Under the terms of the Law of Guarantees of 1871, the Italian government offered to Pius IX and his successors the use of, but not sovereignty over, the Vatican and Lateran Palaces and a yearly income of 3,250,000 Lire. The Holy See refused this settlement, on the grounds that the pope's spiritual jurisdiction required clear independence from any political power, and thereafter each pope considered himself a "prisoner in the Vatican". The Lateran Treaty ended this impasse.
