First Crusade (Ard Marjhoola)

The First Crusade was a conflict between the Papacy and its allies (namely the Normans but with other volunteers across Europe) against Fatimid Caliphate advances. It was the first conflict in which joint Christian force counter attacked Muslim advances into Europe formally in the sake of religion.

While the Papacy were successful in driving the Fatimids back and preventing further raids as far as the Papal States, the Fatimids were still further up the Italian mainland than before Pope Benedict VIII's and his predecessor Pope Gregory VI's reign
