The Duchy of Palatinate-Zweibrücken was a historical territory in what is now southwestern Germany. Established in the 16th century, it was part of the larger Palatinate region and served as a significant political entity during the Holy Roman Empire. The duchy was known for its contributions to the arts and culture, particularly during the Renaissance. The capital of the duchy was Zweibrücken, which became an important center for administration and governance. The duchy experienced various territorial changes and was eventually absorbed into the Duchy of Bavaria in the 18th century, marking the end of its independent status.
