The difference between a democracy and an autocracy lies primarily in how power is exercised and decisions are made. In a democracy, power rests with the populace through free and fair elections, ensuring that leaders are accountable to the citizens. Policies are determined by majority rule, and there is a strong emphasis on individual rights and liberties. Conversely, in an autocracy, a single ruler or a small group holds absolute power, often circumventing popular participation and restricting freedoms. Decision-making is concentrated, leading to limited public input on governance, which can result in abuses of power and a lack of accountability to the citizenry.
