Praedecessores nostros was a papal encyclical written by Pope Pius IX on March 25, 1847, to address the crisis of the Great Irish Famine that occurred approximately between 1845 and 1850. This event is known by many as the 19th century’s greatest natural disaster. Pope Pius IX was born Giovanni Maria Mastai-Ferretti on May 13, 1792, in Senigallia, Italy. He studied at the College of Volterra in Tuscany and was ordained as a priest in 1819. Throughout the span of his life, Pius IX served as the director of the Roman hospice of San Michele, Bishop of Imola, and Archbishop of Spoleto. He was made a Cardinal in 1840 and elected Pope in 1846. Several important events that occurred during the papacy of Pius IX are the unification of Italy, the First Vatican Council, the defining of the dogma of the Immaculate Conception, and 38 papal encyclicals. Praedecessores nostros is one of the more significant papal decrees of the time because it addresses one of the most well known events in history. The Great Irish Famine was caused by the mysterious fungus, Phytophthora infestans. The fact that the potato was the staple food of over half the population of Ireland caused approximately one million people to die as a consequence.
During the pontificate of Pope Pius XI (1922–1939), the Weimar Republic transitioned into Nazi Germany. In 1933, the ailing President von Hindenburg appointed Adolf Hitler as Chancellor of Germany in a Coalition Cabinet, and the Holy See concluded the Reich concordat treaty with the still nominally functioning Weimar state later that year. Hoping to secure the rights of the Church in Germany, the Church agreed to a requirement that clergy cease to participate in politics. The Hitler regime routinely violated the treaty, and launched a persecution of the Catholic Church in Germany.
The theology of Pope Pius IX championed the pontiff's role as the highest teaching authority in the Church.
