Saxony-Weissenfels was a small principality in Germany that existed from the early 17th century until the late 18th century. It was part of the larger region of Saxony and was established in 1657 when John George I of Saxony divided his territory among his sons. The capital of the principality was the town of Weissenfels, which became an important cultural and administrative center. The principality was known for its Baroque architecture and its role in the Saxony court. It was ruled by the House of Wettin, a prominent dynasty in German history. In 1746, Saxony-Weissenfels was absorbed into the larger Duchy of Saxony, marking the end of its status as an independent principality.
