The Lateran Treaty (Italian: Patti Lateranensi; Latin: Pacta Lateranensia) was one component agreement that made up the Lateran Pacts of 1929, the agreements made in 1929 between the Kingdom of Italy and the Holy See settling the "Roman Question". The treaty and associated pacts are named after the Lateran Palace, where they were signed on 11 February 1929. The Italian parliament ratified them on 7 June 1929. The Lateran Treaty recognized Vatican City as an independent state under the sovereignty of the Holy See. The Italian government, at the time led by Benito Mussolini as prime minister, also agreed to give the Roman Catholic Church financial compensation for the loss of the Papal States.[1] In 1947, the Lateran Treaty was recognized in the Constitution of Italy[2] as regulating the relations between the state and the Catholic Church.


The Lateran Pacts are often presented as three treaties: a 27-article treaty of conciliation, a three-article financial convention, and a 45-article concordat.[3][4][5][6][7][8] However, the website of the Holy See presents the pacts as two, making the financial convention an annex of the treaty of conciliation. In this presentation, the pacts consisted of two documents, the first of which had four annexes:[9]

  • A political treaty recognising the full sovereignty of the Holy See in the State of Vatican City, which was thereby established, a document accompanied by the annexes:
    • A plan of the territory of the Vatican City-State, with an area of 108.7 acres (44.0 ha)[10]
    • A list and plans of the buildings with extraterritorial privilege and exemption from expropriation and taxes
    • A financial convention agreed on as a definitive settlement of the claims of the Holy See following the loss in 1870 of its territories and property. (The Italian state agreed to pay 750 million lire immediately plus consolidated bearer bonds with a coupon rate of 5% and a nominal value of 1,000 million lire. It thus paid less than it would have paid, 3.25 million lire per annum, under the 1871 Law of Guarantees, which the Holy See had not accepted.)[11][12][13][14][15][16]
  • A concordat regulating relations between the Catholic Church and the Italian state
