Ernest Augustus, Duke of Brunswick
Ernest Augustus (Ernest Augustus Christian George, German: Ernst August Christian Georg); 17 November 1887 – 30 January 1953) was Duke of Brunswick from 2 November 1913 to 8 November 1918. He was a grandson of George V of Hanover, thus a Prince of Hanover and a Prince of the United Kingdom. He was also a maternal grandson of Christian IX of Denmark and the son-in-law of German Emperor Wilhelm II. The Prussians had deposed King George from the Hanoverian throne in 1866, but his marriage ended the decades-long feud between the Prussians and the Hanoverians.

Early life

Ernest Augustus was born at Penzing near Vienna, the sixth and youngest child of former Crown Prince Ernest Augustus of Hanover and his wife, Princess Thyra of Denmark. His great-grandfather, Prince Ernest Augustus, Duke of Cumberland, the fifth son of George III of the United Kingdom, became king of Hanover in 1837 because Salic Law barred Victoria, Queen of the United Kingdom, from inheriting the Hanoverian throne.

His father succeeded as pretender to the Hanoverian throne and as Duke of Cumberland and Teviotdale in the peerage of Great Britain in 1878. The younger Ernest Augustus became heir apparent to the dukedom of Cumberland and to the Hanoverian claim upon the deaths of his two elder brothers, George and Christian. Through his mother, he was a first cousin of Christian X of Denmark, Haakon VII of Norway, George V of the United Kingdom, Constantine I of Greece and Nicholas II of Russia.

In 1884, the reigning Duke of Brunswick, a distant cousin, died.  Since the younger branch of the House of Guelph ended with him, under house rules it would have passed to the Duke of Cumberland, who immediately claimed the throne.  However, the Imperial Chancellor, Otto von Bismarck, managed to get the Federal Council (Bundesrat) of the German Empire to rule that the Duke of Cumberland would disturb the peace of the empire if he ascended the throne of Brunswick.  Bismarck did this because the duke had never formally renounced his claims to the kingdom of Hanover, which had been annexed to Prussia in 1866 following the end of the Austro-Prussian War (Hanover had sided with losing Austria). Instead, Prince Albrecht of Prussia became the regent of Brunswick.  After Prince Albrecht's death in 1906, the duke offered that he and his elder son, Prince George, would renounce their claims to the Duchy of Brunswick in order to allow Ernest Augustus, his only other surviving son, to take possession of the Duchy, but this option was rejected by the Bundesrat and the regency continued, this time under Duke Johann Albrecht of Mecklenburg-Schwerin, who had previously acted as regent for his nephew in Mecklenburg.

Marriage and accession to the duchy of Brunswick

When Ernest Augustus's older brother George died in an automobile accident on 20 May 1912, the German Emperor, Wilhelm II, sent a message of condolence to the Duke of Cumberland. In response to this friendly gesture, the Duke sent his only surviving son, Ernest Augustus, to Berlin to thank the Emperor for his message. Ernest Augustus and Wilhelm II were third cousins through George III of the United Kingdom. In Berlin, Ernest Augustus met and fell in love with the emperor's only daughter, Princess Victoria Louise of Prussia.

On 24 May 1913, Ernest Augustus and Victoria Louise, third cousins once removed through descent from George III's sons King Ernest Augustus of Hanover and Edward, Duke of Kent, were married to each other.  This marriage ended the decades-long rift between the Houses of Hohenzollern and Hanover. The wedding of Prince Ernest Augustus and Princess Victoria Louise was also the last great gathering of European sovereigns before the outbreak of the Great War. In addition to the German Emperor and Empress and the Duke and Duchess of Cumberland, King George V and Queen Mary of the United Kingdom and Tsar Nicholas II attended. Upon the announcement of his betrothal to Princess Victoria Louise in February 1913, Ernest Augustus swore allegiance to the German Empire and accepted a commission as a cavalry captain and company commander in the Zieten–Hussars, a Prussian Army regiment in which his grandfather (George V) and great-grandfather (Ernest Augustus) had been colonels. Two imprisoned British spies, Captain Stewart and Captain Trench, were pardoned and released by the German Emperor as a wedding present to the United Kingdom. George V of the United Kingdom had given consent to the marriage on 17 March 1913, as required by the Royal Marriages Act.

