By place[edit]




  • October 10Richard of Cornwall, brother of King Henry III, arrives at Acre for a pilgrimage to Jerusalem. His pilgrimage has the approval of Emperor Frederick II – who is married to his younger sister, Isabella of England, and gives him the task to make arrangements with the Military Orders. On his arrival, Richard travels to Ascalon – where he is met by ambassadors from As-Salih Ayyub. As a negotiator, he is successful in the release of prisoners captured at Gaza (see 1239), and he also assists with the building of the citadel in Ascalon.[5]

Mongol Empire[edit]

  • Winter – The Mongols under Batu Khan cross the frozen Dnieper River and lay siege to the city of Kiev. On December 6, the walls are rendered rubble by Chinese catapults and the Mongols pour into the city. Brutal hand-to-hand street fighting occurs, the Kievans are eventually forced to fall back to the central parts of the city. Many people take refuge in the Church of the Blessed Virgin. As scores of terrified Kievans climb onto the Church's upper balcony to shield themselves from Mongol arrows, their collective weight strain its infrastructure, causing the roof to collapse and crush countless citizens under its weight. Of a total population of 50,000, all but 2,000 are massacred.[6]
