The Dragons de la Garde impériale (Dragoons of the Imperial Guard) was a heavy cavalry unit formed by Napoleon I through the decree of April 15, 1806. The "dragoon" regiments of the line had distinguished themselves in the German Campaign of 1805, and therefore Napoleon decided to reorganize the cavalry of the Guard and create within it a regiment of dragoon guards. This regiment was colloquially known as the Dragons de l'Impératrice (Empress' Dragoons), in honor of Empress Joséphine. Following the Bourbon Restoration, they were renamed Corps royal des Dragons de France (Dragoons of France Royal Corps) but were disbanded shortly afterwards. The Empress' Dragoons were reformed during the Second Empire (1852-1870).
