when did vatican city become a sovereign state
Vatican City This situation was resolved on 11 February 1929, when the Lateran Treaty between the Holy See and the Kingdom of Italy was signed by Prime Minister and Head of Government Benito Mussolini on behalf of King Victor Emmanuel III and by Cardinal Secretary of State Pietro Gasparri for Pope Pius XI.[12][10][25] The treaty, which became effective on 7 June 1929, established the independent state of Vatican City and reaffirmed the special status of Catholicism in Italy.[26]
Second Vatican Council The Second Vatican Council, fully the Second Ecumenical Council of the Vatican[2] (Latin: Concilium Oecumenicum Vaticanum Secundum) and informally known as Vatican II, addressed relations between the Catholic Church and the modern world.[3] It was the twenty-first and most recent ecumenical council of the Catholic Church and the second to be held at St. Peter's Basilica in the Vatican. The council, through the Holy See, formally opened under the pontificate of Pope John XXIII on 11 October 1962 and closed under Pope Paul VI on the Feast of the Immaculate Conception on 8 December 1965.
