The Diocese of Terlizzi (Latin: Dioecesis Terlitiensis) was a Roman Catholic diocese located in the town of Terlizzi the region of Apulia in southern Italy, in the province of Bari, lying to the west of the seaport of Bari on the Adriatic Sea.
The diocese of Giovinazzo, which included the town (oppidum) of Terlizzi, was erected in the 11th century.
Since the French occupation had seen the abolition of many Church institutions in the Kingdom, as well as the confiscation of most Church property and resources, it was imperative that Pope Pius VII and King Ferdinand IV reach agreement on restoration and restitution.
[4] The right of the king to nominate the candidate for a vacant bishopric was recognized, as in the Concordat of 1741, subject to papal confirmation (preconisation).
[5] On 27 June 1818, Pius VII issued the bull De Ulteriore, in which, among many other things, he dealt with dioceses which had been directly subject to the Holy See.
