976 CE
The March of Carinthia is raised to a Duchy in 976, and a new Carinthian march (that is, a march defending the Carinthian duchy) is created from the adjacent territory in the east up to the Mur, Mürz and Enns rivers, which had in 955 been annexed by King Otto I after the Battle of Lechfeld.
It will become the later March of Styria, so named for the town of Steyr, the residence of the margraves in the eleventh century.
