The Maronites assisted the crusaders and affirmed their affiliation with the Holy See of Rome in 1182. To commemorate their communion, Maronite Patriarch Youseff Al Jirjisi received the crown and staff, marking his patriarchal authority, from Pope Paschal II in 1100 AD. In 1131, Maronite Patriarch Gregorios Al-Halati received letters from Pope Innocent II in which the Papacy recognized the authority of the Patriarchate of Antioch. Patriarch Jeremias II Al-Amshitti (1199–1230) became the first Maronite Patriarch to visit Rome when he attended the Fourth Council of the Lateran in 1215. The Patriarchate of Antioch was also represented at the Council of Ferrara in 1438.
