Fürstenberg-Heiligenberg

Fürstenberg-Heiligenberg was a county and later a principality in southern Baden-Württemberg, Germany, located in the historical territory of Heiligenberg. It was created as a partition of Fürstenberg-Baar in 1559, and it suffered one partition between itself and Fürstenberg-Donaueschingen in 1617.
When Herman Egon of Fürstenberg-Heiligenberg was elevated to the estate of imperial princes in 1664, Fürstenberg-Heiligenberg was raised to a principality and existed as an imperially immediate territory. It inherited Fürstenberg-Donaueschingen in 1698, but following the extinction of its branch in 1716, it was inherited by Fürstenberg-Fürstenberg.
