The federal government of the United States is divided into three main branches: the legislative, the executive, and the judicial. The framers of the U.S. Constitution established this structure to ensure a system of shared power, known as federalism, where power is distributed between the national government and the state governments.
Under federalism, each state retains significant independent power, with the national government managing issues that affect the country as a whole. At the national level, the legislative branch, made up of Congress (the Senate and House of Representatives), is responsible for making laws. The executive branch, headed by the President, enforces these laws. And the judicial branch, led by the Supreme Court, interprets the laws. This three-part structure enables a system of checks and balances, where each branch keeps the others from gaining too much power.
- Legislative Branch - Creates laws and has the power to declare war and tax.
- Executive Branch - Enforces and carries out laws; the President also acts as the Commander-in-Chief of the armed forces.
- Judicial Branch - Interprets laws and can declare actions of the other branches unconstitutional.
