Pope Clement XI (; ; 23 July 1649 – 19 March 1721), born Giovanni Francesco Albani, was head of the Catholic Church and ruler of the Papal States from 23 November 1700 to his death in March 1721. Clement XI was a patron of the arts and of science. He was also a great benefactor of the Vatican Library; his interest in archaeology is credited with saving much of Rome's antiquity. He authorized expeditions which succeeded in rediscovering various ancient Christian writings and authorized excavations of the Roman catacombs. Biography Early life Giovanni Francesco Albani was born in 1649 in Urbino to the Albani family, a distinguished family of Albanian origin in central Italy. His mother Elena Mosca (1630-1698) was a high-standing Italian of bergamasque origin, descended from the noble Mosca family of Pesaro. His father Carlo Albani (1623-1684) was a patrician. His mother descended in part from the Staccoli family, who were patricians of Urbino, in part from the Giordani, who were nobles of Pesaro. The original name of the Albani was Lazzi (Laçi) which they changed to Albani in memory of their origin. Francesco Albani funded an expedition in Albania to locate the exact settlement of his family's origins. In the final report, the two most probable locations which were presented to him were Laç near Lezhë and Laç near Kukës, both in northern Albania. Albani was educated at the Collegio Romano in Rome from 1660 onwards. He became a very proficient Latinist and gained a doctorate in both canon and civil law. He was one of those who frequented the academy of Queen Christina of Sweden. He would serve as a papal prelate under Pope Alexander VIII and was appointed by Pope Innocent XII as the Referendary of the Apostolic Signatura. Throughout this time, he also served as the governor of Rieti, Sabina and Orvieto. Cardinalate Pope Alexander VIII elevated him to the cardinalate in 1690 despite his protests and made him the Cardinal-Deacon of Santa Maria in Aquiro but he later opted for the Diaconia of San Adriano al Forno and later, as the Cardinal-Priest, for the titulus of San Silvestro in Capite. He was then ordained to the priesthood in September 1700 and celebrated his first Mass in Rome on 6 October 1700. Pontificate Election to the papacy After the death of Pope Innocent XII in 1700, a conclave was convoked to elect a successor.
