The Grand Duchy of Berg (German: Großherzogtum Berg), also known as the Grand Duchy of Berg and Cleves, was a territorial grand duchy established in 1806 by Napoleon after his victory at the Battle of Austerlitz (1805) on territories between the French Empire at the Rhine river and the German Kingdom of Westphalia.
