Innocent III called for another Crusade at the Fourth Lateran Council

Innocent III called for another Crusade at the Fourth Lateran Council. In the papal bull Quia maior he codified existing practice in preaching, recruitment, and financing the Crusades. A force—primarily raised from Hungary, Germany, Flanders—led by King Andrew II of Hungary and Leopold VI, Duke of Austria achieved little in what is categorized as the Fifth Crusade. The strategy was to attack Egypt because it was isolated from the other Islamic power centers, it would be easier to defend, and was self-sufficient in food.
