Sometimes the flag of the Lorraine region is identified as the flag of Lotharingia. But I didn't found any proof of that.

The paint made by Albrech Dürer (~1500AD),

show only the western and the eastern Frankish realms, but the middle realm, Lotharingia isn't present...

It seems it's like if Lotharingia has never really existed as a real state. I know it was nibbled by the two others, but that doesn't explain why I don't found any clue of the CoA nor the flag...

  • @Semaphore 955-965, well one century, I think it's a significant timescale. Enough to create a CoA/flag... when you know that some rulers without states had CoA so how can this is possible ? – The Unholy Metal Machine Apr 9 '15 at 15:10
  • @Semaphore sry my bad, I wanted to write 855-965. In 870 the treaty of Meerssen split Lotharingia, but Loth. was reunified as a duchy ~880-903 – The Unholy Metal Machine Apr 9 '15 at 15:41

    Lothair I's kingdom ended long before heraldry is believed to have begun. A smaller Lotharingia became part of the Kingdom of Germany c. 939. It soon divided into the duchies of upper and lower Lotharingia & later into other fiefs. Eventually the coat of arms of the Duchy of upper Lorraine became or, a bend gules with three eaglets argent, and the arms of the Duchy of lower Lorraine became gules, a fess argent, so the quartered arms of the 2 Lorraines could be used as attributed arms of Lotharingia. Lower Lorraine was renamed Brabant & had arms sable a lion rampant or. – M.A. Golding Jul 23 '16 at 22:45

    The Unholy Metal Machine - expecting a medieval coat of arms in Lothair I's Lotharingia would be like expecting a Guttenburg printing press or a suit of gothic plate armor there - an anacchronism. You can always posthumously attribute the quartered arms of Upper Lorraine and Lower Lorraine to Lotharingia, like the heraldic artists of Emperor Maximilian one used the arms of the Duchy of Burgundy (reversed) and the small Duchy of Burgundy for the attributed arms of the Kingdom of Burgundy. – M.A. Golding Jul 23 '16 at 22:54

    The Unholy Metal Machine - To amplify, various publications of Maximilian I depict the arms of the small Duchy of Burgundy (in western switzerland) as or, a crown azure. The old arms of the French Duchy of Burgundy are bendy of six or and azure, a border gules. The writers and illustrators of Maximilian's publications put the arms of small Burgundy in the 1st and 4th quarters and old French Burguny (but bendy sinister) in the 2nd and 3rd quarters and the arms of the County of Habsburg in the center inescutcheon, feeling authorized by the fact that the emperor was the king of Burgundy. – M.A. Golding Jul 23 '16 at 23:05
