Diocese of Konstanz in the context of Diocese of Rottenburg-Stuttgart

Konstanz (/ˈkɒnstənts/ KON-stənts, US also /ˈkɔːnstɑːnts/ KAWN-stahnts, German: [ˈkɔnʃtants] or [ˈkɔnstants] , Alemannic German: [ˈkoʃd̥əts, ˈxoʃd̥əts]), traditionally known as Constance in English, is a university city with approximately 83,000 inhabitants located at the western end of Upper Lake Constance in the Baden-Württemberg state of south Germany. The city houses the University of Konstanz and was the residence of the Roman Catholic Diocese of Konstanz for more than 1,200 years.

The Prince-Bishopric of Constance (German: Hochstift Konstanz, Fürstbistum Konstanz, Bistum Konstanz) was a small ecclesiastical principality of the Holy Roman Empire from the mid-12th century until its secularisation in 1802–1803. In his dual capacity as prince and as bishop, the prince-bishop also administered the Diocese of Konstanz, which existed from about 585 until its dissolution in 1821, and whose territory extended over an area much larger than the principality. It belonged to the ecclesiastical province of Mainz since 780/782.
