    Notes 
    • Dedo of Wettin was born ca 950 (estimate) to Count Dietrich I and his wife.[1]

      The young Dedo spent his childhood with his relative, Margrave Rikdag, lord of the Margraves of Meissen, Zeitz and Merseburg, and was thus closely related to one of the most influential men in eastern Saxony.

      Marriage Dedo was married since ca 980 to Thietburga, the daughter of Margrave Dietrich von Haldensleben, lord of the Nordmark. The date is not sure but had to be some time before the death of Dietrich's death in 985.[2]

      In the years from 974 to 985, Dedo I was involved in the rebellion of the Bavarian Duke Henry of Bavaria against Emperor Otto II and later also against his son Otto III, to whom the Bavarian duke only finally submitted in Frankfurt in June 985. In 976, Dedo commanded a Bohemian army that captured Zeitz and robbed the bishop's church. It is said that he also took his own mother away as a prisoner with the spoils.

      Dedo obviously had a good relationship with Archbishop Giselher of Magdeburg. After the death of Count Binizo, he procured him the rights of count in northern Hassegau. Dedo also successfully claimed the Burgward of Zörbig for himself and his brother Friedrich.

      The years before Dedo's death were overshadowed by a feud with the Walbeckers, the cause of which is unknown. As the husband of the daughter of the Margrave of Nordmark, Dedo claimed the office for himself after his death, but Walbeck's Lothar received it. Lothar ruled the Nordmark from 993 to 1003. Bishop Thietmar of Merseburg, a nephew of Lothar, recounts in his chronicle that Dedo I took part in the devastation of Wolmirstedt Castle, which was owned by Walbeck. The Wettin was also at odds with Margrave Lothar's son and successor Werner von Walbeck (1003-1009; 1014). Dedo was killed on 13 November 1009 together with his vassal Egilhard by his adversary Werner near Mose not far from Wolmirstedt.
