Napoléon Bonaparte (15 August 1769 – 5 May 1821) was a Human who lived in the 18th and 19th centuries on Earth. In the aftermath of the French Revolution, he took control of the country as Emperor Napoléon I.
One 23rd century admirer of Bonaparte was the USS Enterprise historian Marla McGivers. Among her possession in her quarters was a painting and a sculpture of his head. Upon seeing the image of Napoleon and similar men from Earth's past, Khan Noonien Singh commented that she must've been drawn to bold men from Earth's past. (TOS episode: "Space Seed")
When Khan and over 80 of his followers disappeared from Earth in the 1990s, that fact had not been recorded in most historical texts. Spock speculated that it was because the governments of Earth did not want to reveal to what he termed as a war weary populace that there was about 80 to 90 Napoléons that were possibly still free.

In the 23rd century, historian Alexander Lazarus created an android replica of Bonaparte on planet Gamma Alpha V, along with many other significant humans from throughout history. (TOS comic: "The Legacy of Lazarus")
Joachim Murat was named a Marshal of France in 1805 by Napoléon Bonaparte. Jean-Luc Picard had an ancestor who once served in Napoleon's army at the Battle of Trafalgar. This ancestor claimed to have beaten Napoleon in a game of chess and that it was months before Napoleon had forgiven him. (TNG novel: The Forgotten War)
