The Constitution was the most important law made up by Mexicans Its rules and regulations tell Mexicans how to behave, how to live together, and how to find solutions to our problems. It also should be the way the Government functions.

The government is a representative government because the people elect other people to represent the public. It is democratic because the citizens participate in electing the ruler.

Article 49 of the Constitution divides the government into three branches:
1.The Legislative
2. The Executive,
3. The Judicial System

• The Legislative Branch makes the laws, discussing the country's problems and overseeing the actions of the other branches.  The Legislative Branch is also called the Congress of the Union. It is made up of 500 Representatives and 128 Senators.
  
• The Executive branch is where the President comes into play.  The President is in charge of the Army, the Navy and the Air Force. He can declare war on other countries, but to do so he needs the authorization of Congress. Department of Health, Department of Labour and the Department of Tourism are examples of departments in the executive branch.  
• The Judicial System is in charge of seeing that the Constitutional laws are enforced.
