Lorraine

By the Treaty of Verdun in 843, the empire of Charlemagne was divided in three parts: Ludwig the German received Eastern Franconia; Charles the Bald, Western Franconia; and Lothair I, the strip of land lying between the two and reaching from the North Sea to the Rhone, with Italy in addition. After the death of Lothair I, in 855, Italy passed to his son Lothair II, who gave his name to the district henceforth known as Lotharii Regnum - Lotharingen, Lothringen, or Lorraine.
