The official start date was set as August 15, 1096. Those armies that left before that time are considered part of the People's Crusade. Three of these armies never made it past Hungary; two others (under Peter the Hermit and Walter Sansavoir) were defeated by Kilij Arslan of Nicaea. Traditionally, the First Crusade deals with those who left after that official start date. As with the People's Crusade, these crusaders did not form one unified army.
In 1244, Egypt attacked Jerusalem. Louis IX of France started a crusade against Egypt from 1248 to 1254. It was a failure, and Louis spent much of the crusade living in Acre. In the midst of this crusade was the first Shepherds' Crusade in 1251.he Fourth Crusade was started by Pope Innocent III in 1202, with the idea to attack the Holy Land through Egypt. The Venetians changed this crusade, and went to the Christian city of Constantinople, where they attempted to place a Byzantine exile on the throne.
