Democracy is a system of government in which power is vested in the people, who exercise it directly or through elected representatives. It is characterized by the principles of political equality, majority rule, and protection of individual rights and freedoms. In a democratic society, citizens have the right to participate in decision-making processes, such as voting in elections, expressing their opinions, and holding their government accountable. Democracy also typically includes the rule of law, respect for human rights, and a separation of powers among different branches of government.
