Olav V (2 July 1903 – 17 January 1991) was the king of Norway from 1957 until his death.
A member of the House of Schleswig-Holstein-Sonderburg-Glücksburg, Olav was born in the United Kingdom as the son of Prince Carl of Denmark and Princess Maud of the United Kingdom and given the names Alexander Edward Christian Frederik. He became Crown Prince and heir-apparent to the throne of Norway when his father was elected king in 1905. He was the first heir to the Norwegian throne to be brought up in Norway since Olav IV, and his parents made sure he was given as Norwegian an upbringing as possible. In preparation for his royal duties, he attended both civilian and military schools. In 1929, he married his first and second cousin Princess Märtha of Sweden. During World War II his leadership was much appreciated and he was appointed Norwegian Chief of Defence in 1944. Succeeding to the throne in 1957, he enjoyed a very high level of popularity and respect throughout his reign, in which he was able to balance regality and approachability. Upon his death in 1991, the Norwegian public displayed a great demonstration of mourning. At his death, he was the last surviving grandchild of Edward VII of the United Kingdom and Alexandra of Denmark.
Born in Appleton House, Flitcham, Sandringham estate, Norfolk, United Kingdom to Prince Carl of Denmark and Princess Maud of Wales, (daughter of King Edward VII of the United Kingdom), he was given the names and title of Alexander Edward Christian Frederik, Prince of Denmark. He was given the name Olav when his father became King Haakon VII of Norway in 1905.
