The main principles of democratic governance include accountability, transparency, participation, and rule of law. Accountability ensures that public officials answer for their actions, while transparency fosters trust in government operations. Participation encourages citizens to engage in the political process, influencing decisions and policies. The rule of law establishes that laws apply universally, ensuring fairness and justice. Together, these principles create a framework that supports the functioning of a healthy democracy, enabling checks on power and fostering a responsive government.
