## Events
### 1220
#### 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.

#### By place
###### Byzantine Empire

* November – Emperor Theodore I Laskaris dies after a 16-year reign and is succeeded by his son-in-law John III Doukas Vatatzes. John fends off Theodore's brothers, who believe that they have the better claim for the throne of the Empire of Nicaea. In December, he becomes the sole ruler, and during his reign, the Empire becomes the most powerful of the Byzantine successor states and the frontrunner in the race to recover Constantinople from the Latin Empire. John also cultivates a close relationship with Frederick II, Holy Roman Emperor, and negotiates with Pope Honorius III about the possibility of reuniting the Church.

###### Fifth Crusade

* June – Sultan Al-Kamil again offers peace terms to Cardinal Pelagius with the cession of Jerusalem and all Palestine apart from Oultrejordain, together with a 30 years' truce and money compensation for the dismantling of Jerusalem. Meanwhile, a German contingent under Louis I of Bavaria arrives at Damietta, with orders from Frederick II not to launch an attack on Cairo until the emperor's arrival. Louis and Pelagius decide to advance into Egypt towards Mansoura, where Al-Kamil has built a fortress to protect Cairo. The Crusaders assemble their armies and tents are set up just up the Nile, on June 29.
* 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.
* 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.
* August 26–28 – Battle of Mansoura: The Crusader army led by Pelagius and John I of Jerusalem is defeated by the Egyptian forces at Mansoura. John and the military orders fight a last stand on the river banks of the Nile. He beats off a Nubian assault (supported by elite Turkish cavalry) and drives them back, but only after thousands of soldiers have perished. The remaining Crusaders are surrounded by Al-Kamil's forces and begin a desperate retreat to Damietta. The city is well-garrisoned and supplied with arms; a naval squadron under Henry, Count of Malta ("Enrico Pescatore") defends the harbour against the Egyptians. The Crusaders retreat under cover of darkness. Many of the soldiers cannot bear to abandon their stores of wine, and drink them all rather than leave them. The Teutonic Knights set fire to the stores that they cannot carry, thus informing the Egyptians that they are abandoning their positions. In the meantime, Al-Kamil orders opening of the sluices along the right bank of the Nile, flooding the area. Pelagius on his ship is carried by the floodwaters past the blockading Egyptian fleet. Other ships, carrying the medical supplies of the army and much of its food, escape, but many are captured.
* 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.

###### Mongol Empire

* Spring – Genghis Khan orders an armed reconnaissance expedition into the Caucasus (consisting of Georgia and Armenia) under the command of Subutai and Jebe ("the Arrow"). The Mongols defeat two Georgian armies around Tbilisi, but lack the will or equipment to besiege the capital city. During the fighting, King George IV of Georgia himself is severely wounded and his elite knights are massacred. The Mongols then return to Azerbaijan and Persia, and burn and pillage a few more cities.
* 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.
* September – Battle of Parwan: Sultan Jalal al-Din Mangburni recruits an army of Turkic and Afghan warriors numbering some 60,000 men. As soon as news of this reaches Genghis Khan he sends a Mongol army of 30,000 men, led by his stepbrother Shikhikhutug. Meanwhile, Jalal al-Din moves to Parwan (modern Afghanistan), where the two armies meet in a narrow valley. Jalal al-Din takes the initiative, ordering his right-wing of Turks to dismount and engage in a skirmish. On the third day, the Mongols are finally defeated by the Khwarezmian forces and are forced to retreat. Shikhikhutug is driven off in defeat, losing over half his army.
* October – The Mongol army raids Georgia for the second time, and Subutai and Jebe allow their forces to pass through the Caucasus Mountains.
* 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.

