The term "Duchess of Bavaria" refers to the title held by the female members of the ruling family of the historical region of Bavaria in Germany. This title has been associated with various noblewomen throughout history, often linked to the House of Wittelsbach, which ruled Bavaria for centuries. The duchess typically played a significant role in the political and social affairs of the region. In modern times, the title is often used in a ceremonial context, as Bavaria is now part of the Federal Republic of Germany. The last reigning duchess was Therese of Bavaria, who became known for her contributions to Bavarian culture and society. Today, the title remains a symbol of the region's rich history.
