The sum thereby given to the Holy See was actually less than Italy declared it would pay under the terms of the Law of Guarantees of 1871, by which the Italian government guaranteed to Pope 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 as indemnity for the loss of sovereignty and territory. The Holy See, on the grounds of the need for clearly manifested independence from any political power in its exercise of spiritual jurisdiction, had refused to accept the settlement offered in 1871, and the popes thereafter until the signing of the Lateran Treaty considered themselves prisoners in the Vatican, a small, limited area inside Rome.
