Dietrich II of Wettin and Matilda, daughter of
Eckard I of Meissen.
Life
Dedi inherited the Ostmark from its last dynast, the childless
Odo II, because he had married his sister, Oda (died before 1068). Oda was herself the widow of

and
Otto, margraves of Meissen successively. When Otto his stepson died, Dedi married his widow,
Adela of Louvain, and in her name claimed the
Meissen March.
Otto died in 1067 and was succeeded by
Egbert I, but Dedi married his widow in 1069 and rebelled. In claiming the Meissen March through his wife, Dedi was challenging the royal prerogative in the marches. With him in his revolt was
Albert II of Ballenstedt, who raided the monastery of
Nienburg, a foundation of the family of Dedi's first wife. Adela of Louvain for her part aggressively supported her husband, so much so that
Lambert of Hersfeld was compelled to call her a (rough meaning "raging wife").
Adalbert of Bremen, one of the regents of the young king
Henry IV, frustrated the Thuringian rebels and preserved the peace in Thuringia and Meissen. Dedi was confined to Lusatia, where he was succeeded by his eldest son,
Dedi II.
