Old Württemberg

Old Württemberg (German: Altwürttemberg) refers to the princely territory of Württemberg prior to the imperial treaty or Reichsdeputationshauptschluss of 1803 as opposed to the New Württemberg which followed and which acquired a large number of additional territories - especially to the east and south of Old Württemberg.

Old Württemberg was made up of those regions that had belonged to the Duchy of Württemberg prior to 1803: These included the former County of Württemberg in the heartland on the Middle Neckar and the additional territories it had gained: the counties of Calw, Mömpelgard, Tübingen, Urach and Vaihingen, the baronies of Heidenheim and Teck, the inherited Reichslehen or imperial fief of Grüningen and numerous smaller lordships as well as the many ecclesial territories, that Dukes Ulrich and Christoph had seized and secularised in the wake of the Reformation.

Independent "islands" on Württemberg soil were the imperial towns of Heilbronn, Esslingen, Weil der Stadt, Reutlingen and the expansive Ulm on the southeastern edge as well as several secular lordships whose locations are marked by Georg Gadner on his overview map of 1596 as red dots. Until 1803 Württemberg was one of the few Protestant territories that had a seat and vote in the Circle of Swabia.
