The Three Branches
Separation of powers and checks and balances
The people who wrote the Constitution had just escaped a king, and they were terrified of creating a new one. Their solution: never let all the power sit in one place. So they split the federal government into three branches, each with its own job.
- The legislative branch (Congress) makes the laws
- The executive branch (the President) carries out and enforces the laws
- The judicial branch (the courts) interprets the laws and settles disputes about them
Here is a way to keep them straight. Imagine a board game. Congress writes the rulebook. The President runs the game and makes sure everyone plays by the rules. The courts are the referees who decide what a rule actually means when players argue about it.
Splitting power into three piles is called separation of powers. But the founders went further: each branch got tools to block the others, a system called checks and balances.
- The President can veto a bill Congress passes
- Congress can override that veto with enough votes, control the money, and even remove a president through impeachment
- The courts can strike down laws and presidential actions that violate the Constitution
When the test asks what stops one branch of government from becoming too powerful, the answer is checks and balances, or separation of powers.
Know who leads what. The President is in charge of the executive branch. Congress, made up of the Senate and the House of Representatives, makes federal laws. The Supreme Court sits at the top of the judicial branch. Each branch also has its own building in Washington, DC: the Capitol for Congress, the White House for the President, and the Supreme Court building for the justices.
Why does this design matter to you? Because it is slow on purpose. Nothing big happens in American government unless multiple branches agree, which protects against sudden power grabs. When you hear news about a veto, a court striking down a law, or Congress refusing to fund something, you are watching checks and balances work exactly as designed.
