Louis XVII, the last Dauphin of France before the title was restored after the French Revolution, never ascended to the throne. In 1793, his parents, King Louis XVI and Queen Marie Antoinette, were executed within a year after the eruption of revolution.
Even before his parents' death, Louis XVII had been held in prison. Two years after their executions, Louis XVII fell ill and died in prison. Similar to the stories that followed Anastasia's death, rumors abound that Louis XVII had not died, but rather escaped.
A DNA investigation carried out in 2000, however, on his remains proved that he had died in captivity as history records.
