Clement X

Pope Clement X (Latin: Clemens X; Italian: Clemente X; 13 July 1590 – 22 July 1676), born Emilio Bonaventura Altieri, was head of the Catholic Church and ruler of the Papal States from 29 April 1670 to his death on 22 July 1676.

Emilio Bonaventura Altieri, born in Rome in 1590, belonged to the Papal nobility. He received a doctorate in law and held various positions within the Catholic Church, including Bishop of Camerino and Superintendent of the Papal Exchequer. At the age of almost 80, he was elected Pope Clement X in 1670 after a four-month-long conclave. As Pope, he canonized and beatified various saints, promoted good relations between Christian countries, and made efforts to preserve the Altieri family name by adopting the Paoluzzi family. He also established a new tax in Rome, which led to conflicts with ambassadors and cardinals. Clement X celebrated the fourteenth jubilee of the holy year in 1675 despite his old age. During his pontificate, he created 20 cardinals, including Pietro Francesco Orsini, who later became Pope Benedict XIII.
