The Separation of Powers is a constitutional principle in the U.S. that divides government responsibilities into three branches: legislative, executive, and judicial. This framework is designed to prevent the concentration of power and ensure a system of checks and balances, where each branch has the ability to limit the powers of the others. The legislative branch makes laws, the executive enforces them, and the judicial interprets them. This separation was established to protect individual liberties and promote accountability, ensuring that no single entity can dominate the political process or infringe upon citizens' rights.
