On returning to Greece a few years later, her husband was blamed in part for the country's defeat in the Greco-Turkish War (1919–1922), and the family was once again forced into exile until the restoration of the Greek monarchy in 1935.

She stayed in Athens during the Second World War, sheltering Jewish refugees, for which she is recognised as "Righteous Among the Nations" by Israel's Holocaust memorial institution, Yad Vashem.

In 1988, her remains were transferred from a vault in her birthplace, Windsor Castle, to the Church of Mary Magdalene at the Russian Orthodox convent of the same name on the Mount of Olives in Jerusalem.

She had six godparents: her three surviving grandparents, Grand Duke Louis IV of Hesse, Prince Alexander of Hesse and by Rhine, and Julia, Princess of Battenberg; her maternal aunt Grand Duchess Elizabeth Feodorovna of Russia; her paternal aunt Princess Marie of Erbach-Schönberg; and her maternal great-grandmother Queen Victoria.

[7] A few weeks before her 16th birthday, she attended Queen Victoria's funeral in St George's Chapel, Windsor Castle, and shortly afterward she was confirmed in the Anglican faith.

[11] The bride and groom were closely related to the ruling houses of the United Kingdom, Germany, Russia, Denmark, and Greece, and their wedding was one of the great gatherings of the descendants of Queen Victoria and King Christian IX held before World War I.

[13] On their return to Greece, Prince and Princess Andrew found the political situation worsening, as the Athens government had refused to support the Cretan parliament, which had called for the union of Crete (still nominally part of the Ottoman Empire) with the Greek mainland.

A group of dissatisfied officers formed a Greek nationalist Military League that eventually led to Prince Andrew's resignation from the army and the rise to power of Eleftherios Venizelos.

[3] During World War I, her brother-in-law King Constantine I of Greece followed a neutrality policy despite the democratically elected government of Venizelos supporting the Allies.

The naval career of Princess Andrew's father, Prince Louis of Battenberg, had collapsed at the beginning of the war in the face of anti-German sentiment in Britain.

At the request of King George V, he relinquished the Hessian title Prince of Battenberg and the style of Serene Highness on 14 July 1917, and anglicized the family name to Mountbatten.

At the end of the war the Russian, German and Austro-Hungarian empires had fallen, and Princess Andrew's uncle Ernest Louis, Grand Duke of Hesse, was deposed.

But after the defeat of the Hellenic Army in the Greco-Turkish War, a Revolutionary Committee under the leadership of Colonels Nikolaos Plastiras and Stylianos Gonatas seized power and forced King Constantine into exile once again.

She was diagnosed with paranoid schizophrenia, first by Thomas Ross, a psychiatrist specialising in the treatment of shell shock, and subsequently by Sir Maurice Craig, who had treated the future King George VI before he had speech therapy.

Both he and Simmel sought advice from Sigmund Freud, who concluded that the delusions derived from sexual frustration and suggested "X-raying her ovaries in order to kill off her libido."

[29] Princess Andrew remained at Kreuzlingen for two years, but after a brief stay at a clinic in Merano in northern Italy, was released and began an itinerant, incognito existence in Central Europe.

[30] In 1937, her daughter Cecilie, her son-in-law Georg, and two of her grandchildren were killed in an air accident at Ostend; she and Prince Andrew met for the first time in six years at the funeral.

[32] During World War II, Princess Andrew was in the difficult situation of having sons-in-law fighting on the German side and a son in the British Royal Navy.

She and her sister-in-law, Princess Nicholas of Greece, lived in Athens for the duration of the war, while most of the Greek royal family remained in exile in South Africa.

She worked for the Red Cross, helped organise soup kitchens for the starving populace and flew to Sweden to bring back medical supplies on the pretext of visiting her sister, Crown Princess Louise.

[37] The occupying forces apparently presumed Princess Andrew was pro-German, as one of her sons-in-law, Prince Christoph of Hesse, was a member of the NSDAP and the Waffen-SS, and another, Berthold, Margrave of Baden, had been invalided out of the German army in 1940 after an injury in France.

[36] After the fall of Italian dictator Benito Mussolini in September 1943, the German Army occupied Athens, where a minority of Greek Jews had sought refuge.

[38] During this period, Princess Andrew hid Jewish widow Rachel Cohen and two of her five children, who sought to evade the Gestapo and deportation to the death camps.

She trained on the Greek island of Tinos, established a home for the order in a hamlet north of Athens, and undertook two tours of the United States in 1950 and 1952 in an effort to raise funds.

[46] In 1960, she visited India at the invitation of Rajkumari Amrit Kaur, who had been impressed by Princess Andrew's interest in Indian religious thought, and for her own spiritual quest.
