In 1950 the Academy gained international recognition with the organisation of the first
International Mariological Congress and the eighth
International Marian Congress. Congresses in 1948 and 1958 followed. The 23rd International Congress was held on September 4–9, 2012, and emphasized developments and new perspectives in contemporary Roman Catholic mariology (since Vatican Council II, after which it declined, and then was revived starting with the pontificate of
Pope Paul VI). The work of PAMI has a twofold purpose: to promote and favor the scientific studies of the Virgin Mary, be they speculative or historical-critical, and to organize periodic Marian Conventions and Conferences. The results of which are edited and published in mariological collections, both historical and theological. It is the will of the Papacy that it be an International, yet centralized body for the coordination of Mariological work in various nations and in the single scientific entities. This task of coordination was highlighted by the pontifical document of Pope John XXIII: “It is our desire that this our Academy continue, as it has up till now, to work for the friendly union of forces and intent of all other Marian Academies and Societies existing in the world so as to contribute to the praise and honor of the Virgin Mary.” The PAMI also coordinates the teachers of mariology for which it organizes periodic meetings. == Marian societies and academies ==
