Frederick I of Baden

Frederick I married Princess Louise of Prussia, daughter of Prince Wilhelm (later Emperor Wilhelm I), on 20 September 1856. This marriage strengthened ties between Baden and Prussia, influencing Baden's alignment in German politics.

Frederick I became Grand Duke of Baden on 5 September 1858, succeeding his father Leopold. His reign was noted for liberal reforms and constitutional governance.

Frederick I implemented a series of liberal reforms in Baden, including freedom of the press, religious tolerance, and judicial independence. These reforms made Baden one of the most progressive states in the German Confederation.

Frederick I supported the unification of Germany under Prussian leadership. He proclaimed the German Empire in Versailles on 18 January 1871, alongside other German monarchs, and Baden became a state within the empire.