On 27 October 1913, the Duke of Cumberland formally renounced his claims to the duchy of Brunswick in favor of his surviving son. The following day, the Federal Council voted to allow Ernest Augustus to become the reigning Duke of Brunswick. The new Duke of Brunswick formally took possession of his duchy on 1 November.  He received a promotion to colonel in the Prussian Zieten Hussars. The new duke and duchess of Brunswick moved into Brunswick Palace in the capital of Brunswick and began their family with the birth of their eldest son, Prince Ernest Augustus, less than a year after their wedding.

During the First World War, Ernest Augustus rose to the rank of major-general.

Abdication and later life
In 1917, the British dukedom of Ernest Augustus's father, and his own title as a Prince of the United Kingdom of Great Britain and Ireland, were suspended by the Titles Deprivation Act 1917, which took effect in 1919, as a result of the Duke's service in the German army during the war.  On 8 November 1918, Ernest Augustus was forced to abdicate his throne, as were all the other German kings, grand dukes, dukes, and princes during the German Revolution of 1918–1919.<ref>{{cite web |date=28 March 1919 |title=At the Court at Buckingham Palace, the 28th day of March, 1919. |url=http://www.london-gazette.co.uk/issues/31255/pages/4000 |access-date=28 November 2011 |work=London Gazette |publisher=His Majesty's Stationery Office |pages=Issue 31255, Page 4000 |quote= Their Lordships do humbly report to Your Majesty that the persons hereinafter named have adhered to Your Majesty's enemies during the present war: —His Royal Highness Leopold Charles, Duke of Albany, Earl of Clarence and Baron Arklow; His Royal Highness Ernest Augustus, Duke of Cumberland and Teviotdale, Earl of Armagh; His Royal Highness Ernest Augustus (Duke of Brunswick), Prince of Great Britain and Ireland; Henry, Viscount Taaffe of Corren and Baron of Ballymote."}}</ref> Thus, when his father died in 1923, Ernest Augustus did not succeed to his father's title of Duke of Cumberland.  For the next thirty years, Ernest Augustus remained as head of the House of Hanover, living in retirement on his various estates, mainly Blankenburg Castle in Germany and Cumberland Castle in Gmunden, Austria.  He also owned Marienburg Castle near Hanover, although rarely ever living there until 1945.

While Ernest Augustus never officially joined the Nazi Party, he donated funds and was close to several leaders.  As a former British prince, Ernest Augustus, as well as Victoria Louise, desired a rapprochement between the United Kingdom and Germany.  Ostensibly desiring to pursue an alliance with the UK, in the mid-1930s, Adolf Hitler took advantage of their sentiment by asking the couple to arrange a match between their daughter Princess Frederica and the Prince of Wales. The Duke and Duchess of Brunswick refused, believing that the age difference was too great.  After his abdication in 1936, Edward VIII and his wife visited "the Cumberlands" at Cumberland Castle in Gmunden, Austria. In 1938 Princess Frederica married Prince Paul of Greece, brother and heir-presumptive of King George II of Greece.

By the time the Second World War ended in Europe in April 1945, he and his family were staying at Blankenburg.  A few days before Blankenburg was handed over to the Red Army by British and U.S. forces in late 1945, to become part of East Germany, the family was able to move to Marienburg Castle, at the time located in the British Occupation Zone, with all their furniture, transported by British Army trucks, on the order of .

He lived to see one of his children become a consort to a monarch – in 1947 his daughter Frederica became Queen of the Hellenes when her husband Prince Paul of Greece and Denmark succeeded his brother as King.  The Duke of Brunswick is also the maternal grandfather of Queen Sophia of Spain and the former King Constantine II of Greece.

Ernest Augustus died at Marienburg Castle in 1953.  He was interred, later to be joined by the remains of his wife, in front of the Royal Mausoleum in the Berggarten at Herrenhausen Gardens in Hanover, which is the burial chapel of King Ernest Augustus of Hanover and his wife.  After the destruction of the former Leine Palace during the Second World War, the remains of the Duke's ancestors King George I of Great Britain and his parents were also moved to the mausoleum.
