The following is an overview of the armies of First Crusade, including the armies of the European noblemen of the "Princes' Crusade", the Byzantine army, a number of Independent crusaders as well as the People's Crusade and the subsequent Crusade of 1101 and other European campaigns prior to the Second Crusade beginning in 1147.
The total strength of the armies of the Princes' Crusade is estimated at 40,000, including 4,500 nobles.[1] It has been estimated that no more than 20% were non-combatants and a cavalry-to-infantry ratio of about one to seven,[2] for rough estimates of just below 5,000 cavalry and 30,000 infantry at the beginning of the expedition.
