The war of Saint-Sabas

The war of Saint-Sabas between Venice and Genoa begins. The two maritime republics have been in increasing competition with one another for a long time. The immediate trigger of the conflict is a dispute over the power of disposal over the Church of Saint-Sabas, which is located in the middle of Acre on the border between the Genoese and the Venetian quarters on a strategically important hill. The outbreak of fighting leads to the side of the barons and orders of knights for one of the sides. Although the Templars and Johanniter initially tried to mediate between the Italian republics, they quickly fell on opposing sides after realizing the inevitability of war. The Templars and with them the Teutonic Knights opted for Venice, the Johanniter and the city of Pisa for Genoa. In response to the news of the fighting in Acre, the city lord Philip of Montfort in Tire used the opportunity to drive the Venetians out of the city. In the county of Tripoli , which does not belong to the Kingdom of Jerusalem , the inflamed conflict is creating political waves. Count Bohemond VI. takes sides for Venice, whose vassals from Gibelet remember their Genoese origins and oppose their master. The only neutral authorities are the regent Plaisance of Antioch and the Seneschal Geoffroy de Sergines with his French knights in Acre.

Siege of Alamut
  • November 19 : The Mongols under Prince Hülegü besiege and conquer the fortress of Alamut , breaking the rule of the assassins . Their ruler Rukn ad-Din Churschah has to submit to the Mongol Khan in public. After the city was taken, the defenders were gutted and, among other things, the library with valuable scientific and medical works was destroyed.
  • The Mongols arrive in Mesopotamia and destroy the Sumerians' irrigation systems, which are over 4,000 years old, so thoroughly that the population drops from 25 to around 1.5 million people within a comparatively short period of time. The plants will never be rebuilt.
