When was the Lateran Treaty?
Lateran Treaty
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[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 750,000,000 lire immediately plus consolidated bearer bonds with a coupon rate of 5% and a nominal value of 1,000,000,000 lire. It thus paid less than it would have paid {3.25 million liras annually} 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
