Nellenburg

Nellenburg was a landgraviate in Hegau, centred on Stockach between the Swabian Alb and Lake Constance. In 1337 it was held by a branch of the counts of Veringen, who had united Nellenburg with Hegau.

When the line died out in 1422, the lords of Tengen inherited the landgraviate and sold it to the Habsburgs in 1465. Stockach, the seat of its high court, survived a Three Leagues siege in the Swabian War of 1499. Nellenburg passed from Further Austria to Württemberg in 1805 and to Baden in 1810.
