Levant edit

  • Autumn – Frederick II appoints Marshal Richard Filangieri as his imperial legate, and sends an expeditionary army of mostly Lombards for the defense of Jerusalem. He gathers some 600 knights, 100 "sergeants-at-arms", 700 armed infantrymen, and 3,000 marines. The army is supported by 32 war-galleys.[6]
  • War of the Lombards: Richard Filangieri sails for Beirut, where the town is handed over to him. He occupies Sidon and Tyre – while other Lombard forces appear before Acre. At Acre, Filangieri summons a meeting of the High Court and shows letters from Frederick II appointing him as ambassador (baili).[7]

China edit

  • April 9 – A huge fire breaks out at night in the southeast of Hangzhou during the Song dynasty. Fighting the flames is difficult due to limited visibility. When the fires are extinguished, it is discovered that an entire district of the city (some 10,000 houses) has been consumed by the flames.

Mongol Empire edit

  • August – Ögedei Khan orders the invasion of Korea. A Mongol army crosses the Yalu River and quickly secures the surrender of the border town of Uiju. The Mongols are joined by Hong Bok-won, a Goryeo general, who takes their side with his subordinates numbering some 1500 families.[8]
  • Siege of Kuju: Mongol forces besiege the city of Kuju. They deploy assault teams who man siege towers and scale ladders. Despite the fact the Goryeo army is heavily outnumbered, the garrison refuses to surrender.
