Background
Dedo married, before 985, Thietburga, the daughter of the Margrave Dietrich of Haldensleben, Lord of the Nordmark.
Dedo married, before 985, Thietburga, the daughter of the Margrave Dietrich of Haldensleben, Lord of the Nordmark.
As a young man, Dedo spent his childhood with his relative, the Margrave Rikdag, Lord of the Marches of Meissen, Zeitz and Merseburg, and was thus closely related to one of the most influential men of East Saxony. In 976 Dedo commanded a Bohemian army, conquered the March of Zeitz and robbed the Bishop’s Church. Dedo apparently had a good relationship with Archibishop Giselher of Magdeburg, who helped him gain comital rights in the northern Hassegau.
The years before Dedo’s death were overshadowed by a feud with the Counts of Walbeck.
When his father-in-law was deposed as the Margrave of the Nordmark, Dedo claimed the office of Margrave for himself. The office was granted instead to Lothair, Count of Derlingau and Nordthüringgau.
Lothair ruled the Nordmark from 983 to 1003. Dedo’s dispute with the House of Walbeck continued with Lothair"s son and successor Werner von Walbeck (1003-1009.
† 1014). Dedo was killed by Werner on November 13, 1009 along with his vassals near Mose at the confluence of the Tange and Elbe rivers.
Dedo I Count of Wettin and Thietburga of Haldenslebe had the following children:
v Theodoric II Count of Wettin, and from 1031 Margrave of Lausitz (* around 990, † 1034).
