At the death of Saladin the Crusader kingdom has been reduced to a narrow strip of land and a handful of ports. A fourth crusade never reaches the Holy Land, setting its sights instead on Constantinopole. One crusade after naother is launched to shore up the faltering crusader territories. But finally the crusader settlers are evicted by the Mamluks in 1291. Through the eyes of Mongols, Mamluks and the beleaguered Crusaders we will witness the collapse of an empire of faith.
