誰が Olav V of Norway と結婚しましたか？

Olav V (Norwegian: Olav den femte, Norwegian pronunciation: [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 born at Sandringham House in England, the only child of Prince Carl of Denmark and Princess Maud of Wales. He became heir apparent to the Norwegian throne when his father was elected King Haakon VII of Norway in 1905. He was the first heir to the Norwegian throne to be brought up in Norway since Olav IV in the 14th century, and his parents made sure that 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.

His considerate, down-to-earth style made Olav 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".

Princess Märtha of Sweden (Märtha Sofia Lovisa Dagmar Thyra; 28 March 1901 – 5 April 1954) was Crown Princess of Norway as the spouse of the future King Olav V from 1929 until her death in 1954. As Olav only became king in 1957, Märtha never became Queen of Norway. Her son, Harald V, is the current king of Norway. Princess Märtha was also an elder sister of Queen Astrid of Belgium and a maternal aunt of Grand Duchess Joséphine-Charlotte of Luxembourg and Kings Baudouin and Albert II of Belgium.

In 1940, Crown Princess Märtha and her family were immersed in World War II as Germany invaded Norway. After escaping to her home country of Sweden, and then being evacuated to America by President Franklin D. Roosevelt, she effectively advocated for Norway and did fundraising until the end of the war. In 1942, King Haakon VII of Norway, Märtha's father-in-law, invested her as a Dame Grand Cross of the Royal Norwegian Order of Saint Olav.
