1220 CE
King Frederick II confirms rights of independence to the German bishops (the Confoederatio cum principibus ecclesiasticis) in an attempt to secure the election of his 9-year-old son, Henry VII as King of Germany. 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. Llywelyn the Great, Welsh prince of Gwynedd, begins raiding Pembrokeshire to retake land that he accuses William Marshal (the Younger) of stealing. This also includes Wiston Castle.

Crime & Justice
Disasters & Accidents
- 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.
