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.[17] 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.[17] These Christian defeats prompted the Third Crusade, which began two years after the Battle of Hattin.
