The great Benedictine abbey just outside the walls of Trier is an imperial abbey that the archbishops of Trier have long tried to make their own.
Archbishop Albero's attempt in the 1130s failed, and in 1140 the pope confirmed the abbey's exemption. It holds estates and villages in the Trier country, the Luxembourg country and Rhenish Hesse; the counts of Luxembourg were its advocates from the 10th to the mid-12th century.
Who holds it
- Name
- Conrad
- Title
- Abbot of St Maximin
- Since
- attested 1177
- Confidence
- medium
Abbot Conrad is attested in 1177 and 1200; his successor Bartholomäus is attested in 1201 and 1207. Conrad is therefore the likely abbot on 1 January 1200, though the date of the change is not pinned.
What it holds
- The abbey and its immunity outside the north wall of Trier
- Estates and villages such as Kenn near Trier, Weimerskirch (given 723) and Mamer (960) in the Luxembourg country, Münsterappel and Guntersblum in Rhenish Hesse (893, 897), Norheim (962), and Uhler (first named in a charter of 1200)
How it was acquired
Merovingian and Carolingian royal gifts (723, 893, 897), Ottonian gifts (960, 962).
How things stand that morning
Conrad holds an independent abbey on Trier's doorstep, with the archbishop watching.
Wealth
Rents and wine from scattered estates; the abbey's relics and church at Trier.
Threats
- Trier's claim to the abbey
- Luxembourg's advocacy
Advocates and rivals
The archbishop of Trier, who wants to subject the abbey; the counts of Luxembourg, its old advocates.
Places of note
- Kenn: Abbey estate near Trier (893)
- Mamer: Abbey estate (960)
- Guntersblum: Abbey estate in Rhenish Hesse (897)
Where the sources disagree
