Sixth Crusade

Despite having minimal combat, the Sixth Crusade was a huge success for the crusaders. The Holy Roman Emperor Frederic II, who oversaw the campaign, was excommunicated at the time. Frederick II negotiated with the Egyptian sultan shortly after his arrival in the Holy Land, and he promised to deny Christians access to Jerusalem, Nazareth, Bethlehem, and other holy towns.

Jerusalem had been in Muslim rule since 1187 CE, but it was eventually retaken from them largely to Frederick's diplomatic abilities rather than any actual combat.

As a result, the Sixth Crusade succeeded in accomplishing peacefully what the earlier, brutal and violent Crusades had failed to do.
