What is "napoléon charles bonaparte?

Napoléon Charles Bonaparte (October 10, 1802 – May 5, 1807) was the eldest son of Louis Bonaparte, the King of Holland, and Hortense de Beauharnais, stepdaughter of Napoleon I. He was a nephew of Napoleon I.

He was briefly seen as a potential heir to the French Empire. Napoleon I initially had no direct heir, and there was some hope that he might adopt Napoléon Charles. His early death at the age of four from croup was a significant blow to the Bonaparte family. Had he lived, the succession of the French Empire might have looked very different. His younger brother, Napoléon-Louis Bonaparte later became Napoleon III, the Emperor of the French.
