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 the Kingdom of Italy during the period from the capture of Rome by the Royal Italian Army on 20 September 1870 until the Lateran Treaty of 11 February 1929. Part of the process of the unification of Italy, 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 country.
