Landgraviate of Klettgau

1408 CE – 1806 CE (approx.) · capital Tiengen

A small landgraviate on the upper Rhine between the Black Forest and Schaffhausen, ruled by the counts of Sulz and then the Schwarzenbergs.

Origins

The Klettgau, a fertile district north of the Rhine near Schaffhausen, had been held as a landgraviate by the counts of Habsburg-Laufenburg. In 1408 it passed by marriage to the counts of Sulz, who ruled it from Tiengen.

Rule and society

The counts of Sulz were also hereditary judges of the imperial court at Rottweil. Klettgau's peasants joined the Peasants' War of 1525 and were defeated. Losses to Zürich and Schaffhausen reduced the territory, and when the Sulz line died out in 1687 it passed by marriage to the Principality of Schwarzenberg, whose princes ruled it from afar through officials. It remained Catholic.

Decline and legacy

In 1806 Klettgau was mediatised and placed under the Grand Duchy of Baden, which later bought out the Schwarzenbergs' remaining rights. The district now lies mainly in Baden-Württemberg, with its southern part in the Swiss canton of Schaffhausen.
