Grand Duchy of Hesse

State in western Germany (1806–1918)

The Grand Duchy of Hesse and by Rhine (German: Großherzogtum Hessen und bei Rhein) was a grand duchy in western Germany that existed from 1806 to 1918. The grand duchy originally formed from the Landgraviate of Hesse-Darmstadt in 1806 as the Grand Duchy of Hesse (German: Großherzogtum Hessen). It assumed the name Hesse and by Rhine in 1816 to distinguish itself from the Electorate of Hesse, which had formed from the neighbouring Landgraviate of Hesse-Kassel. Colloquially, the grand duchy continued to be known by its former name of Hesse-Darmstadt.
