Mieszko II Lambert
Margrave Herman became a loyal supporter of King Henry's Salian successor Conrad II. In 1029, he was appointed count in the Saxon Hassegau and the adjacent Gau Chutizi in the March of Merseburg. He sent his forces against the Polish king Mieszko II Lambert to reconquer the Polish-occupied territories, sealed by the 1033 Treaty of Merseburg. Herman also fought against the Thuringian count William III of Weimar, and quarrelled with Bishop Thietmar of Merseburg. In his later years, he left the rule to his younger brother Eckard II, who succeeded Herman upon his death in 1038.
