About Brun I, count of Brunswick

BRUNO, son of [EKBERT "der Einäugige Graf im Hastfalagau] & his wife --- ([975/85]-murdered near Niedorp[10] [1010/11][11]). There is no proof that Bruno von Braunschweig was the son of Ekbert "der Einäugige" but this appears probable in view of the names which are common to the two families and also the common references to the Derlingau. Bruno is shown in Europäische Stammtafeln as the brother of Wichmann [III] Graf im Duffelgau and Ekbert Graf im Derlingau, while another table shows Wichmann [III] as son of Ekbert[12]. His birth date range is estimated from his estimated marriage date. The estimated birth date ranges of both Wichmann [III] and Bruno are consistent with their having been brothers. Bruno founded Braunschweig. He was a candidate for the German throne in 1002[13] in opposition to Heinrich IV Duke of Bavaria, who was elected as Heinrich II King of Germany. m ([1003/05]%29 as her first husband, GISELA of Swabia, daughter of HERMANN II Duke of Swabia & his wife Gerberga of Upper Burgundy (11 Nov 990-Goslar 16 Feb 1043, bur Speyer Cathedral). The Annalista Saxo names her three husbands, although the order of her first and second marriages is interchanged which appears impossible chronologically[14]. The necrology of Fulda records the death "1043 16 Kal Mar" of "Gisela imp"[15]. She married secondly ([1014]) Ernst Duke of Swabia [Babenberg] and thirdly Konrad II Herzog von Franken, who succeeded in 1024 as Konrad II King of Germany, and was crowned as Emperor Konrad I in 1027. Bruno & his wife had [two] children:

From the English Wikipedia page on Brun I, Count of Brunswick:,_Count_of_Brunswick

Brun (Latin Bruno; born around 975, died around 1010), was count in the Derlingau, the Nordthüringgau, the Hastfalagau, the Salzgau, the Gau Gretinge, and the Gau Mulbeze, with Brunswick as his residence. Brun was a member of the Brunones dynasty.

Brun's father is assumed to have been Count Liudolf (died 993). In 1002, Brun married Gisela of Swabia, who later became wife of the Emperor. Their oldest son was Liudolf (about 1003 – 1038).

In 990, Brun was a member of the Saxon army that supported Mieszko I, Duke of Poland, against Boleslaus II, Duke of Bohemia, in Silesia. Brun participated in the election for King of the Romans of 1002 (after the death of Otto III, Holy Roman Emperor) as a candidate and elector. When his own candidacy failed, he supported Herman II, Duke of Swabia, whose daughter he married in the same year. Brun had been considered a legitimate candidate because he was a male-line relative of Otto III.

Chapter 12. MARCH of FRISIA

The March of Frisia was presumably established by the kings of Germany as a response to the activities of Dirk III Count of Holland, whom Thietmar records (as "Dietrich the empress's nephew") attacked Adalbold Bishop of Utrecht in 1018, before his forces were attacked by the Frisians and suffered numerous casualties[815].

The precise date when the March was first established is not known. Liudolf von Braunschweig is the first person who appears with the title, from 1028.

His candidature was presumably approved because his paternal grandfather, Ekbert [I] "der Einäugige", held counties in Frisia (see the introductions to Chapters 8 and 9 above). According to Vanderkindere, Liudolf's son and grandson, both named Ekbert, were also installed in the march of Frisia[816]. Although the primary sources indicate that they held land in Frisia, their march was Meissen.

Heinrich Graf von Northeim, whose wife was heiress of the Brunswick family, was installed as Markgraf in Frisia in 1101 but was killed while trying to subdue the territory.

1. LIUDOLF von Braunschweig, son of BRUNO [I] [von Braunschweig] & his wife Gisela of Swabia ([1003/05]-23 Apr 1038).

  • The Annalista Saxo names "Liudolfus comes Saxonicus, filius Brunonis de Bruneswic et Gisle inperatricis", when recording his death[817].
  • His parentage is confirmed by the charter dated 1051 under which "Heinricus…Romanorum imperator augustus" donated "comitatum quem Brun eiusque filius noster frater Liutolfus nec non et eius filius Echbreht comites…in pagis Northduringen, Darlingen, Valen, Salthga, Grethe, Mulbeze" to the church of Hildesheim[818].
