Pope Pius XII in the context of "Pope Paul VI"

Queen of Heaven (Latin: Regina Caeli) is a title given by the Catholic Church and Eastern Orthodoxy, to Mary, mother of Jesus, and, to a lesser extent, in Evangelical Lutheranism and Anglicanism. The title has long been a tradition, included in prayers and devotional literature and seen in Western art in the subject of the Coronation of the Virgin from the High Middle Ages, long before the Church gave it a formal definition status.

The Catholic teaching on this subject is expressed in the papal encyclical Ad Caeli Reginam, issued by Pope Pius XII in 1954. Therein, the pope states that Mary is called Queen of Heaven because her son, Jesus Christ, was charged as being "King of Israel" and the heavenly king of the universe. This would render the mother of the king as the "queen mother" of Israel.

Deiparae Virginis Mariae (Latin for "Virgin Mary Mother of God"), is an encyclical of Pope Pius XII released on May 1, 1946 addressed to all Catholic bishops on the possibility of defining the Assumption of the Blessed Virgin Mary as a dogma of faith.

The encyclical states that for a long time numerous petitions have been received from cardinals, patriarchs, archbishops, bishops, priests, religious of both sexes, associations, universities and innumerable private persons, all begging that the bodily Assumption into heaven of the Blessed Virgin should be defined and proclaimed as a dogma of faith. This was also fervently requested by almost two hundred fathers in the Vatican Council (1869–1870).

Rome, along with Vatican City, was bombed several times during 1943 and 1944, primarily by Allied and to a smaller degree by Axis aircraft, before the city was liberated by the Allies on June 4, 1944. Pope Pius XII was initially unsuccessful in attempting to have Rome declared an open city, through negotiations with U.S. President Franklin D. Roosevelt via Archbishop (later Cardinal) Francis Spellman. Rome was eventually declared an open city on August 14, 1943 (a day after the last Allied bombing raid) by the defending Italian forces.

The first bombing raid was on July 19, 1943, when 690 aircraft of the United States Army Air Forces (USAAF) flew over Rome and dropped 9,125 bombs on the city. Though the raid targeted the freight yard and steel factory in the San Lorenzo district of Rome, Allied bombs also struck the district's apartment blocks, damaging the Papal Basilica and killing 1,500 people. Pius XII, who had previously requested Roosevelt not to bomb Rome due to "its value to the whole of humanity", paid a visit to the affected regions of the district; photographs of his visit later became a symbol of anti-war sentiments in Italy. The Allied bombing raids continued throughout 1943 and extended into 1944. In the United States, while the majority of the American media supported the bombing raids, many Catholic newspapers condemned them.

Charles-Marie-Photius Maurras (/mɔːˈrɑːs/; French: [ʃaʁl moʁas]; 20 April 1868 – 16 November 1952) was a French author, politician, poet and critic. He was an organiser and principal philosopher of Action Française, a political movement that was monarchist, medievalist, conservative, corporatist, integralist, nationalist, traditionalist, and counter-revolutionary. Maurras also held anti-capitalist, anti-communist, anti-liberal, anti-Masonic, anti-Nazi, anti-Protestant and antisemitic views. His ideas greatly influenced National Catholicism and integral nationalism, and led to the political doctrine of Maurrassisme.

Raised Roman Catholic, Maurras went deaf and became an agnostic in his youth, but remained anti-secularist and politically supportive of the Catholic Church. An Orléanist, he began his career by writing literary criticism and became politically active as a leading anti-Dreyfusard. In 1926 Pope Pius XI issued a controversial papal condemnation of Action Française, which was swiftly repealed by Pope Pius XII in 1939. Maurras was elected to the Académie Française in 1938, and later expelled in 1945.

Our Lady of Fátima (Portuguese: Nossa Senhora de Fátima, pronounced [ˈnɔsɐ sɨˈɲɔɾɐ ðɨ ˈfatimɐ]; formally known as Our Lady of the Holy Rosary of Fátima) is a Catholic title of Mary, mother of Jesus, based on the Marian apparitions reported in 1917 by three shepherd children at the Cova da Iria in Fátima, Portugal. The three children were Lúcia dos Santos and her cousins Francisco and Jacinta Marto. José Alves Correia da Silva, Bishop of Leiria, declared the events worthy of belief on 13 October 1930.

Pope Pius XII granted a pontifical decree of canonical coronation via the papal bull Celeberrima solemnia towards the venerated image on 25 April 1946. The designated papal legate, Cardinal Benedetto Aloisi Masella, carried out the coronation on 13 May 1946, now permanently enshrined at the Chapel of the Apparitions of Fátima. The same Roman Pontiff also raised the Sanctuary of Fátima to the status of a minor basilica by the apostolic letter Luce superna on 11 November 1954.

Ad Caeli Reginam is an encyclical of Pope Pius XII, given at Rome, from St. Peter's Basilica, on the feast of the Maternity of the Blessed Virgin Mary, the eleventh day of October, 1954, towards the end of the Marian year, in the sixteenth year of his Pontificate. The encyclical is an important element of the Mariology of Pope Pius XII. It established the feast Queenship of Mary.

Munificentissimus Deus (Latin: The most bountiful God) is an apostolic constitution published in 1950 by Pope Pius XII. It defines ex cathedra the dogma of the Assumption of the Blessed Virgin Mary. It was the first and thus far the only ex-cathedra infallible statement since the official ruling on papal infallibility was made at the First Vatican Council (1869–1870). In 1854 Pope Pius IX had made an infallible statement with Ineffabilis Deus on the Immaculate Conception of the Virgin Mary, which was a basis for this dogma.

Pope John XXIII (born Angelo Giuseppe Roncalli; 25 November 1881 – 3 June 1963) was head of the Catholic Church and sovereign of the Vatican City from 28 October 1958 until his death on 3 June 1963. He is the most recent pope to take the pontifical name "John".

Roncalli was among 13 children born to Marianna Mazzola and Giovanni Battista Roncalli in a family of sharecroppers who lived in Sotto il Monte, a village in the province of Bergamo, Lombardy. He was ordained to the priesthood on 10 August 1904 and served in a number of posts, as nuncio in France and a delegate to Bulgaria, Greece and Turkey. In a consistory on 12 January 1953 Pope Pius XII made Roncalli a cardinal as the Cardinal-priest of Santa Prisca in addition to naming him as the Patriarch of Venice. Roncalli was unexpectedly elected pope on 28 October 1958 at age 76 after Pope Pius XII's death. Pope John XXIII surprised those who expected him to be a caretaker pope by calling the historic Second Vatican Council (1962–1965), the first session opening on 11 October 1962, which is now his feast.
