What was the name of Napoleon’s son who was given the title King of Rome? He was Napoleon II. His full name was Napoleon François Charles Joseph Bonaparte, the only legitimate son of Napoleon I and Marie Louise of Austria.

Born at the Tuileries Palace on 20 March 1811, the child was immediately important to the First French Empire’s succession. Napoleon I granted him the title King of Rome, linking the imperial dynasty to the ancient city and presenting him as heir to Napoleon’s European system.

When Napoleon I abdicated in April 1814, he attempted to pass the French throne to his young son, who was styled Napoleon II. The child never governed France in practice: the Allies restored the Bourbon monarchy, and he was raised in Austria under the title Duke of Reichstadt.

Napoleon II died in Vienna in 1832 at the age of 21. Napoleon III was not this child; he was the son of Louis Bonaparte, Napoleon I’s brother, and became emperor decades later. The title King of Rome therefore points to Napoleon II, even though his imperial reign was only nominal.
