Princess Margaret of Connaught was Crown Princess of Sweden as the first wife of the future King Gustaf VI Adolf. She was the elder daughter of Prince Arthur, Duke of Connaught, third son of Queen Victoria of the United Kingdom, and his wife Princess Louise Margaret of Prussia. Known in Sweden as Margareta, her marriage produced five children.

Gustaf VI Adolf 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, and shortly before his death, he gave his approval to constitutional changes which removed the Swedish monarchy's last political powers. He was a lifelong amateur archeologist particularly interested in Ancient Italian cultures.
