HEINRICH, son of OTTO "dem Erlauchten" Graf [im Südthüringau] & his wife Hedwig [Babenberg] ([876]-Memleben[135] 2 Jul 936, bur Quedlinburg Stiftskirche). Thietmar records that Heinrich was "born of the noble lineage of Otto and Hadwig"[136]. According to the Annalista Saxo, he was son of the unnamed sister of Adalbert [Babenberg], with whom he and his brothers fought against the Konradiner family, his complete parentage being recorded in a later passage[137]. He was elected HEINRICH I "der Vogelsteller/the Fowler" King of Germany at Fritzlar 6 May 919, but refused unction offered by Heriger Archbishop of Mainz[138]. King Heinrich re-established Saxon domination over the Slavs after successful campaigns against the Hevelli in 928 and against the Daleminzi and Bohemians in 929[139]. He founded Meissen in [928/29][140]. He defeated "Knud I" King of Denmark[141]. He defeated the Magyars at the battle of Riade near Merseburg in 933, their first major setback in their raids on western Europe[142]. The necrology of Fulda records the death "936 Kal Iul" of "Heinrih rex"[143].

Thietmar names Hatheburg as daughter of "lord Erwin", specifying that she was widowed (without naming her first husband), when recording her marriage to Heinrich[146]. Widukind records the mother of "Thancmari" as "filia materteræ Sigifridi"[147]. She had become a nun after the death of her first husband, which presumably provided the reason for "the outrage perpetrated through this marriage" and the basis for the couple's separation although it is not explicitly expressed as such by Thietmar[148].

Thietmar names Mathilde as daughter of "Dietrich and Reinhild" when recording her marriage to Heinrich, specifying the was "a descendant of the lineage of King Widukind"[150].

She established the convent there thirty days after the death of her husband[153]. She played an active part in encouraging the rebellion of her son Heinrich in 939 and was included in the reconciliation of 941[154]. Lay Abbess of Nivelles.
