The archbishop of Trier is lord of the old imperial city of Trier and of scattered estates, forests and castles on the Moselle, in the Eifel and Hunsrück, and around Koblenz, the core of his lower lands since Henry II's gift of 1018, guarded by the great castle of Ehrenbreitstein.
In 1197 Johann I bought out the counts palatine's overriding advocacy, so he is freer in his own house than any of his predecessors; but he has pledged home manors to his own chapter, and the new count palatine is Otto IV's brother. Johann is Staufen, cautiously.
Who holds it
- Name
- Johann I
- Title
- Archbishop of Trier, arch-chancellor for Gaul and Arles
- Since
- 1189-1190
- Confidence
- high
Probably of the lesser nobility of the Speyer country; archdeacon of Speyer and provost of St German there from 1173; imperial chancellor 1186-1189, then elected to Trier at Henry VI's wish. He consecrated the rebuilt cathedral on 1 May 1196 and in 1197 freed his church from the overriding advocacy of the counts palatine. He backed Philip in 1198, well rewarded, but keeps a door open: in 1209 he will ride to Rome with Otto.
Dies 14 or 15 July 1212 and is buried at the Cistercian abbey of Himmerod.
What it holds
- Trier: lord of the city since about 902, with immunity and comital rights granted in 898-902 and confirmed in 947; the cathedral, consecrated anew in 1196, holds the Holy Robe
- The archbishop's manors of Pfalzel, Ehrang and Kordel by Trier, pledged in 1190 to the cathedral chapter to pay the costs of his election (redemption by 1200 not pinned)
- Koblenz with its royal estate, given by Henry II to Archbishop Poppo in 1018: the core of the lower archbishopric on the lower Moselle, the Rhine and the Lahn
- Ehrenbreitstein: bought by Poppo about 1020 and strengthened by Hillin about 1160; the see's strongest castle and its bridgehead on the right bank of the Rhine
- Royal forests in the Hunsrück (897) and the Eifel (973)
- Estates and rents in the Trier country, on the Saar, the middle Moselle, the Hochwald, in the Eifel, on the Maifeld, around Koblenz and in the Westerwald, as listed in the see's rent-book of about 1215 (holdings place by place in 1200 not pinned)
- Feudal overlordship, won by Johann, over the castles of Sayn, Altenburg and Starkenburg on the Moselle (dates not pinned)
- The Westerwald castle of Humbach (rebuilt by Archbishop Dietrich after its destruction and renamed Montabaur about 1217); its state in 1200 is not pinned
How it was acquired
City lordship and comital rights from Carolingian and Ottonian grants (897-973); Koblenz from Henry II (1018); Ehrenbreitstein bought about 1020. The palatine advocacy was bought out in 1197. The building of a castle territory begins in earnest only under Dietrich of Wied (1212-1242).
How things stand that morning
Johann holds Trier, Koblenz and Ehrenbreitstein firmly. He is Philip's man but has kept his options open; Koblenz and the lower Moselle lie close to the Welf palatine's castles. His church is free of the palatines' advocacy but in debt to its own chapter.
Wealth
Moselle wine; the Rhine and Moselle crossings and tolls at Koblenz; the Trier market and mint; the Hunsrück and Eifel forests; pilgrims to St Matthias (the apostle's tomb) and to the cathedral.
Threats
- The Welf count palatine Henry and his castle of Thurant
- The counts of Luxembourg over St Maximin and Echternach
- The citizens of Trier
- His chapter's hold on his pledged manors
Advocates and rivals
The counts palatine of the Rhine were the see's chief advocates until 1197; the palatinate is now held by Henry of Brunswick, Otto IV's brother, whose new castle of Thurant on the lower Moselle (built about 1198) sits in Trier's country. The counts of Luxembourg (advocates of St Maximin and Echternach), Sponheim, Sayn, Vianden and Virneburg; the citizens of Trier; and the great abbeys of St Maximin and Echternach, which refuse to be Trier's subjects.
Places of note
- Ehrenbreitstein: The see's strongest castle, opposite Koblenz
- Thurant: Castle of the Welf count palatine Henry, built about 1198 (not Trier's)
- Humbach (Montabaur): Trier castle in the Westerwald, rebuilt as Montabaur about 1217
- Himmerod Abbey: Cistercian abbey where Johann will be buried
Where the sources disagree
- The campaign notes call Johann 'Henry VI's former chancellor'. The NDB article makes him chancellor of Frederick I (1186-1189), elected to Trier at Henry VI's request. Source: https://www.deutsche-biographie.de/sfz37626.html
Evidence: The early grants, Koblenz, Ehrenbreitstein, the 1190 pledge and the 1197 buy-out are attested; the archbishop's estates place by place in 1200 are not, so only the city, the pledged manors and the Koblenz block are drawn.
On the map: Only the attested centres are drawn. The archbishop's many estates, rents, forests and fiefs along the Moselle and in the Eifel, Hunsrück and Westerwald are real but cannot be placed one by one for 1200; the map understates the see's presence.
