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.
Michelangelo dei Conti was born on 13 May 1655 in Poli, near Rome as the son of Carlo II, Duke of Poli, and Isabella d'Monti. Like Pope Innocent III (1198–1216), Pope Gregory IX (1227–1241) and Pope Alexander IV (1254–1261), he was a member of the land-owning family of the Conti, who held the titles of counts and dukes of Segni. He included the family crest in his pontifical coats of arms.
Pope Innocent III (Latin: Innocentius III; 1160 or 1161 – 16 July 1216) reigned from 8 January 1198 to his death. His birth name was Lotario dei Conti di Segni, sometimes anglicised to Lothar of Segni.
Pope Innocent was one of the most powerful and influential popes. He exerted a wide influence over the Christian regimes of Europe, claiming supremacy over all of Europe's kings. Pope Innocent was central in supporting the Catholic Church's reforms of ecclesiastical affairs through his decretals and the Fourth Lateran Council. This resulted in a considerable refinement of Western canon law. Pope Innocent is notable for using interdict and other censures to compel princes to obey his decisions, although these measures were not uniformly successful. Innocent called for Christian crusades against Muslim Spain and the Holy Land, as well as the Albigensian Crusade against the Cathars in southern France.
One of Pope Innocent's most critical decisions was organizing the Fourth Crusade. Originally intended to attack Jerusalem through Egypt, a series of unforeseen circumstances led the crusaders to Constantinople, where they ultimately attacked and sacked the city (1204). Innocent reluctantly accepted this result, seeing it as the will of God to reunite the Latin and Orthodox Churches, but it poisoned relations between the two churches.
