Olav V was King of Norway from 1957 until his death in 1991.
Olav was the only child of King Haakon VII of Norway and Maud of Wales. He became heir apparent to the Norwegian throne when his father was elected King of Norway in 1905. He was the first heir to the Norwegian throne to be brought up in Norway since Olav IV in the fourteenth century, and his parents made sure he was given as Norwegian an upbringing as possible. In preparation for his future role, he attended both civilian and military schools. In 1929, he married his first cousin Princess Märtha of Sweden. During World War II his leadership was much appreciated and he was appointed Norwegian Chief of Defence in 1944. Olav became king following the death of his father in 1957.
Owing to his considerate, down-to-earth style, King Olav was immensely popular, resulting in the nickname Folkekongen. In a 2005 poll by the Norwegian Broadcasting Corporation, Olav was voted "Norwegian of the Century".
