Battle of Hattin

The Battle of Hattin took place on 4 July 1187, between the Crusader states of the Levant and the forces of the Ayyubid sultan Saladin. It is also known as the Battle of the Horns of Hattin, due to the shape of the nearby extinct volcano of that name.

The Muslim armies under Saladin captured or killed the vast majority of the Crusader forces, removing their capability to wage war. As a direct result of the battle, Muslims once again became the eminent military power in the Holy Land, re-capturing Jerusalem and most of the other Crusader-held cities and castles. These Christian defeats prompted the Third Crusade, which began two years after the Battle of Hattin.

The battle took place near Tiberias in present-day Israel. The battlefield, near the village of Hittin, had as its chief geographic feature a double hill (the "Horns of Hattin") beside a pass through the northern mountains between Tiberias and the road from Acre to the east. The Roman road, known to the Arabs as Darb al-Hawarnah, served as the main east–west passage between the Jordan fords, the Sea of Galilee and the Mediterranean coast.

Guy of Lusignan became king of Jerusalem in 1186, in right of his wife, Sibylla, after the death of her son Baldwin V. The Kingdom of Jerusalem was divided between the "court faction" of Guy, consisting of Sibylla and relative newcomers to the kingdom such as Raynald of Châtillon, Gerard of Ridefort and the Knights Templar; versus the "nobles' faction", led by Raymond III of Tripoli, who had been a regent for the child-king Baldwin V and had opposed Guy's succession. Raymond III of Tripoli had supported the claim of Sibylla's half-sister Isabella and Isabella's husband, Humphrey IV of Toron, and led the rival faction to the court party. Open warfare was prevented only by Humphrey of Toron swearing allegiance to Guy, which ended the succession dispute. The Muslim chronicler Ali ibn al-Athir claimed that Raymond was in a "state of open rebellion" against Guy.

Saladin had become vizier of Egypt in 1169 and had taken Damascus in 1174 and Aleppo in 1183. He controlled the entire southern and eastern flanks of the crusader states and united his subjects under Sunni Islam, convincing them that he would wage holy war to push the Christian Franks from Jerusalem. Saladin often made strategic truces with the Franks when he needed to deal with political problems in the Muslim world, and one such truce was made in 1185.

In 1187 Raynald of Châtillon raided a Muslim Hajj caravan while the truce with Saladin was still in place. Saladin swore that he would kill Raynald for violating the truce. He sent his son Al-Afdal and the emir Gökböri to raid the Frankish lands surrounding Acre. Gerard de Ridefort and the Templars engaged Gökböri in the Battle of Cresson in May 1187 and were heavily defeated. The Templars lost around 150 knights and 300 foot-soldiers, who had made up a great part of the military of Jerusalem. Jonathan Phillips states that "the damage to Frankish morale and the scale of the losses should not be underestimated in contributing towards the defeat at Hattin".

In July, Saladin laid siege to Tiberias, where Raymond III's wife, Eschiva of Bures, was trapped. In spite of that, Raymond argued that Guy should not engage Saladin in battle and that Saladin could not hold Tiberias because his troops would not stand to be away from their families for so long. The Knights Hospitaller also advised Guy not to provoke Saladin.

Gerard de Ridefort however advised Guy to advance against Saladin, and Guy took his advice. Norman Housley suggests that that was because "the minds of both men had been so poisoned by the political conflict 1180-1187 that they could only see Raymond's advice as designed to bring them personal ruin" and also because he had spent Henry II of England's donations in calling the army and was reluctant to disband it without a battle. That was a gamble on Guy's part, as he had left only a few knights to defend the city of Jerusalem.
