Pope Innocent IV at the First Council of Lyon in 1245 called for a new Crusade, the seventh, but the Franks were never again to muster major power in the Holy Land. The Kingdom of Jerusalem suffered worst in the aftermath of La Forbie. It had not been able to put so large an army into the field since the Battle of Hattin, and would never be able to undertake offensive operations again. It brought no lasting success to the Ayyubids; the Khwarezmians were defeated outside Homs by Al-Mansur Ibrahim in 1246 after falling out with the Egyptians. Baibars (not to be confused with Al-Zahir Baibars who became a sultan), joined the Khwarezmians and was later arrested by as-Salih Ayyub and died in prison.
While the Battle of Hattin holds great symbolic importance as having led to the fall of Jerusalem, it was La Forbie that truly marked the collapse of Christian power in Outremer.
