Prince Ernest Augustus of Hanover (born 1914)

He ceased being heir to the duchy of Brunswick at the age of four, when his father abdicated in 1918. After his father's death in 1953, he became head of the House of Hanover. During World War II, he fought at the Russian Front as Oberleutnant in the staff of Generaloberst Erich Hoepner. He was seriously injured near Kharkiv in spring 1943. After the 20 July plot in 1944, he was imprisoned for a few weeks by the Gestapo in Berlin. He had joined the SS in 1933 and remained a member for one year. His official "denazification" certificate from 1949 vetting his Third Reich associations classified him as "a nominal Nazi supporter", Duke of Cumberland and Teviotdale, Earl of Armagh, which however were all suspended under the Titles Deprivation Act 1917. In addition to being a German, he also held British nationality, after successfully claiming it under the Sophia Naturalization Act 1705 in the case of Attorney-General v. Prince Ernest Augustus of Hanover. Nonetheless, a problem arose as foreign royal titles cannot be entered into a British passport. Therefore, the titles Prince of Hanover, Duke of Brunswick and Lüneburg could not be mentioned there, nor could the British titles due to the Titles Deprivation Act 1917. The name which was finally entered into his British documents, was thus Ernest Augustus Guelph, with the addition of His Royal Highness. Guelph is thus also the British last name of his siblings and children, all styled Royal Highnesses in the United Kingdom. In 1961 he sold his remaining properties at Herrenhausen Gardens, including the site of Herrenhausen Palace which had been destroyed by a British bombing raid in 1943. He kept however the Princely House, a small palace built in 1720 by George I of Great Britain for his daughter Anna Louise. Ernest Augustus converted Marienburg Castle into a museum in 1954, after having moved to nearby Calenberg Demesne, which caused a row with his mother, who was forced to move out. He also sold the family's exile seat, Cumberland Castle at Gmunden, Austria, to the state of Upper Austria in 1979, but his family foundation based in Liechtenstein kept vast forests, a game park, a hunting lodge, ''The Queen's Villa'' and other property at Gmunden. The family property is now managed by his grandson Ernst August. ==Marriage and children==

In 1941 during the Second World War, his cousin Prince Hubertus of Prussia married the noted society beauty and aristocrat Baroness Maria Anna von Humboldt-Dachroeden (1916–2003). The couple, however, divorced in 1943, after her affair with Ernest Augustus resulted in the birth of a son. Ernest Augustus however did not marry Maria Anna because his parents would not have approved, since she was considered of inadequate birth and was also a divorcée, and the marriage would have made his younger brother Prince George William heir to the headship of the House of Hanover. The child, christened Christian Ernst August Hubertus, Freiherr von Humboldt-Dachroeden, was born in 1943 and is currently a bank consultant. On 5 September 1951, Ernest Augustus married Princess Ortrud of Schleswig-Holstein-Sonderburg-Glücksburg (1925–1980). The wedding was attended by many important royal figures, including his sister Queen Frederica and her husband King Paul of Greece, and the heads of the houses of Saxony, Hesse, Mecklenburg, Oldenburg, and Baden. The wedding was followed with a reception in the Gallery Building at Herrenhausen Gardens, the only part of the House of Hanover's former summer palace still intact, as the palace itself had been burned down during World War II. His children by his first wife are: • Princess Marie of Hanover (born 26 November 1952), married Count Michael Georg von Hochberg-Fürstenstein (b. 1943) and had issue. • Prince Ernst August of Hanover (born 1954), married firstly Chantal Hochuli (b. 1955) and had issue, married secondly Princess Caroline of Monaco and had issue. • Prince Ludwig Rudolf of Hanover (1955–1988), married Countess Isabelle von Thurn und Valsássina-Como-Vercelli (1962–1988), with whom he had one son. Ludwig died of suicide shortly after discovering the body of his wife, who had died of a drug overdose. • Princess Olga of Hanover (born 17 February 1958) • Princess Alexandra of Hanover (born 18 February 1959), married Andreas, 8th Prince of Leiningen (b. 1955) and had issue. • Prince Heinrich of Hanover (born 1961), married Thyra Donata Sixtina von Westernhagen and had issue. In 1954, the couple, together with Ernest Augustus's three younger brothers, took part in the ship tour organized by his sister, Queen Frederica, and her husband King Paul of Greece, which became known as the "Cruise of the Kings" and was attended by over 100 royals from all over Europe. Princess Ortrud died in 1980. Ernest Augustus married again in 1981, Countess Monika zu Solms-Laubach (1929–2015), daughter of Georg, 9th Count of Solms-Laubach (1899–1969) and his wife, Princess Johanna of Solms-Hohensolms-Lich (1905–1982). He died at Schulenburg, Pattensen, Lower Saxony, Germany, aged 73, and was buried next to his first wife on a round bastion of Marienburg Castle (Hanover). ==In popular culture==
