 According to this theory, the Swedish flag was created during the reign of King Charles VIII, who also introduced the coat of arms of Sweden in 1442.The national coat of arms is a combination of King Albert's coat of arms of 1364 and King Magnus III's coat of arms of 1275, and is blue divided quarterly by a golden cross pattée.Other historians claim that the Swedish flag was blue with a white cross before 1420, and became blue with a golden cross only during the early reign King Gustav I, who deposed King Christian II in 1521.
