In 1099, the Fatimid ruler expelled the native Christian population before Jerusalem was besieged by the soldiers of the First Crusade. After taking the solidly defended city by assault, the Crusaders massacred most of its Muslim and Jewish inhabitants, and made it the capital of their Kingdom of Jerusalem. The city, which had been virtually emptied, was recolonized by a variegated inflow of Greeks, Bulgarians, Hungarians, Georgians, Armenians, Syrians, Egyptians, Nestorians, Maronites, Jacobite Miaphysites, Copts and others, to block the return of the surviving Muslims and Jews. The north-eastern quarter was repopulated with Eastern Christians from the Transjordan. As a result, by 1099 Jerusalem's population had climbed back to some 30,000.
