[2] As a reward for its assistance against the Turks, Pope Clement XI in 1708 raised the Chapel of the Royal Palace to Collegiate rank and associated with it three parishes in the dioceses of Bragança and Lamego.

Western Lisbon and metropolitan rights over Leiria, Lamego, Funchal and Angra, together with elaborate privileges and honours, were granted to the new patriarch and his successors.

To obviate the inconvenience of this arrangement Pope Benedict XIV (13 December 1740) united East and West Lisbon into one single archdiocese under Patriarch Almeida, who ruled the see until his death in 1754.

At what date the patriarchs of Lisbon began to quarter the tiara with three crowns, though without the keys, on their coat of arms is uncertain and there are no documents referring to the grant of such a privilege.

By apostolic letters dated 30 September 1881 the metropolitan of Lisbon claims as suffragans the dioceses of Angola, St. James of Cape Verde, São Tomé, Egitan, Portalegre, Angra, and Funchal.
