Princess Olga of Greece and Denmark (Greek: Όλγα; 11 June 1903 – 16 October 1997) was a granddaughter of King George I of Greece, daughter of Prince Nicholas of Greece and Denmark and his wife Grand Duchess Elena Vladimirovna of Russia, and wife of Prince Paul, Regent of the Kingdom of Yugoslavia.
She has two sisters Princess Marina and Princess Elizabeth.
Princess Olga was born in Athens, Greece, on 11 June 1903. Her father was Prince Nicholas of Greece and Denmark, the third son of George I of Greece. Her mother was Grand Duchess Elena Vladimirovna of Russia, a granddaughter of Tsar Alexander II of Russia.
The family of Prince Nicholas was forced into exile when Olga was eleven, following the overthrow of the Greek monarchy, and later moved to Paris, whereas Olga stayed throughout Europe with her extended family, many of whom were far from rich.
Brought up without wealth, Princess Olga was engaged to Prince Frederick of Denmark in 1922. However, the marriage did not take place.
On 22 October 1923, she married Prince Paul of Yugoslavia in Belgrade.
Prince Paul and Princess Olga had three children:
-Prince Alexander of Yugoslavia (13 August 1924 - 12 May 2016)
-Prince Nicholas of Yugoslavia (29 June 1928 - 12 April 1954)
-Princess Elizabeth of Yugoslavia (born 7 April 1936)
On 9 October 1934, after the assassination of King Alexander I of Yugoslavia, Prince Paul was appointed regent of Yugoslavia until his cousin, Crown Prince Peter, attained his majority in September 1941.
During the Second World War, Prince Paul, Princess Olga, and their three children were arrested and given as prisoners to the British, who deported them to Greece, where they were guests of King George II, and then on to Egypt. From house arrest in Cairo, Paul and his family were moved to Kenya, where they arrived on 28 April 1941. There they were guests of Lord Erroll at Osserian, but remained under surveillance.
In August 1942, the accidental death of Prince George, Duke of Kent, left his widow, Princess Marina of Greece and Denmark, inconsolable, and the British government was persuaded to allow Olga to join her sister in England.
In June the 1943, British allowed the family to settle in South Africa, where several members of the Greek royal family were. In South Africa they were no longer treated as prisoners, but they were not formally released until June 1946, a year after the end of the war.
In 1948, Paul, Olga, and their three children were finally able to travel to Europe. Yugoslavia having fallen to the communists in 1945, they could not go home, and settled first in Switzerland and then in Paris, with frequent visits to London where she always made welcome by Marina, Duchess of Kent, and the rest of the British royal family; and Florence, where Paul owned a house, the Villa di Pratolino.
Widowed in 1976, Olga took to living in Britain. Her sister Marina having died in 1968, she stayed at Kensington Palace with Princess Alice, Duchess of Gloucester, and then later at Clarence House, in the household of HM the Queen Mother. She gained the reputation of being a demanding guest.
With old age, Olga's health suffered, but she continued to attend great occasions, such as the marriages of Alexander, Crown Prince of Yugoslavia(the only child of former King Peter II and his wife, Queen Alexandra of Greece and Denmark) in Spain on 1 July 1972, where she stood with Prince Alexander at the altar, as his mother Alexandra and grandmother were not well enough to attend.
In 1954, Olga's son Nicholas was killed in a road accident, and then in 1957 her mother died in Athens.
She also attended the wedding of Charles, Prince of Wales and Lady Diana Spencer in 1981.
Suffering at the end of her life from Alzheimer's disease, Olga spent several years in a hospital at Meudon, in the suburbs of Paris. In 1993, her daughter Princess Elizabeth set out to make a film-documentary about her with the help of a Serbian journalist. However, by then Olga was suffering from dementia, and her daughter's plan created a scandal. Her son Prince Alexander brought an action in the French courts against his sister, claiming $107,000 in damages and interest.
Princess Olga eventually died in Paris on 16 October 1997 and was buried beside her husband and her son Nicholas at the Bois-de-Vaux Cemetery, Lausanne, Switzerland.
On 28 September 2012, after the rehabilitation of Prince Paul by a new Serbian government, the remains of Olga, her husband, and their son Nicholas were exhumed and taken to Belgrade, for a ceremony in St Michael's Cathedral.
