Geopolitics & Diplomacy
- May 13 – Emperor Juntoku is forced to abdicate, and is briefly succeeded by his 2-year-old son Chūkyō on the throne of Japan. Ex-Emperor Go-Toba leads the unsuccessful Jōkyū War against the Kamakura shogunate.source
Conflict & Security
- February – The cities of Merv (perhaps the world's largest up to this date), Herat and Nishapur which have peacefully surrendered rise up in arms. Genghis Khan sends his son Tolui to spend an extra month to subdue the revolts. Contemporary scholars report over a million people are systematically killed in a genocide.source
- July 4 – Pelagius orders a three-days fast in preparation for the advance. King John I of Jerusalem arrives at Damietta to rejoin the Crusade at the command of Honorius III. The Crusader force moves towards Sheremsah, halfway between Faraskur and Mansoura on the east bank of the Nile, occupying the city on July 12. Sources tell of 630 ships of various sizes, 5,000 knights, 4,000 archers, and 40,000 men. A horde of pilgrims march with the army. They are ordered to keep close to the river, to supply the Crusaders with water. Pelagius plans a new offensive and leaves a large garrison at Damietta.source
- August 28 – Pelagius sues for peace and sends an envoy to Al-Kamil. The terms of surrender are accepted, which includes the retreat from Damietta – leaving Egypt with the remnants of the Crusader army and an 8-year truce. After prisoners are exchanged, Al-Kamil enters Damietta on September 8. The Fifth Crusade ends with nothing gained for the West, with much lost, men, resources and reputations. The Crusaders blame Frederick II for not being there. Pelagius is accused of ineffectual leadership and a misguided view, which has led to rejecting the sultan's peace offerings.source
- October – The Mongol army raids Georgia for the second time, and Subutai and Jebe allow their forces to pass through the Caucasus Mountains.source
- November 24 – Battle of the Indus: Left with some 20,000 men, Jalal al-Din Mangburni has headed for the Indus River where Genghis catches up with him. In a desperate battle the Khwarezmain forces are destroyed, completing the Mongol conquest of the Khwarazmian Empire, while Jalal al-Din flees across the river and escapes into India.source

- Siege of Tallinn: An Estonian Crusader army tries to conquer the Danish stronghold of Tallinn with the help of Revalians, Harrians and Vironians. They besiege the stronghold for 14 days but finally retreat their forces.source
Technology & Infrastructure
- July 24 – Pelagius moves the Crusader forces near Ashmun al-Rumman, on the opposite bank from Mansoura. Queen-Regent Alice of Cyprus and leaders of the military orders warn Pelagius of a large Muslim army being formed in Syria. Meanwhile, the Egyptian army under Al-Kamil crosses the Nile near Lake Manzaleh and establishes themselves between the Crusader camp and Damietta. In the Ushmum canal at Sheremsah, Al-Kamil's ships sail down the Nile and block the Crusaders' line of communications to Damietta. In August, Pelagius orders a retreat, but the route is cut off by Egyptians.source
