CHARLES XV. (1826-72). King of Sweden and Norway from 1859 to 1872. He succeeded his father, Oscar I., who was a son of Charles XIV. John (q.v.). The rule of Charles was liberal and popular. The most important event was the change (in 1866) in the constitution of the Parliament, which has since consisted of two chambers, one elected by the provincial representatives and the other by the people. He had a taste for literature and art, and published a volume of poems. In 1850 he married Louisa, daughter of the King of the Netherlands, by whom he had one daughter, who became the wife of Prince Frederick of Denmark. He died September 18, 1872.
