Introduction: Understanding the US Constitution
The United States Constitution is the supreme law of the United States, establishing the framework for the federal government and defining fundamental rights of citizens. Ratified in 1788 and implemented in 1789, it’s the oldest written national constitution still in effect today. The Constitution matters because it serves as the foundation of American democracy, establishing checks and balances between government branches and protecting individual liberties.
Core Constitutional Principles
- Popular Sovereignty: Power ultimately resides with the people
- Federalism: Division of power between national and state governments
- Separation of Powers: Distribution of authority across three branches of government
- Checks and Balances: Each branch limits the powers of the others
- Limited Government: Government authority is restricted by constitutional boundaries
- Individual Rights: Protection of personal liberties against government intrusion
- Rule of Law: No one is above the law, including government officials
