The Bavarian Dukes were rulers of the region of Bavaria in what is now Germany. They governed from the early Middle Ages until the late 13th century, playing a crucial role in the development of the area. The dukes were often involved in regional politics and conflicts, and their rule helped shape the cultural and social landscape of Bavaria. One of the most notable Bavarian Dukes was Henry the Lion, who ruled in the 12th century. His reign marked a period of expansion and influence for Bavaria. The dukes eventually lost power to the Wittelsbach family, who became the Electors and later Kings of Bavaria, continuing the region's legacy.
