March of Carinthia

The March of Carinthia (Markgrafschaft Karantanien) was a frontier district (march, or margraviate) of the Carolingian Empire. It was created in 889, by king Arnulf of East Francia, encompassing the region of Carantania. Before it became a march, it was organized as a county, since 828 under the Bavarian jurisdiction. In 976, the march of Carinthia was raised into a Duchy.^[1][2]

In the meantime, a new Carinthian "transalpine" march (that is, a march beyond the mountains, defending the Carinthia proper) was created in eastern regions, on the river Mur (thus also known as the march on the Mur), and that new province was later transformed into the March of Styria.
