The significance of the separation of powers in a democratic government lies in its role in preventing the concentration of authority and fostering checks and balances within the political system. By dividing government responsibilities among the legislative, executive, and judicial branches, each branch operates independently while holding the others accountable. This framework encourages cooperation and protects against abuses of power by ensuring that no single branch can dominate governance. The separation of powers helps safeguard individual rights, promotes stability, and reinforces democratic principles, essential for a functioning and resilient political system.
