What was the IQ of Napoleon?

Written by Editorial Team | Last Updated: August 2026

Precise numerical intelligence quotient evaluations did not exist during the lifetime of Napoleon Bonaparte, as modern psychometric testing and standardized IQ scales were developed over a century after his death. Consequently, any specific numerical IQ score frequently cited in popular culture or biographical anecdotes—often claimed to be around 145—is a modern retroactive estimate based purely on subjective interpretations of his brilliant military campaigns, prolific administrative reforms, and complex legal codifications. Historians note that while his strategic genius and organizational capacity were undeniably extraordinary, assigning a modern clinical IQ score is entirely unscientific.
