  Popes have always highlighted the inner link between the Virgin Mary as Mother of God and the full acceptance of Jesus Christ as Son of God. Since the 19th century, they were highly important for the development of mariology to explain the veneration of Mary through their decisions not only in the area of Marian beliefs (Mariology) but also Marian practices and devotions. Before the 19th century, Popes promulgated Marian veneration by authorizing new Marian feast days, prayers, initiatives, the acceptance and support of Marian congregations. Since the 19th century, Popes begin to use encyclicals more frequently. Thus Leo XIII, the Rosary Pope issued eleven Marian encyclicals. Recent Popes promulgated the veneration of the Blessed Virgin with two dogmas, Pius IX the Immaculate Conception in 1854 and the Assumption of Mary in 1950 by Pope Pius XII. Pius XII also promulgated the new feast Queenship of Mary celebrating Mary as Queen of Heaven and he introduced the first ever Marian year in 1954, a second one was proclaimed by John Paul II. Pius IX, Pius XI and Pius XII facilitated the veneration of Marian apparitions such as in Lourdes and Fátima. Later Popes such from John XXIII to Benedict XVI promoted the visit to Marian shrines (Benedict XVI in 2007 and 2008). The Second Vatican Council highlighted the importance of Marian veneration in Lumen gentium. During the council, Paul VI proclaimed Mary to be the Mother of the Church.
