The Catholic diocese of Ceuta, first Portuguese and afterwards Spanish, existed from 1417 to 1879. It was a suffragan of the Patriarchate of Lisbon until 1675, with the end of the Iberian Union, when Ceuta chose to remain linked to the king of Spain. Since then it was a suffragan of the archdiocese of Seville. Its territory around Ceuta had previously belonged to the Order of Christ. The diocese of Tanger was united to it, in 1570. In 1851, upon the signature of the concordat between the Holy See and Spain, the diocese of Ceuta was agreed to be suppressed, being combined into the diocese of Cádiz y Ceuta (up to then diocese of Cádiz y Algeciras). The agreement was implemented in 1879. Ordinaries Diocese of Ceuta Erected: 4 April 1417 Metropolitan: Archdiocese of Seville Aymar de Aureliano, O.F.M. (21 Mar 1421 – 1443 Died) João Manuel, O.
