HATTIN, BATTLE OF

(July 4, 1187), battle in northern Palestine that marked the defeat and annihilation of the Christian Crusader armies of Guy de Lusignan, king of Jerusalem (reigned 118692), by the Muslim forces of Saladin. It paved the way for the Muslim reconquest of the city of Jerusalem (October 1187) and of the greater part of the three Latin StatesTripoli, Antioch, and Jerusalemthus nullifying the achievements made in the Holy Land by the leaders of the first Crusades and alerting Europe to the need for a third Crusade. In July 1187 the Crusaders were camped at Sepphoris, about 20 miles (32 km) west of the Sea of Galilee, when word reached them that Saladin had attacked the city of Tiberias along the lake. On July 3 about 15,000 Crusaders abandoned their camp to go to the relief of the besieged city. Their route took them through a hot, arid plain where, halfway to Tiberias, they ran out of water while under continual harassment from Saladin's cavalry. The Crusaders' condition worsened after a night spent without water, but the next morning they resumed their march, heading toward a range of hills above the village of Hattin. Confronted by Saladin's army, the Crusaders, who were no longer able to fight effectively, left the road and were driven back against the two largest hills, the Horns of Hattin, by the Muslims. There they suffered a decisive defeat at the hands of the 18,000-man Muslim army. Most of the Crusaders were slaughtered on the field, but Saladin spared the lives of King Guy and most of the Christian lords. On the day after the battle, Saladin launched his campaign to retake the city of Jerusalem.
