Von Zimmern

Their original domain was in the Black Forest, in part of the modern Rottweil district.

Their original castle was Herrenzimmern near Bösingen (ruined since the 17th century).

In 1415, the von Zimmern acquired Wildenstein Castle.

In 1488, the escalation of the Werdenberg feud, Johannes Werner the elder fell under imperial ban and most of the von Zimmern possessions was given to the Werdenberger lords of Sigmaringen; the possessions were eventually regained, by Johannes Werners's son, Johannes Werner the younger, in 1503.

The family reached the peak of its influence in 1538, when they were elevated to the rank of count (Graf).
