The Duke of Bavaria is a historical title associated with the rulers of the region of Bavaria in Germany. The title has its origins in the early Middle Ages and has been held by various noble families, most notably the Wittelsbach dynasty. The dukes played a significant role in the political and cultural development of Bavaria, influencing its history and governance. Today, the title is largely ceremonial, with the last reigning duke, Ludwig III, having lost his throne in 1918 following the end of the German monarchy. The current head of the house is Maximilian, Duke of Bavaria, who represents the family's historical legacy and cultural contributions.
