Page "History of Austria" Paragraph 27

Emperor Rudolf I of Habsburg gave Austria to his sons in 1278.

Austria was ruled by the Habsburgs for the next 640 years ( 13th century – 1918 ).

In the 14th and 15th centuries, the Habsburgs began to accumulate other provinces in the vicinity of the Duchy of Austria, which remained a small territory along the Danube, and Styria, which they had acquired from Ottokar along with Austria.

Carinthia and Carniola came under Habsburg rule in 1335, Tyrol in 1363.

These provinces, together, became known as the Habsburg Hereditary Lands, although they were sometimes all lumped together simply as Austria.
