Answer:
One group, known as the “People’s Crusade,” reached as far as Constantinople before being annihilated by the Turks. In 1096, the main crusading force, featuring some 4,000 mounted knights and 25,000 infantry, began to move east. Led by Raymond of Toulouse, Godfrey of Bouillon, Robert of Flanders, and Bohemond of Otranto, the army of Christian knights crossed into Asia Minor in 1097.
