Hermann Billung

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.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.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.
