In abe the Mamelukes rule Egypt, but I think we have to rethink that. If the crusades were successful the Ayubids never came to power in Egypt, then the Mamelukes could not have taken over from the Ayubids. The Mamelukes could have made a coup against an other dynasty, but it was during the Ayubid era the meaning of the Mamelukes grew.
During the crusade the Fatmides rueld Egypt, but they wouldn't have been able to hold on to the power anyway. Also shiite is removed, and it would be easy to say that the shiite faith died with the Fatmides.
An interresting idea would be a crusader Egypt, developing very differnt from the other crusader kingdoms with high tolerance for moslems, some influences from the coptic faith, and the evolution of a heresy which could anger the rest of the catholic world. The civil war in Egypt could then be between Christians and Moslems, however Christian Egypt should be able to put itself under protection of The Caliphate against the "pure" Catholics.
Also there could be an eventchain making Egyptian- Nubian relations high, and a complicated chain of events making either Egypt inherit Nubia or reverse (think Swabia's "Where should I rule" events).
