Another example was the line of self-proclaimed grand dukes (legally dukes) of Burgundy in the 15th century, when they ruled most of present-day north-eastern France as well as almost the entire Low Countries. They tried—ultimately without success—to create from these territories under their control a new unified country between the Kingdom of France in the west and the Holy Roman Empire (mainly present-day Germany) in the east. Philip III, Duke of Burgundy (reigned 1419–67) assumed the subsidiary, legally void style and title of "Grand Duke of the West" in 1435, having previously brought the Duchies of Brabant and Limburg as well as the counties of Holland, Zeeland, Friesland, Hainaut and Namur into his possession. His son and successor Charles the Bold (reigned 1467–77) continued to use the same style and title.
