The Treaty of Devol made in 1108 codified what leader's defeat in the First Crusade?
Armies of Bohemond of Taranto The Armies of Bohemond of Taranto include a major component of the First Crusade under the leader Bohemond I of Antioch formed in 1097. He is regarded as the real leader of the First Crusade. He formed a second army in 1107 to defend Antioch but instead used it to attack the Byzantine emperor Alexios I Komnenos, resulting in the Treaty of Devol, codifying Bohemond’s defeat. Runciman estimates that the first army included 500 cavalry and 3500 infantrymen (plus clergy and non-combatants) and other estimates that the second army was at 34,000 personnel strength are likely greatly exaggerated.
Army of Hugh the Great on the First Crusade The Army of Hugh the Great on the First Crusade was formed after the Council of Clermont, led by Pope Urban II in November 1095. Hugh, son of Henry I, King of France, and his wife Anne of Kiev, was Count of Vermandois, "de jure uxoris", due to his marriage to Adelaide, Countess of Vermandois, daughter of Herbert IV, Count of Vermandois, and his wife Adele of Valois.
