House of Gorizia
In the 14th century the Habsburgs began to accumulate other provinces in the vicinity of the Duchy of Austria, which had remained a small territory along the Danube, and Styria, which they had acquired with Austria from Ottokar. In 1335 Albert II inherited the Duchy of Carinthia and the March of Carniola from the then rulers, the House of Gorizia.
