Dedo I, Count of Wettin (c. 950 – 13 November 1009), also known as Dedo I of 
Wettin, was a son of Theodoric I of Wettin and Jutta of Merseburg.[1]

As a young man, Dedo spent his childhood with his relative Rikdag, Margrave of 
Meissen, Zeitz and Merseburg, and was thus closely related to one of the most 
influential men of East Saxony. Dedo married, before 985, Thietburga, the daughter of 
Dietrich of Haldensleben, Margrave of the Nordmark.

In the years 974-985 Dedo I was involved in the rebellion of Duke Henry II of Bavaria 
against the Holy Roman Emperor Otto II and later against his son Otto III, until June 
985, when the Bavarian Duke was finally subjugated in Frankfurt.

In 976 Dedo commanded a Bohemian army, conquered the March of Zeitz and robbed 
the Bishop’s Church. It is alleged that he even took his own mother prisoner.

Dedo apparently had a good relationship with Archibishop Giselher of Magdeburg, who 
helped him gain comital rights in the northern Hassegau. Moreover, Dedo successfully 
claimed the Castle of Zörbig for himself and his brother Friedrich.

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.

Bishop Thietmar of Merseburg, Lothair’s nephew, tells in his chronicle that Dedo I was 
involved in the devastation of the castle of Wolmirstedt which was in the possession 
of the Counts of Walbeck. 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 and Thietburga of Haldensleben had the following children:
Theodoric II Count of Wettin, and from 1031 Margrave of Lausitz (around 990, † 1034).
