14. Julius Caesar
Julius Caesar is famed for his military brilliance and sweeping reforms that transformed Rome’s political and social landscape. However, his relentless pursuit of power and crossing of the Rubicon led directly to the downfall of the Roman Republic. By consolidating authority and declaring himself dictator for life, Caesar set the stage for centuries of imperial rule. As History Extra details, Caesar’s legacy is as much about innovation as it is about the end of a democratic era.
