Lateran Treaty
Negotiations for the settlement of the Roman Question began in 1926 between the government of Italy and the Holy See, and culminated in the agreements of the Lateran Pacts, signed—the Treaty says—for King Victor Emmanuel III of Italy by Benito Mussolini, Prime Minister and Head of Government, and for Pope Pius XI by Pietro Gasparri, Cardinal Secretary of State, on 11 February 1929. It was ratified on 7 June 1929. The agreements were signed in the Lateran Palace, hence the name by which they are known.
Pontifical Oriental Institute
The Institute has been located across from the Basilica of Santa Maria Maggiore since 1926. It is separated from the Collegium Russicum by the Church of Saint Antony. According to article 16 of the Lateran Treaty, signed in 1929 between Italy and the Holy See, the property of the Oriental Institute enjoys a certain level of extraterritoriality, with the Holy See having all rights over the infrastructure without interference from the Italian State, and free from all Italian taxation.
