert III, Count of Namur and Theoderic, Bishop of Verdun at Stenay in 1086. The childless Godfrey, who became duke of Lower Lotharingia in 1087, mentioned Baldwin in most of his charters of grant, indicating that Baldwin was regarded as his heir. Baldwin regularly visited the fortress of his wife's family at Conches-en-Ouche. Pope Urban II proclaimed the First Crusade at the Council of Clermont on 27November 1095. Godfrey of Bouillon decided to join the military campaign and sold or mortgaged his inherited domains to raise funds. One of his domains, the
Adhemar of Le Puy Crusade. Adhemar most likely met Pope Urban II, when in August 1095 Pope Urban the Second visited Puy. At the Council of Clermont in 1095, Adhemar showed great zeal for the crusade (there is evidence that Urban II had conferred with Adhemar before the council). Adhemar was named apostolic legate and appointed to lead the crusade by Pope Urban II on 27 November 1095. In part, Adhemar was selected to lead because he had already undertaken a pilgrimage to Jerusalem in 1086 and 1087. Following the announcement of the Crusade Adhemar spent the next year raising money and recruiting men.
