Upper Styria
The first margraves from the House of Eppenstein appear in the late 10th century. Margrave Adalbero was also enfeoffed with the Duchy of Carinthia in 1011/12, but was deposed for alleged high treason by Emperor Conrad II in 1035. In 1053/54, the margravial lands were pillaged by the forces of the deposed Bavarian duke Conrad I and Duke Welf of Carinthia. From 1056 onwards, the march was ruled by the Chiemgau count Ottokar I and his descendants of the Otakar dynasty, who were first mentioned as "Margraves of Steyr" in 1074. In 1122, they also inherited the allodial possessions of their Eppenstein predecessors in Upper Styria.
