The campaign took place in 1228 and was the first Crusade in Europe to have been launched without the direct support of the Papacy.
The Crusade came about as a result of Frederick’s promise to the Papacy that he would go on the crusade. However, differences with the Papacy led to Frederick’s excommunication in 1227.
Despite this, he launched the Sixth Crusade on his own in 1228 and set the precedent for crusading campaigns independent of the Pope.
Sixth Crusade Background
By the beginning of the 13th century, Jerusalem and other territorial gains made during early Crusades by the European armies had been lost.
At the time, the Ayyubids had control of the region, projecting influence from their power base in Egypt.
The Papacy encouraged the launch of the Fifth Crusade in 1213 but it didn’t alter European fortune in the Holy Lands. Almost immediately after the failure of the Fifth Crusade in 1221, the Pope began pushing for another military campaign to the Holy Lands.
However, he delayed any efforts to fulfill the pledge until 1227. By this time, he had a claim to the former Kingdom of Jerusalem through his marriage.
He consequently launched an initial military campaign in 1227 but was forced to give up the campaign due to an epidemic breakout. He launched the campaign again the next year and it came to be known as the Sixth Crusade.
Role of the Papacy
The Papacy had been the most potent organizers of religious crusades in Europe until at least the Fifth Crusade.
After the failure of the Fifth Crusade, the Papacy continued to push European kings and rulers to rally for another Crusade.
However, it was independent of this call that Frederick II decided to undertake the Sixth Crusade. In fact, Pope Gregory IX had excommunicated Frederick due to his failed campaign in 1227.
In 1228, Frederick launched the Sixth Crusade without the support of the Papacy.
This set the tradition that European monarchs and barons could launch Crusades without the express support of the reigning Pope.
Beginning of Sixth Crusade
Most of the soldiers and nobles fighting for the Sixth Crusade came from Frederick II’s Italian and German lands.
Frederick was consequently the undisputed leader of the Sixth Crusade and he set sail for Syria in 1228.
Before the Crusader fleet could reach the Holy Land, Frederick decided to make a stop at Cyprus where he aimed to reassert imperial authority. He did this by forcing the regent of Cyprus, John of the Ibelin faction, to give up his regency and accept Frederick’s authority.
By doing so, Frederick was able to temporarily establish direct control in Cyprus.
However, the imperial control on the island would be short-lived and yet it caused Frederick the loss of the support of the Ibelin faction.
Arrival in Holy Lands
When the army of the Sixth Crusade left Cyprus and reached Acre, they received a mixed response from the local population.
Due to Pope Gregory’s excommunication of Frederick and Frederick’s treatment of John of Ibelin, support for his Crusade had waned significantly.
This was especially so because Patriarch Gerald in Acre following Papal policy towards Frederick and refused to lend him support.
This effectively made it impossible for Frederick to amass a sufficient army and defeat the Muslim rule in Jerusalem.
He consequently decided to have the matter resolved diplomatically.
Frederick II could speak Arabic and maintain highly favorable opinion of the Saracens.
These both contributed significantly to the goodwill he was able to arouse in al-Kamil and his court.
Al-Kamil was also engaged in suppressing a rebellion in Syria at the time. So he took the opportunity to hand over Jerusalem and many neighboring territories to Frederick.
At the same time, Muslims retained control of the Temple Mount and other holy sites in the city.
The compromise effectively made it possible for Frederick to take control of Jerusalem and achieve the aims of the Sixth Crusade without any fighting at all.
