This meant the crusading experience and ideology was far more pervasive than the 'Crusades', which were major expeditions launched with Papal support. French Catholic lawyer Étienne Pasquier (1529–1615), was one of the first to number them, a sequence that remains largely unchanged. The 1096-1099 First Crusade was succeeded by the Second (1146–1149), Third (1187–1192), Fourth (1198–1204), and Fifth (1217–1221). In 1228 to 1229, Frederick II, Holy Roman Emperor led the Sixth Crusade, with Louis IX of France commanding the Seventh (1248–1254), before dying in 1270 during the Eighth. The Western presence in Palestine ended with the loss of Acre in 1291.
