Saladin accepting the surrender of Guy de Lusignan after the Battle of Hattin in 1187,...

The Battle of Hattin took place on July 3 and 4, 1187, between the Crusader Kingdom of Jerusalem and the forces of the Kurdish Ayyubid sultan Salah ad-Din, known in the West as Saladin. It is also known as the Battle of the Horns of Hattin, from a nearby extinct volcano. 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, Islamic forces once again became the eminent military power in the Holy Land, re-conquering Jerusalem and several other Crusader-held cities. These Christian defeats prompted the Third Crusade, which began two years after the Battle of Hattin.
