The agreements included a political treaty which created the state of the Vatican City and guaranteed full and independent sovereignty to the Holy See. The Pope was pledged to perpetual neutrality in international relations and to abstention from mediation in a controversy unless specifically requested by all parties. In the first article of the treaty, Italy reaffirmed the principle established in the 1848 Constitution of the Kingdom of Italy, that "the Catholic, Apostolic and Roman Religion is the only religion of the State". The attached financial agreement was accepted as settlement of all the claims of the Holy See against Italy arising from the loss of temporal power of the Papal States in 1870.
