The Duke of Saxony was a noble title in the historical region of Saxony, located in present-day Germany. The title was held by various rulers from the early medieval period until the 19th century. The Dukes played a significant role in the political landscape of the Holy Roman Empire, often engaging in alliances and conflicts with other noble houses. The title of Duke of Saxony was eventually replaced by the title of King of Saxony in the 19th century, as the region became a kingdom. The last Duke, Albert the Bold, was known for his contributions to the arts and culture in Saxony, leaving a lasting legacy in the region.
