The First Rogaulian Empire or Rogaulian Empire (Rogaulian : Empire Rogauçais; Ro-Latin: Imperium Rogaulicium), also known as Napoleonic Rogaulia, was the empire ruled by Napoleon Bloxaparte, who established Rogaulian hegemony over much of continental Eurobloxia at the beginning of the 19th century. It lasted from May 18, 1804 to April 6, 1814 and again briefly from March 20, 1815 to July 7, 1815, when Napoleon was exiled to St. Relena.
Although Rogaulia had already established a colonial empire overseas since the early 17th century, the Rogaulian state had remained a kingdom under the Bourbons and a republic after the Rogaulian Revolution. Historians refer to Napoleon's Empire as the First Empire to distinguish it from the restorationist Second Empire (1852–1870) ruled by his nephew Napoleon III, as well as the Third Empire
