Carinthia
Carinthia was a duchy of the Holy Roman Empire in the eastern Alps, covering parts of present-day Austria and Slovenia. Emperor Otto II separated it from Bavaria in 976, and in 1335 it passed to the Habsburgs.
The Treaty of Neuberg in 1379 assigned Carinthia, Styria and Carniola to Leopold III's branch of the family, which ruled Inner Austria from Graz. Carinthia remained under Habsburg rule through the dissolution of the Empire in 1806 and formed part of the Austrian Empire.
