Pope Pius XII , born Eugenio Maria Giuseppe Giovanni Pacelli (; 2 March 1876 – 9 October 1958), reigned 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.
