Three Branches: The Backbone of U.S. Government
The U.S. government is divided into three main branches:
- Legislative Branch
- Executive Branch
- Judicial Branch
This system is designed to make sure no single person or group becomes too powerful. It’s called “separation of powers.”
Each branch has its own role, powers, and responsibilities. Let’s take a closer look.
1. The Legislative Branch – Makes the Laws
The Legislative Branch is also known as Congress. It is made up of two parts:
- The Senate
- The House of Representatives
Together, these two chambers are responsible for making federal laws.
The Senate
- There are 100 Senators (2 from each state).
- Senators serve six-year terms.
- They approve treaties and confirm federal officials like judges and cabinet members.
The House of Representatives
- There are 435 members.
- Number of Representatives per state is based on population.
- They serve two-year terms.
- They handle tax laws and budget issues.
Congress can also declare war, impeach the President, and override a veto with enough votes.

Supreme Court Details
- Made up of 9 Justices (including the Chief Justice).
- Justices are appointed for life by the President and confirmed by the Senate.
- The Court decides if laws are constitutional.

Checks and Balances: Keeping Power in Check
Each branch of government has powers that check the other branches. This system is designed to prevent abuse of power.
Examples of Checks and Balances
- Congress can pass laws, but the President can veto them.
- The Supreme Court can rule a law unconstitutional.
- The President can appoint judges, but Senate must confirm them.
This creates a balance where no branch becomes too strong.

The Role of the Constitution
The U.S. Constitution is the foundation of the government. Written in 1787, it outlines the structure, powers, and rules of the government.
Key Features of the Constitution:
- Seven Articles explain the branches and powers.
- 27 Amendments, including the Bill of Rights, protect individual freedoms.
It is known as a “living document”, meaning it can be changed through amendments.

Federal vs. State Government
The U.S. has a federal system, meaning power is shared between the national government and state governments.
- The Federal Government handles issues like defense, immigration, and trade.
- State Governments manage education, public safety, and transportation within their borders.
Each state has its own constitution, governor, legislature, and courts.
