Hermann Billung
Hermann Billung (900 or 912 – 27 March 973) was the margrave of the Billung March from 936 until his death. The first of the Saxon House of Billung, Hermann was a trusted lieutenant of Emperor Otto I. Though never Duke of Saxony himself, while Otto (who was the enthroned duke of Saxony) was in Italy from 961 until 972, Hermann served as Otto's personal representative in governing Saxony. Towards the end of his life, Hermann was the effective duke in all but name. Hermann died in 973, just two months before Otto's own death. Hermann's son Bernard I was named as the new duke of Saxony by Otto I's son Otto II. Life
Hermann was probably the son of Billung. He was the younger brother of the Saxon count Wichmann the Elder. Hermann is generally counted as the first Billung duke (Herzog) of Saxony, but his exact position is unclear. The ducal Ottonian dynasty had risen to German royalty with the accession of Henry the Fowler in 919 and had to concentrate on countrywide affairs. At least in 961, when King Otto I of Germany marched against the Kingdom of Italy for the second time, he made Hermann the administrator (procurator regis) in his Saxon lands. When in 936 King Otto I had ascended the throne, he appointed Hermann a margrave (princeps militiae), granting him the Saxon march north of the Elbe river. His Billung March stretched from the Limes Saxoniae in the west along the Baltic coast to the Peene River in the east, roughly corresponding with the later Mecklenburg region. Otto thereby disregarded the claims of Hermann's elder brother Count Wichmann, a brother-in-law of Queen Dowager Matilda. Wichmann in turn joined the unsuccessful rebellion of King Otto's half-brother Thankmar and Duke Eberhard of Franconia in 938. Having more autonomy than the contemporary margrave Gero ruling over the adjacent Marca Geronis in the south, Hermann exacted tribute from the local Polabian Slavs of the Obotrite tribal federation. Upon his brother's death in 944, he also became count in the Saxon Bardengau around the town of Lüneburg, where he founded the monastery of St Michael in that city. He again disregarded the inheritance claims raised by his nephews Wichmann the Younger and Egbert the One-Eyed. In 953 both joined the countrywide rebellion started by King Otto's younger brother Duke Liudolf of Swabia, which only collapsed due to the massive invasion of Hungarian forces. During this grave crisis, the king, who was also Duke of Saxony, began entrusting more and more of his authority in the Saxon lands to Hermann during his absences. However, Hermann was never named dux in royal documents. Instead, he is named as a military leader, count, and margrave. His position was solidified, when on 2 February 962 King Otto was crowned Holy Roman Emperor in Rome by Pope John XII. Hermann was received like a king by Archbishop Adalbert of Magdeburg in 972, which even annoyed the emperor. He may have been the founder of the Hermannsburg locality in the Lüneburg Heath, first mentioned in 1059. Hermann died in Quedlinburg. His son Bernard inherited and strengthened his father's position and managed to be recognized as duke. Descendants
Hermann Billung perhaps was married twice: According to the chronicles of St Michael's Abbey in Lüneburg, a Countess Oda died on 15 March in an unknown year after 973, the Xanten annals noted the death of one Ode, spouse of Duke Hermann, on the same day. She probably was related to the royal Ottonian dynasty; Henry the Fowler's grandmother was named Oda (herself a member of the Billung dynasty), which was also the name of his sister. A second wife Hildesuith or Hildegard of Westerburg is mentioned in the chronicles, but her relation to Oda remains unclear. Hildegard was also the name of the spouse of Hermann's son Bernard. The name of Hermann's granddaughter Oda of Meissen suggests that Oda was the mother of his children. He had five children:
Bernhard I (died 1011), Duke of Saxony
Liutger (died 26 February 1011), attested in 991, buried in St. Michaels in Lüneburg, married Emma of Lesum (died 3 December 1038), buried in the Bremen Cathedral.
