Thietmar (margrave of the Walk of the East saxonne)

Thietmar († January 10th 1030) was the Count of Schwabengau and Nordthüringgau starting from 1010, and the Margrave of the Marche of the East saxonne of 1015 until its death. He was the son and the successor of Gero II. His/her mother was called Adelaide.

In 1028, Mieszko II of Poland launched an attack against the Walk of the East saxonne. The emperor Conrad II and his army quickly left the Duché of Saxony and went on a long and painful journey to come to besiege the Polish with Bautzen. During this time, Bretislav, the son of the duke Ulrich of Bohemia, assisted from the emperor while invading and by conquering the Marche from Moravie which had been lost by the Bohemia in 1003. In spite of this help, the head office of Bautzen failed (1029) and Conrad is turned over in the Rhineland to spend the winter, leaving the defense of the area between the hands of Thietmar and Thierry II of Brehna and Eilenberg. Thietmar is deceased at the beginning of the year 1030. Benefitting from its death, Mieszko plundered the area between the Saale and the Elba, attacker and setting fire to hundreds of villages.

Thietmar was buried with Helmershausen. His/her son Odo II succeeded to him. His/her Oda daughter married with Guillaume III of Weimar, then with Dedo II of Wettin.
