The March of Styria (Latin: Marchia Stirensis; German: Steiermark) was a southeastern frontier march of the Holy Roman Empire, encompassing various regions around the river Mur. Created sometime before 970, it was broken off the larger March of Carinthia, itself a march of the Duchy of Bavaria, and established as a buffer zone against the Hungarian invasions. In 976, it was transferred to the jurisdiction of the newly created Duchy of Carinthia. It became an Imperial State in its own right, when it was elevated to the Duchy of Styria in 1180.[1][2]
