The patriarch and the masters of the military orders—[[Gerold of Lausanne|Gérold of Lausanne]], [[Pedro de Montaigu]] and [[Bertrand de Thessy]]—all felt betrayed by the treaty and its concessions making the protection of the Holy city near-impossible. [[Hermann von Salza|Hermann of Salza]] approached Gérold with a proposal of reconciliation, but the patriarch saw only deceit, trying to prevent Frederick's entry into Jerusalem by threatening excommunication of the army and placing the city under interdict. He sent archbishop [[Peter of Limoges (bishop)|Peter of Caesarea]] to meet the army, but he was too late.{{sfn|Runciman|1954|pp=187–188|loc=The Recovery of Jerusalem (1229)}}

Frederick entered Jerusalem on 17 March 1229 and received the formal surrender of the city by al-Kamil's agent. He went to the [[Church of the Holy Sepulchre]] the next day and placed the crown on his own head. Hermann of Salza read the emperor's statement, blaming his excommunication not on the pope, but his advisors. It is unknown whether he intended this to be interpreted as his official coronation as King of Jerusalem; the absence of the patriarch rendered it questionable. There is evidence to suggest that the crown Frederick wore was actually the imperial one, but in any case proclaiming his lordship over Jerusalem was a provocative act. Legally, he was actually only regent for his son with Isabella, [[Conrad IV of Germany|Conrad II of Jerusalem]], who had been born shortly before Frederick left in 1228. Conrad's maternal grandparents were [[Maria of Montferrat]] and [[John of Brienne]].{{sfn|Runciman|1954|pp=189–190|loc=Frederick at Jerusalem (1229)}}

Still wearing his crown, Frederick proceeded to the palace of the Hospitallers where he met with the English bishops and members of the military orders to discuss the fortifications of the city. Not until the morning of 19 March 1229 did Peter of Caesarea arrive to enforce the interdict, which he wisely chose not to do. At any rate, Frederick's interest in Jerusalem was waning, as he was planning to immediately leave. While Frederick was on his way to the harbour he was pelted with dung and entrails by the unappreciative people of Acre. [[Odo of Montbéliard]] and [[John of Ibelin, the Old Lord of Beirut|John of Ibelin]] quelled the unrest.{{sfn|Hardwicke|1969|p=545|loc=The Crowning of Frederick}}

On 1 May 1229, Frederick departed from Acre, landing at Cyprus to attend the wedding by proxy of [[Henry I of Cyprus]] to [[Alice of Montferrat]], with the bride later transported to Cyprus by the emperor's supporters. He arrived at [[Brindisi]] on 10 June 1229, and it was a month before the pope was aware that he had left the Holy Land. By the autumn, he had regained full possession of his empire. Frederick obtained from the pope relief from his excommunication on 28 August 1230 with the [[Treaty of San Germano]], and he returned to the Hospitallers and the Templars the goods confiscated in Sicily.{{sfn|Whalen|2019|pp=40–44|loc=A contested vow}}
