Please answer the following question: Information:  - Summi Pontificatus is an encyclical of Pope Pius XII published on 20 October 1939. The encyclical is subtitled "On the Unity of Human Society." It was the first encyclical of Pius XII and was seen as setting "a tone" for his papacy. It critiques major errors at the time, such as ideologies of racism, cultural superiority and the totalitarian state. It also sets the theological framework for future encyclical letters, such as "Mystici corporis Christi" (1943). The encyclical laments the destruction of Poland, denounces the Molotov-Ribbentrop Pact, and calls for a restoration of independent Poland.  - The pope (from "pappas", a child's word for "father") is the Bishop of Rome and, therefore, 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.  - Pope Saint Pius X, born Giuseppe Melchiorre Sarto, (2 June 1835  20 August 1914) was Pope from August 1903 to his death in 1914. He was canonized in 1954. Pius X is known for vigorously opposing modernist interpretations of Catholic doctrine, promoting traditional devotional practices and orthodox theology. His most important reform was to order the codification of the first Code of Canon Law, which collected the laws of the Church into one volume for the first time. He was also considered a pastoral pope, in the sense of encouraging personal holiness, piety and a daily lifestyle reflecting deep Christian values. He was born in the town of Riese, which would later append "Pio X" (Pius X's name in Italian) to the town's name.  - The Reichskonkordat ("Concordat between the Holy See and the German Reich") is a treaty negotiated between the Vatican and the emergent Nazi Germany. It was signed on 20 July 1933 by Cardinal Secretary of State (and later Pope Pius XII) Eugenio Pacelli on behalf of Pope Pius XI and Vice Chancellor Franz von Papen on behalf of President Paul von Hindenburg and the German government. It was ratified September 10, 1933 and it has been in force from that date right up until the current day. The treaty guarantees the rights of the Roman Catholic Church in Germany. When bishops take office Article 16 states they're required to take an oath of loyalty to the Governor or President of the German Reich established according to the constitution. The treaty also requires all clergy to abstain from working in and for political parties. Nazi breaches of the agreement began almost as soon as it had been signed and intensified afterwards leading to protest from the Church including in the 1937 "Mit brennender Sorge" encyclical of Pope Pius XI. The Nazis planned to eliminate the Church's influence by restricting its organizations to purely religious activities.  - Nazi Germany is the common English name for the period in German history from 1933 to 1945, when Germany was governed by a dictatorship under the control of Adolf Hitler and the Nazi Party (NSDAP). Under Hitler's rule, Germany was transformed into a fascist state in which the Nazi Party took totalitarian control over nearly all aspects of life. The official name of the state was "Deutsches Reich" from 1933 to 1943 and "Großdeutsches Reich" ("Greater German Reich") from 1943 to 1945. The period is also known under the names the Third Reich and the National Socialist Period (abbreviated as "NS-Zeit"). The Nazi regime came to an end after the Allied Powers defeated Germany in May 1945, ending World War II in Europe.  - Pope Pius XI, born Ambrogio Damiano Achille Ratti (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."  - Pope Pius XII, born Eugenio Maria Giuseppe Giovanni Pacelli (2 March 18769 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 (19171929), 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.  - The Secretary of State of His Holiness The Pope, commonly known as the Cardinal Secretary of State, presides over the Holy See Secretariat of State, which is the oldest and most important dicastery of the Roman Curia. The Secretariat of State performs all the political and diplomatic functions of the Holy See and the Vatican City.  - Luigi Maglione ( 2 March 1877 -- 23 August 1944 ) was an Italian Cardinal of the Roman Catholic Church . He was elevated to the cardinalate in 1935 and served as the Vatican Secretary of State under Pope Pius XII from 1939 until his death . Pius XII never replaced Maglione , opting to assume the responsibilities of the office himself , with the assistance of two undersecretaries .  - Adolf Hitler (20 April 1889  30 April 1945) was a German politician who was the leader of the Nazi Party ("Nationalsozialistische Deutsche Arbeiterpartei"; NSDAP), Chancellor of Germany from 1933 to 1945, and Führer ("Leader") of Nazi Germany from 1934 to 1945. As dictator of the German Reich, he initiated World War II in Europe with the invasion of Poland in September 1939 and was central to the Holocaust.
