Olav V (ˈûːlɑːv dɛn ˈfɛ̂mtə; born Prince Alexander of Denmark; 2 July 1903 – 17 January 1991) 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 ('The People's King'). In a 2005 poll by the Norwegian Broadcasting Corporation, Olav was voted "Norwegian of the Century".
Olav was born as Prince Alexander Edward Christian Frederik in Appleton House on the royal Sandringham Estate, Flitcham, United Kingdom. His parents were Prince Carl, second son of Crown Prince Frederick of Denmark (later King Frederick VIII), and Princess Maud, youngest daughter of King Edward VII of the United Kingdom, who was the eldest son of Britain's Queen Victoria. In 1905, Carl was elected King of Norway and took the name Haakon VII. On the day Haakon was crowned, he gave his two-year-old son the Norwegian name Olav after Olaf Haakonsson, king of Norway and Denmark.
Olav was thus the first heir to the throne since the Middle Ages to have been raised in Norway. Unlike his father, who was a naval officer, Olav chose to complete his main military education in the army. He graduated from the three-year Norwegian Military Academy in 1924, with the fourth best score in his class. Olav then went on to study jurisprudence and economics for two years at Balliol College, Oxford.
