Well, I'm not that knowledgable on the subject. When I said the Crusades I was thinking of the invasion and occupation of 'The Holy Land'. I wasn't really thinking of the effort to drive invading Muslims out of Europe.
The effort to drive Moslems out of Europe has three threatres of operation. The one in the West was in Spain and it's called the Reconquista. The one in the South (since Moslems occupied Sicily, Corsica and several other islands) doesn't really have a name, but the Sutheastern French and Italian nobility managed to recover those islands, destroy the Cathers and drive the Angevenians into the sea. The third part of the war is called WWI. The Allies broke the back of the Ottoman Empire which allowed them to totally resolve the Greek Civil War and create Yugoslavia (for whatever purpose that served).
The Crusades focused on a single issue and that was to keep the right to undertake pilgrimages to the Holy Land.
