Pope Pius XI was born on May 31, 1857 in Austria. He died on Feb 10, 1939 (age 81). Served as the leader of the Catholic Church from 1922 until his death in 1939, during which time he was responsible for fostering and completing an unprecedented number of concordats.
At the Gregorian University in Rome, he studied philosophy, canon law, and theology to earn his doctorates in each of those fields. He was instrumental in the creation of the Lateran Treaty, which served to end hostilities between the Catholic Church and the government of Italy. In Milan, his father ran a silk mill that the family owned.
Pope Pius XI wrote a number of books during his lifetime, the most notable of which is probably his encyclical Quadragesimo anno. This document, released in 1931, laid out the Pope’s social teachings and was widely influential at the time. Other books written by Pius XI include Iniquis afflictisque (1926), an encyclical on the persecution of the Church in Mexico, and Acerba animi (1929), a collection of speeches and writings on various topics.
