When Herman Egon of Fürstenberg-Heiligenberg was elevated to the estate of imperial princes (Reichsfürstenstand) 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.
