The concept of separation of powers, checks and balances, and popular sovereignty are fundamental principles in the U.S. government.
Separation of powers refers to dividing the government into three branches: legislative, executive, and judicial, to prevent one branch from becoming too powerful. Checks and balances ensure that each branch has the ability to limit the power of the other branches, maintaining equilibrium. Popular sovereignty means that the power of the government comes directly from the consent of the people.
