Democracies are systems of government where power is vested in the people, who exercise that power directly or through elected representatives. This form of governance promotes participation, equality, and the protection of individual rights, allowing citizens to have a say in decision-making processes. In a democracy, elections are held regularly to choose leaders and determine policies. The principles of freedom, equality, and justice are fundamental, ensuring that all voices are heard. Various types of democracies exist, including direct and representative democracies, each with its own mechanisms for citizen involvement and governance.
