Pope Pius II

Pope Pius II (Latin: Pius PP. II, Italian: Pio II), born Enea Silvio Bartolomeo Piccolomini (Latin Aeneas Silvius Bartholomeus; 18 October 1405 – 14 August 1464) was Pope from 19 August 1458 to his death in 1464. He was born at Corsignano in the Sienese territory of a noble but decayed family. His longest and most enduring work is the story of his life, the Commentaries, which is the only autobiography ever written by a reigning pope. Before he was ordained priest, he also wrote a quantity of mildly pornographic poetry as well as a novel in much the same vein.

Early life

Aeneas was born to Silvio, a soldier, and Vittoria Forteguerri, who had 18 children in total, though most died. He grew up in Corsignano and left to study at the age of eighteen.

After studying at the universities of Siena and Florence, he settled in the former city as a teacher, but in 1431 accepted the post of secretary to Domenico Capranica, bishop of Fermo, then on his way to the Council of Basel (1431–39). Capranica was protesting against the new Pope Eugene IV's refusal of a cardinalate for him, which had been designated by Pope Martin V. Arriving at Basel after enduring a stormy voyage to Genoa and then a trip across the Alps, he successively served Capranica, who ran short of money, and then other masters.

Pope Pius XII

Pope Pius XII (Italian: Pio XII), born Eugenio Maria Giuseppe Giovanni Pacelli (Italian pronunciation: [euˈdʒɛːnjo maˈriːa dʒuˈzɛppe dʒoˈvanni paˈtʃɛlli]; 2 March 1876 – 9 October 1958), reigned as Pope from 2 March 1939 to his death in 1958. Before his election to the papacy, Pacelli served as secretary of the Department of Extraordinary Ecclesiastical Affairs, papal nuncio to Germany (1917–1929), and Cardinal Secretary of State, in which capacity he worked to conclude treaties with European and Latin American nations, most notably the Reichskonkordat with Nazi Germany, with which most historians believe the Vatican sought to protect the Church in Germany while Adolf Hitler sought the destruction of "political Catholicism". A pre-war critic of Nazism, Pius XII lobbied world leaders to avoid war and, as Pope at the outbreak of war, issued Summi Pontificatus, expressing dismay at the invasion of Poland, reiterating Church teaching against racial persecution and calling for love, compassion and charity to prevail over war.

Pope

The Pope (Latin: papa from Greek: πάππας pappas, a child's word for "father") is the Bishop of Rome and the leader of the worldwide Catholic Church. The primacy of the Roman bishop is largely derived from his role as the traditional successor to Saint Peter, to whom Jesus is supposed to have given the keys of Heaven and the powers of "binding and loosing", naming him as the "rock" upon which the church would be built. The current pope is Francis, who was elected on 13 March 2013, succeeding Benedict XVI.

The office of the Pope is the papacy. His ecclesiastical jurisdiction, the Diocese of Rome, is often called "the Holy See" or "the Apostolic See", the latter name being based upon the belief that the Bishop of Rome is the successor of Peter the Apostle. The Pope is considered one of the world's most powerful people because of his diplomatic and cultural influence. He is also head of state of Vatican City, a sovereign city-state entirely enclaved within the Italian capital city of Rome.

Pope Pius XI

Pope Pius XI, (Italian: Pio XI) born Ambrogio Damiano Achille Ratti (Italian pronunciation: [amˈbrɔdʒo daˈmjano aˈkille ˈratti]; 31 May 1857 – 10 February 1939), reigned as Pope from 6 February 1922 to his death in 1939. He was the first sovereign of Vatican City from its creation as an independent state on 11 February 1929. He took as his papal motto, "Pax Christi in Regno Christi," translated "The Peace of Christ in the Kingdom of Christ."

Pius XI issued numerous encyclicals, including Quadragesimo anno on the 40th anniversary of Pope Leo XIII's groundbreaking social encyclical Rerum novarum, highlighting the capitalistic greed of international finance, and social justice issues, and Quas primas, establishing the feast of Christ the King. The encyclical Studiorum ducem, promulgated 29 June 1923, was written on the occasion of the 6th centenary of the canonization of Thomas Aquinas, whose thought is acclaimed as central to Catholic philosophy and theology. The encyclical also singles out the Pontifical University of Saint Thomas Aquinas, Angelicum as the preeminent institution for the teaching of Aquinas: "ante omnia Pontificium Collegium Angelicum, ubi Thomam tamquam domi suae habitare dixeris" (before all others the Pontifical Angelicum College, where Thomas can be said to dwell).
