Lateran Treaty
The Lateran Treaty (; ) was one of the Lateran Pacts of 1929 or Lateran Accords, agreements made in 1929 between the Kingdom of Italy and the Holy See, settling the "Roman Question". They are named after the Lateran Palace, where they were signed on 11 February 1929. The Italian parliament ratified them on 7 June 1929. It recognized Vatican City as an independent state, with the Italian government, at the time led by Benito Mussolini as prime minister, agreeing to give the Roman Catholic Church financial compensation for the loss of the Papal States. In 1947, the Lateran Treaty was recognized in the Constitution of Italy as regulating the relations between the state and the Catholic Church.
Legal status of the Holy See
For a further group, the legal personality of the Holy See in international law arises from the Lateran Treaty, which, in their view, conferred international standing to the central government of the Catholic Church. In this sense, Oppenheim argued that "the previously controversial international position of the Holy See was clarified as the result of the Treaty of 11 February 1929, between the Holy See and Italy - the so called Lateran Treaty. (...) The Lateran Treaty marks the resumption of the formal membership, interrupted in 1871, of the Holy See in the society of states."
