The Diocese of Hildesheim (Latin:Dioecesis Hildesiensis) is a diocese or ecclesiastical territory of the Latin Rite of the Catholic Church in Germany. Founded in 815 as a missionary diocese by King Louis the Pious, his son Louis the German appointed the famous former archbishop of Rheims, Ebbo, as bishop. Between 1235 and 1802, the bishop of Hildesheim was also Prince of the Holy Roman Empire. His territory was the Bishopric of Hildesheim.
The Diocese of Hildesheim continues to exist; today, it covers those parts of the State of Lower Saxony that are east of the River Weser, northern neighbourhoods in Bremen, and the city of Bremerhaven. The current bishop is Norbert Trelle who was appointed in 2006. The diocese is a suffragan to the Archdiocese of Hamburg since 1994. Originally Hildesheim was suffragan to Mainz until 1805. Then it was an exempt diocese until 1930, before it was part of the Middle German Ecclesiastical Province with Paderborn Archdiocese as metropolitan between 1930 and 1994.
Until 1824 the diocesan ambit remained unchanged, despite various changes of the political borders in history up to this date. After the Napoleonic wars the newly established Kingdom of Hanover stipulated with the Holy See to extend the Hildesheim diocesan ambit to all of the then Hanoverian territory east of the Weser river. The newly included areas were Lutheran with a little Catholic diaspora and had formed part of the defunct dioceses of Bremen, of Mainz and of Verden before the Reformation.
Hannover's cession of land for Bremerhaven in 1827 to the prevailingly Reformed Bremen State did not alter the diocesan ambit. In 1834 the prevailingly Lutheran Duchy of Brunswick left the Apostolic Vicariate of Anhalt and agreed to extend Hildesheim's ambit to the ducal territory. Thus the diocese covered areas in three sovereign states, with all of which and thus all the diocesan area becoming part of united Germany in 1871.
The incorporation of Hanoverian suburbs into Bremen city (Bremen North borough) in 1939 did not alter the ambit. In 1965 Hildesheim ceded that part of the then Hoya County District east of the Weser to the diocese of Osnabrück, whereas Osnabrück in return ceded Cuxhaven, Neuwerk, Scharhörn, Schaumburg-Lippe, as well as parts of the districts of Verden, Holzminden, Hameln-Pyrmont located west of the Weser, and the quarters of Nienburg upon Weser west of the river to Hildesheim. In 1995 Hildesheim ceded its Harburg deanery in Hamburg south of the Elbe to the Archdiocese of Hamburg following the erection of this new see.
