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 in 1973. He was the eldest son of Gustaf V and his wife, Victoria of Baden. Before Gustaf Adolf ascended the throne, he had been crown prince for nearly 43 years during his father's reign. As king, he gave his approval shortly before his death to constitutional changes which removed the Swedish monarchy's last nominal political powers. He was a lifelong amateur archeologist particularly interested in Ancient Italian cultures.
