There are three branches of government. Why?

Answers from the USCIS list

Give one of these answers.

• So one part does not become too powerful
• Checks and balances
• Separation of powers

Our explanation

The Founders feared one person or group could get too much power. So they separated power into three branches. This is called separation of powers. Each branch can check, or limit, the others.

Remember it

3 branches share power, so no 1 part becomes too powerful.
