The Grand Duchy of Baden, also known as the Baden Palatinate, was a state in south-west Germany on the east bank of the Rhine. It existed as a sovereign state between 1806 and 1871 and as part of the German Empire from 1871 until 1918.

The Kingdom of Württemberg was a German state that existed from 1805 to 1918, located within the area that is now Baden-Württemberg. The kingdom was a continuation of the Duchy of Württemberg, which existed from 1495 to 1805. Prior to 1495, Württemberg was a county in the former Duchy of Swabia, which had dissolved after the death of Duke Conradin in 1268.
