Saxe-Weimar-Eisenach

Saxe-Weimar-Eisenach (German: Sachsen-Weimar-Eisenach) was a German state, created as a duchy in 1809 by the merger of the Ernestine duchies of Saxe-Weimar and Saxe-Eisenach, which had been in personal union since 1741. It was raised to a grand duchy in 1815 by resolution of the Congress of Vienna. In 1903, it officially changed its name to the Grand Duchy of Saxony (German: Großherzogtum Sachsen), but this name was rarely used. The grand duchy came to an end in the German Revolution of 1918–19 with the other monarchies of the German Empire.
