255. Pius IX

9 questions · Religion & Belief

Pius IX reigned in the 19th century and to this day holds the record for the longest pontificate in history: almost 32 years. His reign saw profound upheavals for the church. At the First Vatican Council he convened, the dogma of papal infallibility was proclaimed in 1870: in solemn doctrinal decisions on faith and morals, the pope cannot err. At the same time Pius lost worldly power: in the course of Italian unification the Papal States were dissolved and Rome became the capital of Italy. The pope withdrew as the "prisoner in the Vatican". Pius IX thus shaped the transition from a worldly ruling papacy to a purely spiritual one. Good to know: With almost 32 years in office, Pius IX had the longest pontificate in Church history (after Peter). In 1869/70 he convened the First Vatican Council. In 1870 that council proclaimed the dogma of papal infallibility in matters of faith. That same year he lost the Papal States to newly unified Italy: the pope became the „prisoner in the Vatican“.
