ラテラノ条約
In 1926, the king allowed Mussolini to do what he prevented Orlando from doing in 1919, giving permission to open negotiations with the Vatican to end the "Roman Question". In 1929, Mussolini, on behalf of the King, signed the Lateran Treaty. The treaty was one of the three agreements made that year between the Kingdom of Italy and the Holy See. On 7 June 1929, the Lateran Treaty was ratified and the "Roman Question" was settled.
