Siege of Kiev

Ayyubids / Crusades

  • End of May / beginning of June: al-Adil II , Sultan of the Ayyubids in Egypt , is deposed and captured by his own ministers in a palace revolt. His half-brother al-Salih Ayyub is invited to take the throne.
  • Summer: As the new Egyptian sultan also claims rule over Damascus for himself, the local Sultan al-Salih Ismail and an-Nasir Dawud form an alliance with the crusade of the barons under Theobald von Champagne, which had arrived the previous year . They hand over Galilee to the Crusaders with several fortresses.
  • September: Theobald von Champagne, tired of the political turmoil in the Holy Land, starts his journey home to France with a large part of the crusade army after the end of his vow of commitment and after visiting the holy places in Jerusalem .
  • October 11th : A second crusade army from England under the leadership of Richard of Cornwall arrives in Acre.
  • End of the year: Since the alliance with the Crusaders met with widespread rejection in the Arab world and large parts of the troops refused to fight alongside the Christians against Ayyub in Egypt, the Crusaders concluded a neutrality agreement with as-Salih Ayyub. In it all areas west of the Jordan via Jerusalem to Ascalon are given to them.
  • The Coptic Egyptian scribe 'Abul Fada'il Ibn al-'Assal records the Fetha Negest code in writing. The author uses some apostolic writings for his laws and also earlier legal texts of Byzantine rulers.
