The Siege of Acre was the first significant counterattack by King Guy of Jerusalem against Saladin, leader of the Muslims in Syria and Egypt. This pivotal siege formed part of what later became known as the Third Crusade. The siege lasted from August 1189 until July 1191, in which time the city's coastal position meant the attacking Latin force were unable to fully invest the city and Saladin was unable to fully relieve it with both sides receiving supplies and resources by sea. Finally, it was a key victory for the Crusaders and a serious setback for Saladin's ambition to destroy the Crusader States.

The Battle of Cresson was a small battle, fought on 1 May 1187 at the springs of Cresson, or 'Ain Gozeh, near Nazareth. It was a prelude to the decisive defeat of the Kingdom of Jerusalem at the Battle of Hattin two months later.

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 Kurûn Hattîn.

The Siege of Jerusalem was a siege on the city of Jerusalem that lasted from September 20 to October 2, 1187, when Balian of Ibelin surrendered the city to Saladin. Earlier that summer, Saladin had defeated the kingdom's army and conquered several cities. The city was full of refugees and had few defenders, and it fell to the besieging armies. Balian bargained with Saladin to buy safe passage for many, and the city came into Saladin's hands with limited bloodshed. Though Jerusalem fell, it was not the end of the Kingdom of Jerusalem, as the capital shifted first to Tyre and later to Acre after the Third Crusade. Latin Christians responded in 1189 by launching the Third Crusade led by Richard the Lionheart, Philip Augustus, and Frederick Barbarossa separately. In Jerusalem, Saladin restored Muslim holy sites and practiced tolerance toward Christians.
The Siege of Kerak took place in 1183, with Saladin's forces attacking and being repelled from the Crusader stronghold.

The Siege of Tyre took place from November 12, 1187 to January 1, 1188. An army commanded by Saladin made an amphibious assault on the city, defended by Conrad of Montferrat. After two months of continuous struggle, Saladin dismissed his army and retreated to Acre.

The Third Crusade (1189–1192) was an attempt by the leaders of the three most powerful states of Western Christianity to reconquer the Holy Land following the capture of Jerusalem by the Ayyubid sultan Saladin in 1187. It was partially successful, recapturing the important cities of Acre and Jaffa, and reversing most of Saladin's conquests, but it failed to recapture Jerusalem, which was the major aim of the Crusade and its religious focus.
