A "tyrant" is a ruler who exercises power in a cruel or oppressive manner. This term often refers to leaders who disregard laws and govern without the consent of the people. Tyrants may use fear, violence, and propaganda to maintain control over their subjects. Historically, many figures have been labeled as tyrants, such as Julius Caesar in ancient Rome or Adolf Hitler during World War II. These leaders often prioritize their own interests over the well-being of their citizens, leading to widespread suffering and injustice. The concept of tyranny is often discussed in political philosophy and ethics.
