The fall of Edessa in 1144 led to a call for a new crusade by Pope Eugene III in 1145 and 1146. In the spring of 1147, the Pope also authorized a crusade in the Iberian peninsula, where "the war against the Moors had been going on for hundreds of years." Pope Eugene encouraged Marseilles, Pisa, Genoa, and other Mediterranean cities to fight in Iberia. He also authorized Alfonso VII of León and Castile to equate his campaigns against the Moors with the rest of the Second Crusade.
