Giulio Gabrielli was an Italian Catholic Church's cardinal. He spent most of his career in the Roman Curia. Gabrielli was born in Rome to a princely family originally from Gubbio in the Papal States. His parents were marquis Angelo Gabrielli and marquise Caterina Trotti-Bentivoglio, the most beautiful woman in the mid-18th century Rome, celebrated by Giacomo Casanova as the "marquise G.". He studied law at the Sapienza University of Rome and, while still a layman, was appointed Protonotary Apostolic, Relator of the Sacred Congregation of the Good Government and, in 1787, Secretary of the Sacred Congregation of the Tridentine Council. He was ordained priest only on March 23, 1800, but less than one year later Pope Pius VII elevated him to cardinal, in the consistory of February 23, 1801. He received the red hat on February 26 and the title of cardinal priest of San Tommaso in Parione on July 20. On January 11, 1808 he was consecrated bishop of Senigallia by Pius VII, in his private chapel. On March 26, 1808, following the retirement of cardinal Filippo Casoni, Pius VII appointed Gabrielli Cardinal Secretary of State. Considered as the most loyal guardian of the Church and the staunchest opponent of Napoleon and general de Miollis, on June 16 he was arrested by the French troops in his office at the Quirinal Palace in Rome and forced to move to Senigallia; he was later deported to Novara, and then to Milan. Two days after the arrest, he was replaced by cardinal Bartolomeo Pacca as pro-Secretary of State. In 1809 Gabrielli was eventually moved to France and confined in Sedan. In 1810 he was among the thirteen cardinals that refused to attend the ceremony of the marriage between Napoleon and Marie Louise of Austria, and were thus severely punished by the Emperor and forced to abandon their scarlet garments. In 1813 he joined Pius VII in his exile at Fontainebleau, and was one of the most influential personalities of the reconstituted papal court. The following year, in an attempt to subtract the pope from the influence of the cardinal, Napoleon decided to confine him again at Le Vigan, in the Cévennes region of southern France: here he was given hospitality by the vicomte Henri d'Alzon, the father of Fr. Emmanuel d'Alzon. In April 1814, after the abdication of Napoleon, he was liberated and returned to Rome, where the Pope appointed him Secretary of the Chancery of Apostolic Briefs and Prefect of the Sacred Congregation of the Tridentine Council. In 1816 he resigned the pastoral government of the diocese of Senigallia. In 1819 he became Cardinal Protoprete and consequently opted for the titulus of San Lorenzo in Lucina, that two centuries earlier had belonged to his forebear and namesake Giulio Gabrielli the Elder. In 1820 he resigned from Prefect of the Congregation of the Council and was appointed Pro-Datary of His Holiness. He also served as Cardinal Protector of the Order of Saint Augustine. Cardinal Gabrielli was considered as one of the most likely successors to Pius VII at the guide of the Church, but predeceased the Pope by less than one year. After a short illness, he died at his country villa in Albano Laziale, in the Castelli Romani area, in late Summer 1822. His body was exposed in the Palace of the Datary, and later in the basilica of Santa Maria sopra Minerva, where his funeral took place on October 1. He was buried in the Gabrielli chapel in that same church. His brother, prince Pietro Gabrielli was a notable supporter of Napoleon and during the French occupation of the Papal States served as deputy mayor of Rome. Prince Mario Gabrielli, son of prince Pietro and nephew of cardinal Giulio, married in 1815 Charlotte Bonaparte, elder daughter of Lucien Bonaparte and niece the Emperor.
