The Duchy of Saxe was a historical region in what is now modern-day Germany. It was part of the larger area known as Saxony and was established in the early Middle Ages. The duchy played a significant role in the political landscape of the Holy Roman Empire, with various rulers overseeing its development and influence. Throughout its history, the Duchy of Saxe was divided into several smaller territories, including Saxe-Weimar and Saxe-Coburg. These divisions often led to conflicts and alliances with neighboring states. The duchy eventually became part of the Kingdom of Saxony in the 19th century, further shaping the region's identity.
