Prince Charles Edward was Queen Victoria’s favourite grandson. In 1900, the sixteen-year-old Prince was the only viable British contender for the hugely wealthy Dukedom of Saxe Coburg and Gotha in Germany. Ordered to go by Queen Victoria, he took the title and was transformed from a British Prince into a German Duke – Herzog Carl Eduard. The course of his life was altered in ways neither he nor Queen Victoria could have ever imagined. At the outbreak of the First World War, Prince Charles Edward had no option but to fight for Germany against the country of his birth. When the War ended, he was stripped of his British titles, and an Act of Parliament branded him a Traitor Peer. Disillusioned and depressed, Charles Edward became an enthusiastic supporter of Adolf Hitler’s National Socialist Workers’ Party, and unwittingly helped him in his rise to power. Including exclusive first ever interviews with Charles Edward’s direct descendants, this documentary tells the tragic story of the young English Prince who became a forgotten footnote in the Royal Family’s history.
