Who married Friederike von Baden?

Prinzessin Friederike Dorothea Wilhelmine von Baden (* 12. März 1781 in Karlsruhe; † 25. September 1826 in Lausanne) war als Frau des schwedischen Königs Gustav IV. Adolf von 1797 bis 1809 Königin von Schweden.

Gustav IV Adolf or Gustav IV Adolph (1 November 1778 – 7 February 1837) was King of Sweden from 1792 until he was deposed in a coup in 1809. He was also the last Swedish monarch to be the ruler of Finland.

The occupation of Finland in 1808–09 by Russian forces was the immediate cause of Gustav Adolf's overthrow, violently initiated by officers of his own army. Following his abdication on 29 March 1809, an Instrument of Government was hastily written, which severely circumscribed the powers of the monarchy. The "Instrument" was adopted in 1809 on 6 June, the National Day of Sweden now as well as in his time. It remained in force until replaced in 1974. The crown, now with strictly limited powers, passed to Gustav Adolf's uncle Charles XIII.
