Some of his relatives fled to Egypt and the Rum-Seljuks, helping those lands with claims for the Caliph title. Still some things happened as OTL: 1244, Jerusalem was conquered by sultan as-Salih. (This was expectable, since the city lacked the hinterland for a better defense.) The only difference to OTL was that he used Mamluk soldiers for the attack instead of hired Choresmians. The city was damaged less than IOTL. 1248-54, the Europeans made the Sixth Crusade against Egypt, which stayed without success."@en . . . .
