## Events
### By place
#### Fifth Crusade

* July – The Crusaders, led by the Knights Hospitaller, raid Burlus, located in the Nile Delta in Egypt. The town is pillaged, but the knights are ambushed on their return, and several Hospitallers, including Grand Master Guérin de Montaigu, are captured. Meanwhile, Sultan Al-Kamil sends an Egyptian squadron down the Rosetta branch of the Nile. It sails to Cyprus, where it finds a Crusader fleet lying off Limassol. During the attack, they sink and capture all the ships, taking many thousands of prisoners.
* Summer – The Crusader army is trapped by a Nile flood at Damietta. Cardinal Pelagius sends a Venetian squadron to intercept the Egyptian fleet, and attacks the harbours of Rosetta and Alexandria, but to no effect. Lack of money prevents Pelagius from building a sufficient number of ships, and the papal treasury can not spare him anymore. In September more of the Crusaders return home.

#### Mongol Empire

* Spring – The Mongol army (some 100,000 men) led by Genghis Khan crosses the Kyzylkum Desert – a freezing sand-and-tussock wilderness of some 450 kilometers – towards Bukhara. Meanwhile, Muhammad II, ruler of the Khwarazmian Empire, prepares a strong defense around his capital Samarkand. In February, Genghis approaches Bukhara, which is defended by a garrison of some 20,000 men, and begins the Siege of Bukhara. The city leaders open the gates to the Mongols, but Turkish forces who defend the city's citadel hold out for another twelve days. In a speech at the city's Friday Mosque, Genghis declares "I am the punishment of God."
* March – Mongol forces led by Genghis Khan besiege Samarkand, the city is defended by some 40,000 men, including a brigade of 20 war elephants. On the third day, the garrison launches a counter-attack, the defenders sent out their elephants, which panic, turn and trample their own men before escaping onto the open plain. Muhammad II attempts to relieve Samarkand twice but is driven back. After a week, the remainder of the garrison surrenders. The city's inhabitants, numbering some 100,000 are enslaved or slaughtered.
* Summer – Muhammad II flees westwards across northern Iran, hoping to find safety in the rugged and isolated region of Mazandaran on the southern coast of the Caspian Sea. He is pursued by 20,000 Mongol forces led by Subutai and Jebe (the Arrow). Abandoned by the remnants of his panic-stricken troops, Muhammad seeks shelter on a small island near Astara. There he dies of pleurisy some weeks later. He is succeeded by his son Jalal al-Din Mangburni, who is forced to flee to India after the Mongol invasion (see 1219).
* Autumn – Genghis Khan moves against the wealthy city of Urgench. He is joined by his eldest son Jochi, now conqueror of half a dozen lesser towns who attacks it from the north. Despite a stout defense, the city is taken after a 5-months siege. The Mongols have to fight for Urgench street by street, razing many houses. Jochi is given the right to loot the city for himself, but prefers to negotiate with the locals to avoid property damage. This is refused by Genghis, who removes Jochi from command and appoints Ögedei instead.
* November – Genghis Khan dispatches his youngest son Tolui, at the head of an army (around 50,000 men), into the Khwarazmian province of Khorasan. His forces also include 300 catapults, 700 mangonels to discharge pots filled with naphtha, 4,000 storming-ladders, and 2,500 sacks of earth for filling up moats. Among the first cities to fall is Termez (captured after a two-day siege) and later Balkh.
