Prisoner in the Vatican

A prisoner in the Vatican (Italian: Prigioniero nel Vaticano; Latin: Captivus Vaticani) or prisoner of the Vatican described the situation of the pope with respect to Italy during the period from the capture of Rome by the armed forces of the Kingdom of Italy on 20 September 1870 until the Lateran Treaty of 11 February 1929. Part of the process of Italian unification, the city's capture ended the millennium-old temporal rule of the popes over Central Italy and allowed Rome to be designated the capital of the new nation. Although the Italians did not occupy the territories of Vatican Hill delimited by the Leonine walls and offered the creation of a city-state in the area, the popes from Pius IX to Pius XI refused the proposal and described themselves as prisoners of the new Italian state.
