The Crusades, Part 3.
A significant result of the First Crusade was the further alienation of the Eastern & Western Churches. The help provided Byzantium by the crusaders were not what The Emperor Alexius was looking for.
It also resulted in an even greater alienation of the Muslims than had been in place before. 200 years of Crusading rampages across the Eastern Mediterranean permanently poisoned Muslim-Christian relations and ended the spirit of moderate tolerance for Christians living under Muslim rule. The only people who welcomed the crusaders were a handful of Christian minorities who’d suffered under Byzantine or Muslim rule; people like the Armenians and Lebanese Maronites. The Copts in Egypt saw the Crusades as a calamity. They were now suspected by Muslims rulers of holding Western sympathies while being treated as schismatics by the Western Church. Once the Crusaders took Jerusalem, they banned the Copts form making pilgrimage there.
