Napoleon’s only legitimate son, often called Napoleon II or the King of Rome , never ruled France and died young in exile in Austria from tuberculosis at the age of 21.

What Happened to Napoleon’s Son? (Quick Scoop)

Napoleon’s son, born Napoleon François Charles Joseph Bonaparte in 1811, had a life that was more tragic than imperial. He grew up not as a French emperor, but as an Austrian prince, far from the father whose empire had shaped his destiny before he could even walk.

From “King of Rome” to Austrian Prince

• He was born on 20 March 1811 in the Tuileries Palace in Paris to Napoleon and his second wife, Marie Louise of Austria.

• At birth he was given the grand title “King of Rome” and recognized as the Prince Imperial , destined to inherit Napoleon’s empire.

• After Napoleon’s defeat in 1814 and his abdication, Marie Louise took the child to Vienna under the protection of her father, Emperor Francis I of Austria.

• In Austria, his French titles were set aside and he was eventually given the title Duke of Reichstadt and raised as a Habsburg archduke rather than a French heir.

In effect, the boy who was born to rule France was reshaped into a loyal Austrian prince in the very court that had helped bring his father down.

Did He Ever Rule France?

• After Napoleon’s first abdication in 1814, he briefly tried to secure the throne for his son, but the Allies refused.

• During the Hundred Days in 1815, Napoleon again abdicated “in favor of Napoleon II,” but this was never recognized by the victorious powers or by the restored Bourbon monarchy.

• In French history, the son is sometimes counted symbolically as “Napoleon II,” but he never actually governed or exercised power.

So when people ask “what happened to Napoleon’s son?” the striking answer is: he was an emperor only on paper , for a moment, and only in name.

His Short, Sad Life in Vienna

• He grew up at Schönbrunn Palace in Vienna, surrounded by Austrian tutors, speaking German, and largely cut off from French politics.

• His mother, Marie Louise, built a new life in her Italian duchies and in Austria; he saw her, but she was not a constant guiding figure.

• He was intensely aware of his father’s legend and reportedly studied Napoleon’s campaigns and character, trying to model himself on that heroic image.

• Still, he lived under a kind of polite surveillance: too important to ignore, too dangerous (symbolically) to be let loose in European politics.

One biographer summed up his life with a bitter line attributed to him: “My birth and my death – that is my whole story.”

How Did Napoleon’s Son Die?

• He fell ill with a lung disease that modern historians identify as tuberculosis.

• He died on 22 July 1832 , at Schönbrunn Palace, at just 21 years old.

• He never married and had no children , so Napoleon’s legitimate direct line ended with him.

• At the time, his death removed a potential rallying figure for Bonapartist supporters in France, which suited the conservative monarchies of Europe.

In other words, the boy born as the great imperial hope died as a sidelined aristocrat in a foreign court.

What Happened to His Remains?

• After his death, he was originally buried in Vienna.

• Over a century later, during the Second World War, his remains were transferred to Paris and placed at Les Invalides , near Napoleon I’s tomb, to lie symbolically beside the father he barely knew.

This final move turned him, belatedly, back into a figure of French national memory.

Forum & “Trending Topic” Angle

On forums and history discussion boards, **“what happened to Napoleon’s son”** often triggers a few recurring angles:

1. The “What If” Empire Takeover
   People debate what Europe might have looked like if he had survived and tried to claim the French throne in the mid‑19th century. Some imagine a “Napoleon II” reshaping Europe again; others argue the political climate had moved on and he would have remained a symbol more than a real contender.

2. The “Prisoner in Silk” View
   Commenters often describe him as a “political prisoner in all but name,” living in luxury but with no real freedom to choose his destiny, watched carefully by Austrian authorities who feared a Bonapartist revival.

3. Comparisons to Other Royal Heirs
   He is sometimes compared to other tragic heirs—like Louis XVII of France or more modern “shadow monarchs” whose claims exist mostly in theory and in the imagination of supporters.

In modern discussions, he tends to be remembered less as a would‑be emperor and more as a tragic footnote to the Napoleonic story: the son who inherited a name but never a throne.

TL;DR: Napoleon’s son was born to be “Napoleon II” and rule a vast empire, but after his father’s fall he was taken to Austria, turned into the Duke of Reichstadt, never actually ruled France, and died of tuberculosis in Vienna at 21, later being reburied in Paris near his father.
