Ulrich I, Count of Württemberg

Ulrich I (c. 1222 – 25 February 1265), nicknamed the Founder (German: der Stifter), was Count of Württemberg from 1241 until his death in 1265.

The historian Hansmartin Decker Hauff labelled Ulrich as a son of Hermann of Württemberg and Irmengard of Ulten.

The argument between Emperor Frederick II and the Popes Gregory IX and Innocent IV had effects on conditions in the duchy of Swabia, of which Württemberg was a part.

Conradin's guardian, Louis II, Duke of Bavaria, annexed the territories that Ulrich had gained from defeating Conrad IV, to Swabia.

Ulrich was forced to concentrate on the middle Neckar valley as the basis of the county of Württemberg.
