Following the murder of King Gustavus III of Sweden (who belonged to the house of Oldenburg) in 1792, the throne passed to his son Gustavus IV Adolphus, who was then a minor. During his youth, he studied in France, and befriended general Napoleon Bonaparte. Returning home when he came of age, he staged a coup d'etat and became an absolute monarch, like his father. He sided with Napoleon, but switched sides in 1814, aided by amongst other general Bernadotte, who became a Swedish Count Bernadotte af Wisborg, and settled in Sweden after the defeat of Napoleon.
