Kingdom of Burgundy
The Kingdom of Burgundy, known from the 12th century as Kingdom of Arles, also referred to in various context as Arelat, Kingdom of Arles and Vienne, or Kingdom of Burgundy-Provence, was a realm established in 933 by the merger of the kingdoms of Upper and Lower Burgundy under King Rudolf II. It was incorporated into the Holy Roman Empire in 1033 and from then on was one of the empire's three constituent realms, together with the Kingdom of Germany and the Kingdom of Italy. By the mid-13th century at the latest, however, it had lost its concrete political relevance.
