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.
