Pope Innocent XIII (Latin:Innocentius XIII; 13 May 1655 – 7 March 1724) was born as Michelangelo dei Conti and was Pope from 8 May 1721 to his death in 1724. He is the last pope to date to take the pontifical name of "Innocent" upon his election.

Pope Innocent XIII was reform-oriented, and he imposed new standards of frugality, abolishing excessive spending. He took steps to finally end the practice of nepotism by issuing a decree which forbade his successors from granting land, offices or income to any relatives - something opposed by many cardinals who hoped that they might become pope and benefit their families.
