Counts · Philip of Swabia: Staufen and royal lands · as at first light, 1 January 1200

Dillingen

The counts of Dillingen hold the Danube crossing at Dillingen, their old seat Wittislingen, the advocacy and burial church of Neresheim (founded by Hartmann I in 1095), and the king's advocacy over Ulm.

Adalbert III went on the Third Crusade with his brother in 1189-1190 and sided with Philip after Henry VI's death. His wife makes him Duke Louis's brother-in-law.

Who he is

Name
Adalbert III
Title
Count of Dillingen
Since
1180, when his father Hartmann III died and his brother Ulrich took the Kyburg lands (swi's record)
Born
Not pinned (died 1214)
Family
Married a daughter of Duke Otto I of Bavaria, probably named Heilika: the sister of Duke Louis I and cousin of the count palatine Otto VIII. One son and four daughters are attested; the son, Hartmann IV, is born in 1204 according to de.wikipedia, so on 1 January 1200 Adalbert has no son yet. A daughter married Count Ludwig of Württemberg; Sophia became prioress of Maria Medingen. The house's bishop is still two generations away: Hartmann (V), bishop of Augsburg 1248-1286, the last of the line.
Confidence
high

de.wikipedia (Grafen von Dillingen); fmg.ac (Württemberg).

Overlord

The duke of Swabia and the king.

What it holds

  • Dillingen castle and the Danube crossing
  • Wittislingen, the old seat
  • The advocacy of Neresheim abbey, the family burial place
  • The advocacy (Reichsvogtei) of Ulm (held by the counts; attested for Hartmann IV, not pinned for Adalbert III in 1200)
  • Lands south of the Danube

How it was acquired

Inheritance; the Kyburg lands split off in 1180.

Allies and rivals

Kin of the Kyburg (swi), the Wittelsbach, and later Württemberg; neighbours of the Staufen at Lauingen and Giengen and of the bishop of Augsburg.

How things stand that morning

Holds his county on 1 January 1200 and backs Philip (de.wikipedia: after Henry VI's death he sided with Philip; firm, medium-high confidence).

Wealth

The Danube crossing and markets; the Ulm advocacy (later the counts probably minted at Ulm).

Military

Dillingen castle; vassals and ministeriales. No figures.

Threats

  • No male heir yet

Places of note

  • Neresheim abbey: Family foundation (1095) and burial place.

Where the sources disagree

  • The assignment speaks of 'their kinsman the future bishop': no Dillingen bishop is in prospect on 1 January 1200; the house's bishop is Hartmann, bishop of Augsburg from 1248.

Evidence: Family and allegiance from de.wikipedia; no 1199-1200 charter seen.

On the map: Core only; the Ulm advocacy is drawn with the king's lands.
