Princess Charlotte was the only child of George, the Prince Regent and Caroline, Princess of Wales and grand-daughter of George III. She was thus in direct succession to the throne and, had she lived, would have taken the throne in place of Queen Victoria. In 1816 she married Prince Leopold of Saxe-Coburg and the happy couple were soon expecting an eagerly anticipated child. She tragically died in childbirth on 5 November 1817, prompting a huge outpouring of public grief.
