Sixth Crusade
Overview
The Sixth Crusade was the outcome of Holy Roman Emperor Frederick II's long-delayed crusading vow. In 1225 Frederick married Isabella (Yolande), heiress of the Kingdom of Jerusalem, gaining a claim to the kingdom. When he set out in 1227 and turned back because of illness, Pope Gregory IX excommunicated him.
The excommunicated emperor reached the East in 1228 and chose negotiation with Sultan al-Kamil over war. Under the Treaty of Jaffa in February 1229, Jerusalem, Bethlehem and Nazareth were ceded to the Franks under a ten-year truce, while the Haram al-Sharif remained under Muslim control. Jerusalem was regained without bloodshed, but conflict between the emperor and local nobles turned into the War of the Lombards.
