Essen

The house of noble canonesses at Essen, rich in Ottonian treasure and royal abbesses, is the lady of the town that grew around it and of wide estates between the Ruhr and the Lippe.

Its abbess will first be called a princess of the Empire in 1228. The real power on the ground is its advocate: the advocacy belongs to the Isenberg branch of the counts of Altena, and the quarrel over it will lead in 1225 to the murder of Archbishop Engelbert of Cologne.

Who holds it

Name
Elisabeth I
Title
Abbess of Essen
Since
1172
Confidence
high

Abbess from 1172 until before 1216, at the same time abbess of St Maria im Kapitol in Cologne and of Vreden. Her successor Adelheid follows in 1216. Her family and her stance in the throne war are not pinned in the sources consulted.

What it holds

  • Essen: the abbey and the market town around it
  • Estates and manors between the Ruhr and the Lippe (and, by older grants, on the Rhine; their state in 1200 not pinned)

How it was acquired

Founded in the 9th century; enriched by the Ottonian abbesses (Mathilde, Sophia, Theophanu). The abbess is first styled princess in 1228.

How things stand that morning

Elisabeth rules a rich house whose estates are under pressure from its own advocates.

Wealth

Manorial rents from the Ruhr and Hellweg country; the Essen market; the treasury of Ottonian gold.

Threats

  • The Isenberg advocates
  • Loss of estates to ministerials and vassals

Advocates and rivals

The counts of Isenberg (of the Altena house, Archbishop Adolf's kin), advocates of Essen, who use the advocacy to squeeze the abbey's estates; the abbey of Werden next door; the archbishop of Cologne.

Where the sources disagree

Evidence: The abbess and the later princely style are attested; the advocacy by the Isenberg counts is well known from the events of 1225; the abbey's lordship in 1200 is not otherwise defined in the sources consulted.

On the map: Only the abbey town is drawn; the estates are scattered.
