On 4 December 1110, Sidon was captured after the siege of Sidon, a decade after the First Crusade, by King Baldwin I of Jerusalem and King Sigurd I of Norway. It then became the center of the Lordship of Sidon, an important vassal-state of the Kingdom of Jerusalem. Saladin captured it from the Crusaders in 1187, but German Crusaders restored it to Christian control in the Crusade of 1197. It would remain an important Crusader stronghold until it was finally destroyed by the Ayyubids in 1249. In 1260, it was again destroyed by the Mongols led by Kitbuqa. The remains of the original walls are still visible.
