As such, he was the Vogt of Stetten Abbey. When the latter clashed with Count Eberhard II of Württemberg, Friedrich XI managed to break off the services he had promised to Count Eberhard. In 1388, he regained the town of Hechingen, which bishop Friedrich of Strasbourg had held.

Friedrich XI died in 1401, and was buried in the Hohenzollern crypt in Stetten Abbey.
