 Administration of the Property of the Holy See

Administration of the Property of the Holy See (, abbreviated ABSS) was a commission that, until 1967, administered the property of the Holy See other than the money in cash and Italian government bonds received when the Financial Convention attached to the Lateran Treaty of 1929 was implemented.Its origin lay in the decision of Pope Leo XIII on 9 August 1878 to appoint his then Secretary of State also as Prefect of the Sacred Palace and Administrator of the patrimony remaining to the Holy See after the complete loss of the Papal States in 1870.
