Charles IX of Sweden

Charles IX, also Carl, reigned as King of Sweden from 1604 until 1611. He was the youngest son of King Gustav I and his second wife, Margaret Leijonhufvud, the brother of King John III and half-brother of King Erik XIV, and the uncle of Sigismund, who became king both of Sweden and of Poland. By his father's will, Charles received, by way of appanage, the Duchy of Södermanland, which included the provinces of Närke and Värmland; but he did not come into actual possession of them till after the fall of Eric and the succession to the throne of John in 1569.
