Gustavus IV., King of Sweden (1778-1837), succeeded his father, Gustavus III., in 1792. Having made himself very unpopular by rashly engaging In a war with Russia which resulted in the loss of Finland, he was in 1809 deposed by his nobles in favour of his uncle Charles, Duke of Sudermania. After wandering under assumed names through several European countries, he at last settled at St. Gall, in Switzerland, where he died.
