Common Misconceptions About centurion definition

One common misconception is that every centurion commanded exactly one hundred men. In practice Roman units changed size over centuries, and centurions could command different formations. Another misunderstanding is that centurions were always noble or patrician; many rose through merit and could come from modest backgrounds.

People also mix up centurions with higher Roman officers like legates or tribunes, who had broader strategic roles. Centurions were the hands-on leaders, the ones who ensured formations held together in the mud and blood of battle.
