About Ernst August von Hannover (born 1954)
Ernst August von Hannover (German: Ernst August Albert Paul Otto Rupprecht Oskar Berthold Friedrich-Ferdinand Christian-Ludwig Prinz von Hannover Herzog zu Braunschweig und Lüneburg Königlicher Prinz von Großbritannien und Irland, lit. 'Ernest Augustus Albert Paul Otto Rupert Oscar Berthold Frederick-Ferdinand Christian-Louis, Prince of Hanover, Duke of Brunswick and Lüneburg, Royal Prince of Great Britain and Ireland'; born 26 February 1954) is the head of the House of Hanover. As the husband of Princess Caroline of Monaco, he is the brother-in-law of Albert II, Prince of Monaco. == Background and education == Ernst August was born in Hanover, the eldest son of Prince Ernest Augustus of Hanover (1914–1987), the former Hereditary Prince of Brunswick and his first wife, Princess Ortrud of Schleswig-Holstein-Sonderburg-Glücksburg (1925–1980). He was christened Ernst August Albert Paul Otto Rupprecht Oskar Berthold Friedrich-Ferdinand Christian-Ludwig. As the senior male-line descendant of George III of the United Kingdom, Ernst August is head of the House of Hanover. He is a first cousin of Queen Sofía of Spain and King Constantine II of Greece. He left secondary school at the age of 15 to work on a farm, but returned to education later to study at the Royal Agricultural College in England and the University of Guelph in Canada. == Ancestry and heritage == The hereditary Dukedom of Cumberland and Teviotdale and the Earldom of Armagh, borne in 1917 by his paternal great-grandfather, were suspended under the Titles Deprivation Act 1917. However, the title Royal Prince of Great Britain and Ireland had been entered into the family's German passports, together with the German titles, in 1914. After the German Revolution of 1918–19, with the abolition of the privileges of nobility, such titles survived only as part of the legal surname.
