Saxe-Weissenfels was a historical principality in Germany, part of the larger Duchy of Saxe. Established in the early 17th century, it was ruled by the House of Wettin. The principality was known for its cultural contributions and its role in the political landscape of the Holy Roman Empire. The capital of Saxe-Weissenfels was the town of Weissenfels, which served as an important center for trade and administration. The principality was dissolved in the 19th century, following the restructuring of German territories, but its legacy remains in the region's history and architecture.
