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.
Vatican lira
The Papal States, by then reduced to a smaller area close to Rome, used its own lira between 1866 and 1870, after which it ceased to exist. In 1929, the Lateran Treaty established the State of the Vatican City and, according with the terms of the Treaty, a distinct coinage was introduced, denominated in centesimi and lire, on par with the Italian lira. Italian coins and banknotes were legal tender in the Vatican City. The Vatican coins were minted in Rome and were also legal tender in Italy and San Marino.
