Lotharingia named the lands originally awarded to
Lothair, King of Lotharingia (reigned 855 - 869) and named after him. These lands, the northern component of the territories of King Lothair's father, the emperor
Lothair as at 843, comprised (broadly speaking) the Netherlands and Lorraine (the
Rhine valley). Soon subdivided, and long the source of territorial contention between French and German super-states, Lotharingia survives today principally in the name derived from it:
Lorraine.
