The basic principles found in the U.S. Constitution include:

1. Popular sovereignty: The authority of the government is derived from the consent of the people, and they have the ultimate power to govern themselves.

2. Limited government: The powers of the government are restricted and specified in the Constitution to prevent it from becoming too powerful and infringing upon individual rights.

3. Separation of powers: The government is divided into three branches – the legislative, executive, and judicial – to ensure a system of checks and balances, preventing any one branch from becoming too dominant.

4. Federalism: The division of power between the central government and state governments, with each having their own areas of authority and responsibilities.

5. Republicanism: The United States is a republic, where citizens elect representatives to make decisions on their behalf, rather than having a direct democracy.

6. Individual rights: The Constitution protects fundamental rights and freedoms of individuals, including freedom of speech, religion, and due process.

7. Rule of law: The principle that all individuals, including those in positions of power, are subject to the law and no one is above it.

8. Judicial review: The power of the courts to review and interpret laws and determine their constitutionality.

9. Amendments: The Constitution can be amended or changed through a specific process outlined in Article V, allowing for the document to adapt to changing times and circumstances.

10. Supremacy of the Constitution: The Constitution is the supreme law of the land and takes precedence over any other laws or government actions.

1. Popular Sovereignty: This principle states that the power of the government comes from the people. The Constitution establishes that the authority of the government is derived from the consent of the governed.

2. Limited Government: The Constitution sets limits on the powers of the government to prevent it from becoming too powerful. It establishes a system of checks and balances, dividing power between the three branches of government: the legislative, executive, and judicial branches.

3. Separation of Powers: The Constitution divides the powers of the government among the three branches, with each branch having its own distinct responsibilities and functions. This separation of powers ensures that no single branch has too much power and helps prevent the abuse of power.

4. Federalism: The Constitution establishes a federal system of government, where power is divided between the central government and the states. This allows for a balance of power and allows states to have some autonomy in governing their own affairs.

5. Republicanism: The Constitution establishes a republican form of government, where the people elect representatives to make decisions on their behalf. This system ensures that the government is accountable to the people and reflects their will.

6. Individual Rights: The Constitution protects individual rights and freedoms by incorporating the Bill of Rights, which guarantees specific liberties, such as freedom of speech, religion, and assembly. These rights are protected from government infringement.

7. Rule of Law: The Constitution establishes the rule of law, which means that everyone, including the government, is subject to and must abide by the law. The Constitution is the supreme law of the land and provides the framework for the legal system in the United States.
