Background
She was the youngest daughter of Eckard I, Margrave of Meissen by his wife Suanhilde, daughter of Hermann Billung, Margrave of Saxony.
She was the youngest daughter of Eckard I, Margrave of Meissen by his wife Suanhilde, daughter of Hermann Billung, Margrave of Saxony.
On 30 January 1018 the Peace of Bautzen was signed between Henry II, Holy Roman Emperor and Bolesław I the Brave. During the peace negotiations in the Ortenburg Castle, was decided that Bolesław I (then a widower) reinforced his dynastic bonds with the German nobility through a marriage. The wedding took place four days later after the formal signing of the peace treaty, on 3 February in the castle of Cziczani (also Sciciani, at the site of either modern Groß-Seitschen or Zinnitz or Zützen).
The marriage (which only produced one known child, a daughter named Matilda (b aft 1018 – d aft 1036) after Oda"s sister, by marriage Margravine of Lower Lusatia) probably wasn"t happy.
The main reasons of the failure of the union were the almost thirty years of difference between the spouses and the Bolesław I"s affair with Predslava, daughter of Grand Prince Vladimir I of Kiev. Another factor maybe was the apparently dissolute life of Oda before her wedding.
However, this is only a conjecture noted by medieval sources. Oda"s further fate and place of burial are unknown.
