Federalism: Federalism is a system where power is divided between a central authority (the federal government) and individual states. This allows for both national unity and local autonomy.
Checks and Balances: Checks and balances refer to the system put in place to prevent any one branch of government from becoming too powerful. Each branch has some control over, or can influence, the actions of other branches.
Separation of Powers: Separation of powers means that governmental power is divided among different branches, each with its own distinct responsibilities. This helps prevent tyranny by ensuring no single branch becomes too dominant.
