A dictator is a leader who rules a country with complete power and refuses to share it or give it up. Unlike presidents or prime ministers in democracies who must follow laws, answer to voters, and leave office when their term ends, a dictator makes all the decisions alone and often uses force to stay in control.

Dictators typically rise to power during times of crisis or upheaval, sometimes by overthrowing an existing government through military force (called a coup), and sometimes by gradually dismantling democratic systems after being elected. Once in power, they eliminate opposition by shutting down newspapers that criticize them, jailing political opponents, and rigging elections or canceling them entirely.

History's dictators include figures like Adolf Hitler in Nazi Germany, Joseph Stalin in the Soviet Union, and Saddam Hussein in Iraq. These leaders caused tremendous suffering, starting wars, persecuting innocent people, and destroying their countries' freedoms. Modern dictators like Kim Jong Un in North Korea maintain power through propaganda, secret police, and controlling what citizens can see, say, or do.

In everyday conversation, people sometimes use dictator playfully to describe someone acting too bossy, like a friend who insists on controlling every detail of a group project.
