Free Imperial City of Buchhorn

1275 CE – 1802 CE (approx.) · capital Buchhorn

Tiny imperial city on the north shore of Lake Constance that was merged with a neighbouring priory to form the town of Friedrichshafen in 1811.

Origins

Buchhorn grew on the north shore of Lake Constance as a fishing and market settlement under the counts of Buchhorn and later the Guelphs and Hohenstaufen. After the fall of the Hohenstaufen it was recognised as an imperial city by Rudolf I around 1275.

Rule and society

Buchhorn was one of the smallest imperial cities, with a council of burghers and a tiny territory. It lived from fishing, lake shipping and trade across the lake to Switzerland, and its market served the surrounding countryside. It remained Catholic and depended on alliances with other Swabian cities and on Austrian goodwill.

Decline and legacy

Bavaria annexed Buchhorn in 1802 and passed it to Württemberg in 1810. In 1811 King Frederick I of Württemberg merged it with the neighbouring Hofen priory to create Friedrichshafen, later the home of the Zeppelin airships.
