Foreign Minister

Martino was a prominent Liberal politician. He was elected in 1948 to the Chamber of Deputies, becoming briefly Minister of Public Education in 1954, under Christian Democrat Mario Scelba. In the late 1954, Martino became Minister of Foreign Affairs after the replacement of Attilio Piccioni, involved in the Montesi Affair.^[1] He maintained his Ministry also during the Antonio Segni's Cabinet (1954-1957), but was finally removed from office by new Prime Minister Adone Zoli.^[2]

As Minister of Foreign Affairs, Martino promoted a better European integration and internationalism, first with the Messina Conference in 1955. In 1956, he obtained the Italian acceptance to the United Nations. In the same year Martino, along with Halvard Lange from Norway and Lester Pearson from Canada, became a "sage" of the NATO, promoting its involvement in civil areas.^[3] Martino also attended the Treaty of Rome in 1957, establishing the European Economic Community.

Armoire's affair

In 1956, the newspaper La Repubblica published an article where Martino said that investigations on the German war crimes in Italy during World War II would have a negative impact on the Germany's integration in Europe, like an internal disapprove of the NATO. In 1994, with discovery in a military base of an armoire with secret documents on Nazi war crimes in Italy, nickname "Armoire of Shame" ("Armadio della Vergogna"), emerged that Martino blocked the investigations to avoid a German isolation during Cold War.^[4]
