The Grand Duchy of Baden was a historical state in southwestern Germany, established in 1806 and lasting until 1918. It was part of the German Empire and was known for its diverse landscapes, including the Black Forest and the Rhine River. The capital city was Karlsruhe, which served as a cultural and administrative center. Baden was notable for its progressive policies, including early adoption of civil rights and education reforms. The region was also famous for its thermal baths, particularly in Baden-Baden, which attracted visitors seeking health treatments. After World War I, the grand duchy was dissolved, becoming part of the newly formed Weimar Republic.
