The Council of Clermont
27 Nov 1095 — Pope Urban II calls on Western knights to aid Eastern Christians and free Jerusalem, offering remission of sins. “God wills it,” the crowd answers. No one present imagines what they have started.
THE MOMENT IN CONTEXT
The crusade became possible because the Islamic Near East, which looked like a single vast enemy on the map, was in fact deeply divided against itself. Nominal authority lay with the Sunni Seljuk sultans, who ruled in the name of the Abbasid caliph in Baghdad, a figure by then reduced to a religious figurehead with little real power. Against them stood the Shia Fatimid caliphs of Egypt, regarded by the Seljuks as heretics rather than mere rivals, and between the two lay Syria, broken into quarrelling emirates. When the great sultan Malik-Shah died in 1092, his realm dissolved into a war of succession among his heirs. A united Islamic power could have crushed any Western expedition at the frontier, so the fracture of Seljuk authority was the precondition without which the First Crusade is difficult to imagine.
