Dukes in Italy, Germany and Austria

The following is a list of historic duchies in Europe:

The Habsburg dukes came to style themselves Archdukes.

The Duchy of Bohemia became Kingdom of Bohemia in 1212.

Although the titled aristocracy of Germany no longer holds a legal rank, nearly all ducal families in Germany continued to be treated as dynastic (i.e., "royalty") for marital and genealogical purposes after 1918. Some maintain dynastic traditions that are reflected in roles they still play in high society, philanthropy and Germany's version of local "squirearchy".

At first, the highest nobles – de facto equal to kings and emperors – were the Dukes of the stem duchies:

Later, the precedence shifted to the prince-electors, the first order amongst the princes of the empire, regardless of the actual title attached to the fief. This college originally included only one Duke, the Duke of Saxony. The ducal title, however, was not limited by primogeniture in the post-medieval era. All descendants in the male line, including females, shared the original title, but each male added as a suffix the name of his inherited domain to distinguish his line from that of other branches. From the 19th century, some cadets of the kingly houses of Bavaria and Württemberg, and all those of the grand-ducal houses of Mecklenburg-Schwerin, Mecklenburg-Strelitz and Oldenburg, took the ducal prefix as their primary style instead of that of Prince (Prinz).
