Lothair died in 869 and the kingdom fragmented into duchies and counties. By 925 Otto I of Germany conquered the area. He created the duchy of Lotheringia and gave it to his brother Bruno. Bruno divided the duchy into Upper and Lower Lorraine. In time Lower Lorraine became a patchwork of duchies, counties and lordships. Upper Lorraine fared a little better and became our duchy of Lorraine.
