Princess Margarita of Greece and Denmark (Μαργαρίτα; 18 April 1905 – 24 April 1981) was by birth a Greek and Danish princess as well as Princess of Hohenlohe-Langenburg by marriage. An elder sister of Prince Philip, Duke of Edinburgh (husband of Queen Elizabeth II), she was, for a time, linked to the Nazi regime. The eldest daughter of Prince Andrew of Greece and Denmark and Princess Alice of Battenberg, Margarita spent a happy childhood between Athens and Corfu. In her youth, however, she witnessed the Balkan Wars (1912–1913), followed by the First World War (1914–1918) and the Greco-Turkish War (1919–1922). For the young princess and her relatives, these conflicts had dramatic consequences and led to their exile in Switzerland (between 1917 and 1920), then in France and the United Kingdom (from 1922 to 1936). During their exile, Margarita and her family depended on the generosity of their foreign relatives, in particular Princess George of Greece and Denmark (who offered them accommodation in Saint-Cloud) and Lady Louis Mountbatten (who supported them financially). At the end of the 1920s, Margarita's mother was struck by a mental health crisis which led to her confinement in a Swiss psychiatric hospital. Shortly after, in 1931, Margarita married Prince Gottfried of Hohenlohe-Langenburg. The couple then moved to Weikersheim Castle, where they raised a family made up of four sons (Princes Kraft, Georg Andreas, Rupprecht and Albrecht) and a daughter (Princess Beatrix). Members of the Nazi party from 1937, Gottfried and Margarita used their family connections to promote a rapprochement of Nazism within the United Kingdom, though without success. During the 1930s, the couple also made several trips abroad. In particular, she visited New York in 1934 to testify in favor of Gloria Morgan Vanderbilt, Gottfried's former fiancée, in the case between her and her in-laws for the custody of her daughter, also named Gloria. Affected by the Second World War, which divided her relatives into two factions, Margarita spent time in Langenburg during the conflict.
