Pope Pius XI

Achille Ratti (born 31 May 1857) served as head of the Holy See and sovereign of the Vatican City from 1922 until his death in 1939. His pontificate intersected with major twentieth‑century events including the aftermath of World War I, the rise of Fascism, Nazism, and Soviet Union policies, and evolving relations between the Roman Catholic Church and modern nation‑states. He issued influential encyclicals and concordats while directing the Church's global missions and institutional reforms.

Early life and priesthood

Achille Ratti was born in Desio, then part of the Kingdom of Lombardy–Venetia within the Austrian Empire. He studied at the Minor Seminary of Seveso and the Seminary of Milan before attending the Pontifical Gregorian University and the University of Pavia, where he engaged with scholarship related to Manuscript studies, Librarianship and History. Ordained a priest in 1875, he served in parish work in the Archdiocese of Milan and later became a librarian at the Ambrosian Library and the Vatican Library, interacting with figures connected to the Accademia dei Lincei, the Italian unification debates, and bibliographic networks tied to Oxford University and the Biblioteca Apostolica Vaticana.

Episcopate and diplomatic career

In 1919 Ratti was appointed Bishop of Como and shortly thereafter was sent by Pope Benedict XV to Poland as Apostolic Visitator and then Apostolic Nuncio to the newly reconstituted Second Polish Republic, liaising with the Polish–Soviet War aftermath, the League of Nations era diplomacy, and Polish statesmen including Józef Piłsudski and Ignacy Paderewski. He negotiated concordats and addressed disputes involving the Holy See, the German Empire aftermath, the Austrian First Republic, and minority issues tracing to the Treaty of Versailles and the Treaty of Saint-Germain-en-Laye. His diplomatic work brought him into contact with Vatican Secretariats, the Congregation for Extraordinary Ecclesiastical Affairs, and European bishops navigating postwar territorial realignments.

Election to the papacy and coronation

Following the death of Pope Benedict XV in 1922, the College of Cardinals assembled in the Conclave of 1922 at the Apostolic Palace and elected Achille Ratti as pope on 6 February 1922. His election succeeded pontificates that had contended with World War I disruptions, the 1917 Code of Canon Law context, and the rise of ideological movements such as Bolshevism and Italian Fascism. The coronation and assumption of papal authority involved interactions with representatives from states including the Kingdom of Italy, the French Third Republic, the United Kingdom, and the United States diplomatic corps.

Major policies and encyclicals

The pope promulgated key encyclicals addressing theology, social doctrine, and international affairs. He issued encyclicals such as Mit brennender Sorge (targeting Nazi Germany policies and Hitler's regime), Quadragesimo Anno (addressing social order in the wake of Great Depression dynamics and referencing Rerum Novarum by Pope Leo XIII), and Casti Connubii (on matrimonial doctrine in the context of modern debates influenced by proponents linked to eugenics and secular Legislation trends). These documents engaged with economic thinkers associated with Keynesian economics discussions, jurists from the Roman Rota, and theologians connected to the University of Louvain and the Catholic University of America.

Relations with totalitarian regimes

His pontificate navigated concordats and confrontations with European regimes. He signed the Lateran Treaty and concordat with the Kingdom of Italy and Benito Mussolini's National Fascist Party, resolving the Roman Question and establishing Vatican City State sovereignty. He later condemned elements of Nazism in Germany and tried to protect Catholics under Third Reich policies, criticizing racially motivated laws and state interference in ecclesiastical affairs. In Spain he witnessed the tensions that preceded the Spanish Civil War, engaging with bishops from the Spanish hierarchy and taking positions amid anti‑clerical violence. He also expressed opposition to Communist anti‑religious campaigns in the Soviet Union and promoted solidarity with persecuted clergy in Mexico and France.

Church reforms and global outreach

He reorganized Roman Curia departments including the Congregation for the Propagation of the Faith and promoted missionary expansion in Africa, Asia, and Latin America, supporting institutes such as the Society of Jesus, the Pontifical Institute of Missionary Studies, and local episcopates in Brazil, Philippines, and China. He reformed seminarian formation linked to the Pontifical Lateran University and promulgated liturgical directives that affected the Roman Rite, catechesis promoted through the Congregation for the Clergy, and codification initiatives allied with canonists at the Vatican Secret Archives. He founded or endorsed institutions including the Papal Academy of Sciences and promoted Catholic participation in international bodies like the International Labour Organization and contacts with the Vatican Observatory.

Death and legacy

He died on 10 February 1939 in the Apostolic Palace shortly before the outbreak of World War II and was succeeded by Eugenio Pacelli (the next pope). His burial and memorials in the Vatican Grottoes prompted evaluations by historians of the Interwar period, scholars of Canon Law, and commentators in the Catholic press such as L'Osservatore Romano. Historians link his pontificate to debates over church‑state concordats, responses to Fascism and Nazism, and development of Catholic social teaching in the twentieth century. His papacy remains a subject of study in fields engaging with diplomatic history, ecclesiology, and the interaction between the Holy See and modern nation‑states.
