Key features of a democratic system include free and fair elections, the rule of law, separation of powers, protection of human rights, and active civic participation. Free and fair elections allow citizens to choose their representatives and hold them accountable. The rule of law ensures that laws apply equally to all individuals, preventing abuse of power. Separation of powers divides government responsibilities among different branches to prevent any one branch from becoming too powerful. Protection of human rights guarantees fundamental freedoms, such as freedom of speech and assembly. Lastly, active civic participation encourages citizens to engage in political processes, fostering a vibrant democracy.
