Gustaf VI Adolf (Oscar Fredrik Wilhelm Olaf Gustaf Adolf; 11 November 1882 – 15 September 1973) was King of Sweden from 29 October 1950 until his death. He was the eldest son of King Gustaf V and his wife, Victoria of Baden, and had been Crown Prince of Sweden for the preceding 43 years in the reign of his father. Not long before his death at age 90, he approved the constitutional changes which removed the Swedish monarchy's last nominal political powers. He was a lifelong amateur archeologist particularly interested in Ancient Italian cultures.
