Editing Sixth Crusade (section)

=== Agreement of San Germano ===
The Agreement of San Germano of 25 July 1225, signed at present day [[Cassino]], was between Frederick II and Honorius III. A Dominican named [[Guala de Roniis]] was responsible for the negotiations. Frederick promised to depart on the Crusade by 15 August 1227 and remain for two years. During this period, he was to maintain 1000 knights in Syria, provide transport for additional forces, and provide Rome with 100,000 ounces in gold in the care of Hermann of Salza, John of Brienne and the patriarch. These funds would be returned to the emperor once he arrived at Acre. If, for any reason (including his death), he did not arrive, the money would be employed for the needs of the Holy Land. He also promised that if he went on Crusade that he would lead. After the agreement was signed, Guala became [[Bishop of Brescia]]. Based on the terms of the agreement, Frederick's forces ceased to occupy portions of the [[Papal States|pontifical states]]. Moreover, all papal possessions in the [[Kingdom of Sicily]] were to be restored to the pope.{{sfn|Runciman|1954|pp=177–178|loc=The Emperor Frederick: San Germano}}

Frederick attested to the terms at the high altar with his hand on the Gospels. Apostolic legate [[Rainald of Urslingen]], the [[duke of Spoleto]], swore "on the soul of the emperor" that the agreement would be upheld under the pain of excommunication. In a letter to the pope, Frederick reiterated the terms and accepted the ban in the event the Crusade did not happen. He had committed himself beyond all retreat.{{sfn|Van Cleve|1969|pp=440–441|loc=Agreement of San Germano}}
