Giulio Andreotti (Rome, 1919-2013) was one of the most important figures in Italian politics after the Second World War. This collection, drawn from Andreotti's papers held by the Istituto Luigi Sturzo, features letters, telegrams, reports, notes, and memoranda written by officials from the Italian Ministry of Foreign Affairs (MAE) and the Ministry of Defense and various Italian Ambassadors and diplomatic advisers. The materials are broadly related to NATO affairs and include dossiers prepared by MAE officials for the sessions of North Atlantic Council, special meetings of NATO Ministers of Foreign Affairs or Ministers of Defense, Andreotti’s visits abroad, and visits of important international leaders in Italy. The materials were selected and described by Dr. Lodovica Clavarino as part of a joint Wilson Center-Roma Tre University-Istituto Sturzo project. For further information, see the introduction by Leopoldo Nuti and Lodovica Clavarino, "The Giulio Andreotti Archive: A First-Hand Account of NATO."
