Pope Clement IX

Pope Clement IX (Latin: Clemens IX; Italian: Clemente IX; 28 January 1600 – 9 December 1669), born Giulio Rospigliosi, was head of the Catholic Church and ruler of the Papal States from 20 June 1667 to his death in December 1669.

Giulio Rospigliosi was born into the noble Rospigliosi family in 1600 and studied at the Seminario Romano and the University of Pisa. He held various positions in the Church, including Titular Archbishop of Tarsus and Apostolic Nuncio to Spain. As a man of letters, he wrote poetry, dramas, and libretti, and was a patron of the artist Nicolas Poussin.

Appointed as a cardinal by Pope Alexander VII, Rospigliosi was elected as Pope Clement IX in 1667. His pontificate was marked by mediation during European wars, and his popularity in Rome stemmed from his charity, humility, and refusal to advance his family's wealth. He beatified Rose of Lima and canonized Mary Magdalene de' Pazzi and Peter of Alcántara, while also creating 12 new cardinals.

Clement IX was a patron of the arts, commissioning works from Gian Lorenzo Bernini and opening the first public opera house in Rome. He attempted to strengthen Venetian defenses against the Turks in Crete, but was unsuccessful in gaining wider support. In 1669, after learning about the Venetian fortress of Candia surrendering to the Turks, Clement IX fell ill and died.

Giulio Rospigliosi was born in 1600 to the Rospigliosi family, a noble family of Pistoia in the Grand Duchy of Tuscany to Giacomo and Caterina Rospigliosi. He studied at the Seminario Romano and later at the University of Pisa as a pupil of the Jesuits, receiving doctorates in theology, philosophy and both canon and civil law in 1623. After receiving his doctorates, he taught theology there as a professor from 1623 to 1625.

Later Rospigliosi worked closely with Pope Urban VIII (1623–1644) where he worked in the diplomatic corps as the Referendary of the Apostolic Signatura. He was appointed as the Titular Archbishop of Tarsus in 1644 and later received episcopal consecration in the Vatican. Rospigliosi also served as the Apostolic Nuncio to Spain from 1644 until 1653 when he decided to retire from that post. He lived in retirement throughout the pontificate of Pope Innocent X who disliked and distanced himself from those associated with his predecessor. He was also made vicar of Santa Maria Maggiore in Rome.

Rospigliosi was an accomplished man of letters who wrote poetry, dramas and libretti, as well as what may be the first comic opera, namely his 1637 libretto Chi soffre, speri. He was also a patron of Nicolas Poussin, commissioning A Dance to the Music of Time from him and dictating its iconography.

Pope Alexander VII appointed him to the cardinalate in 1657 as the Cardinal-Priest of San Sisto Vecchio and was also appointed as the Cardinal Secretary of State in 1655 which he held until 1667.