* Spring – The Polovtsian army assembles on the Terek River lowlands and are joined by Alan, Circassian, and Don Kipchak/Cuman forces. The Mongol army crosses the Caucasus Mountains, but is trapped in the narrow mountain passes. The Mongol generals Subutai and Jebe (the Arrow) send an embassy to the Polovtsians and convince them to break their alliance with the Caucasian peoples. The Mongol cavalry invades the Caucasus region and devastates the local villages, seizing slaves, cattle and horses.
* The Mongol army invades Polovtsian territory and defeats the Polovtsians in a great battle near the Don River. Several Polovtsian leaders are killed – while the remainder flees westwards, across the Dnieper River, to seek support by various Russian princes. Steppe lands east of the Dnieper fall under Mongol control, Subutai and Jebe raise the wealthy city of Astrakhan on the Volga River. Subutai now parts his forces, he moves south to the Crimea (or Tauric Peninsula), while Jebe travels towards the Dnieper.
* Mongol forces capture the nominally Genoese trading outpost of Sudak, probably with the tacit approval of neighbouring rival Venetian outposts in the Crimea. Subutai promises to destroy any non-Venetian colonies in the area. In return, the Venetians provide Subutai with information about the kingdoms in Eastern Europe. Meanwhile, Köten Khan, Cuman/Kipchak chieftain of the Polovtsians, convinces Prince Mstislav Mstislavich of Galicia to form an alliance, and informs him of his plight against the Mongols.
* February – A council of Russian princes summons at Kiev; several princes are convinced by Köten Khan to assemble an allied army to drive the Mongols back. During the first half of March, Russian princes return to their principalities and begin to raise forces for the forthcoming campaign. The alliance has a combined force of some 60,000 men, mainly cavalry. Subutai unites his army with Jebe, and sends ambassadors to the Kievan Rus' princes, to tell them to stay out of the conflict as it didn't involve them.
* April – The Russian princes lead their separate armies from different parts of Russia, to assemble 60 kilometres downriver from Kiev. There are three main groups of princes taking part in the campaign; the Kievan army is represented by Grand Prince Mstislav Romanovich (the Old). The second group are the Chernigov and Smolensk armies under Prince Mstislav II. The third group is the Galician-Volhynian army under Mstislav Mstislavich with his son-in-law Daniel of Galicia, leaving from northern Ukraine.
* The Mongol leaders Subutai and Jebe receive news that Jochi, who camps north of the Caspian Sea, will not be able to provide the expected reinforcements due to Jochi's reported illness or suspected refusal to obey his father Genghis Khan's orders. Subutai sends an embassy to the Russian princes, to offer peace and perhaps attempt to break the Russian alliance with the Polovtsians. But the Mongol ambassadors are executed – a task eagerly carried out by Köten Khan's followers, by the end of April.
* Late April – The Russian and Polovtsian armies march down the west bank of the Dnieper River. Within a few days of the march beginning, a second group of Mongol ambassadors appear in the Russian camp and again offer peace. When their offers are rebuffed, the ambassadors are allowed to leave unharmed. Meanwhile, Russian forces from Galicia arrive by boat or cart-loads of equipment and food, along the Black Sea coast and up the Dnieper River, screened by Mongol forces on the east bank.
* Late May – The Mongol army under Subutai and Jebe establishes a defensive position on the Kalka River. Increasing disagreements amongst the Russian princes, about the wisdom of continuing to pursue the Mongols deeper into the steppes. By the end of May, the allied forces reach the banks of the Kalka River. The Polovtsian vanguard is way ahead of the rest of the Russian army, which gives them a triumphant feeling. Meanwhile, Subutai and Jebe set up a trap against the Russian forces.
* June – Mstislav Mstislavich escapes back to the Dnieper River with the remnants of his Galician army. Mstislav Romanovich (the Old) surrenders and is executed. According to sources, he and other Russian nobles are slowly suffocated to death during a Mongol 'drunken feast', they are tied up and laid flat on the ground beneath what is described as a wooden 'bridge' (or platform), on which Subutai, Jebe and their officers feast. This is revenge for killing the Mongol ambassadors.
* Battle of Samara Bend: A Volga-Bulgarian army under Ghabdula Chelbir defeats the Mongols, probably led by Subutai, Jebe and Jochi. The Bulgars retreat during the battle but the Mongols pursue them. Then the main Bulgar forces ambush the Mongols. Subutai and Jebe retreat their forces near the city of Sarai (future capital of the Golden Horde), not far from where the Volga River empties into the Caspian Sea.
* Autumn – Mongol forces under Jochi, Subutai and Jebe attack and defeat the Qangl Turks (eastern Kipchaks or Wild Polovtsians), killing their ruler. During the winter, they continue eastwards across the Great Steppe. Jebe (possibly poisoned) suddenly dies of a fever near the Imil River.
