Grand Duchy of Baden

The Grand Duchy of Baden (German: Großherzogtum Baden) was a German polity on the east bank of the Rhine. It originally existed as a sovereign state from 1806 to 1871 and later as part of the German Empire until 1918.

The duchy's 12th-century origins were as a margraviate that eventually split into two, Baden-Durlach and Baden-Baden, before being reunified in 1771. The territory grew and assumed its ducal status after the dissolution of the Holy Roman Empire but suffered a revolution in 1848, whose demands had been formulated in Offenburg the previous year at a meeting now considered the first-ever democratic program in Germany. With the collapse of the German Empire it became part of the Weimar Republic under the name Republic of Baden.
