This covers the philosophical foundations of American government (the Declaration of Independence) and the structural framework (the U.S. Constitution, its articles, the three branches and how Congress works). These are the building blocks for everything else in an American Government or Civics course, so getting them solid early pays off. If you are coming in cold, start here before moving to amendments or civil liberties.
The Declaration of Independence (1776) laid out the philosophy: government exists to protect natural rights, and its power comes from the people. The Constitution then built the actual machinery, splitting power across three branches (legislative, executive, judicial) and dividing Congress into two chambers with different roles. Understanding this structure is the foundation for everything else in American government.
Natural / unalienable rights
Rights that belong to every person by virtue of being human and cannot be taken away by government. The Declaration names three: Life, Liberty and the pursuit of Happiness.
In simple terms, these are the rights you are born with, not ones the government grants you.
Consent of the governed
The principle that a government's authority comes from the agreement of the people it governs, not from divine right or force.
Think of it as: the people hire the government, and they can fire it if it stops doing its job.
Preamble
The opening statement of the Constitution, beginning "We the People," which sets out the purposes of the federal government (justice, domestic peace, defence, general welfare, liberty).
In simple terms, it is the Constitution's mission statement.
Articles (of the Constitution)
The seven main sections of the Constitution, each covering a major area: the legislature (I), the executive (II), the judiciary (III), state relations (IV), the amendment process (V), the Supremacy Clause (VI) and ratification (VII).
Think of it as: the Constitution's table of contents, where each chapter sets up a different part of the system.
Separation of powers
The division of government authority into three distinct branches (legislative, executive, judicial), each with its own responsibilities, so that no single branch holds all the power.
In simple terms, the framers split the government into three parts on purpose so no one part could become a tyrant.
Bicameral legislature
A legislature made up of two separate chambers. In the U.S., that means the House of Representatives and the Senate, which together form Congress.
Think of it as: two rooms that both have to agree before a law can pass.
Amendments
Formal changes or additions to the Constitution. There are currently 27. The first ten are known collectively as the Bill of Rights.
In simple terms, amendments are the Constitution's update mechanism.
Purpose: justify the colonies' separation from Britain and explain the philosophical basis for independence
Primary author: Thomas Jefferson
Adopted: 4 July 1776
Core philosophy:
Government must protect natural/unalienable rights: Life, Liberty and the pursuit of Happiness
Government power comes from consent of the governed
If government abuses those rights, the people have the right to alter or abolish it
Three main parts:
Statement of rights (the philosophical argument)
List of grievances against King George III
Formal declaration of independence
Preamble: states the purposes of government ("We the People...")
Seven Articles:
Article I: Legislative branch (Congress)
Article II: Executive branch (President)
Article III: Judicial branch (Supreme Court)
Article IV: Relations among states
Article V: Amendment process
Article VI: Supremacy Clause (federal law is the supreme law of the land)
Article VII: Ratification process
27 Amendments have been added since ratification, the first ten being the Bill of Rights
Legislative (Article I): makes the laws. This is Congress, composed of the House of Representatives and the Senate.
Executive (Article II): enforces the laws. Headed by the President.
Judicial (Article III): interprets the laws and determines constitutionality. The highest court is the Supreme Court.
The whole point of splitting power this way is to prevent any one branch from becoming too powerful. Each branch checks the others.
House of Representatives:
2-year terms
Representation based on population (larger states get more seats)
Tax/revenue bills must originate here
Senate:
6-year terms
Equal representation (two senators per state, regardless of size)
Approves treaties and presidential appointments
The compromise between population-based and equal representation was one of the most contentious debates at the Constitutional Convention. It is known as the Great Compromise (or Connecticut Compromise).
Students often think the Declaration of Independence is a law or part of the legal system. It is a philosophical statement justifying independence; the Constitution is the actual legal framework.
Students sometimes confuse the Preamble with a legally enforceable section of the Constitution. The Preamble states goals and purposes but does not grant any specific powers.
The Supremacy Clause (Article VI) means federal law overrides state law when they conflict. Students sometimes think states can simply ignore federal law; they cannot.
Many students mix up which chamber does what. Revenue bills start in the House. Treaty approval sits with the Senate. If you remember "House = people's money, Senate = foreign affairs and appointments," that covers most exam questions.
Know the three unalienable rights by name (Life, Liberty, pursuit of Happiness) and that they come from the Declaration, not the Constitution.
Be able to match each Article (I through VII) to its subject. Articles I, II and III (the three branches) are the ones most frequently tested.
Understand consent of the governed and the people's right to alter or abolish government. Exam questions often phrase this as "What happens if government fails to protect rights?"
House vs. Senate distinctions (term length, basis of representation, unique powers) are a reliable exam topic. Know which chamber handles tax bills and which handles treaties.
The Supremacy Clause is a common short-answer or multiple-choice target. Know where it lives (Article VI) and what it means.
True or false: The Declaration of Independence established the three branches of government.
Answer: False. The Constitution did that. The Declaration laid out the philosophy.
Fill in the blank: Government power comes from the ________ of the governed.
Answer: consent
True or false: The Senate has two representatives per state, regardless of population.
Answer: True.
Fill in the blank: Revenue (tax) bills must originate in the ________.
Answer: House of Representatives
True or false: Article III of the Constitution establishes the executive branch.
Answer: False. Article III establishes the judicial branch. Article II covers the executive.
Q: What are the three unalienable rights named in the Declaration of Independence?
A: Life, Liberty and the pursuit of Happiness.
Q: According to the Declaration, where does government get its power?
A: From the consent of the governed (the people).
Q: What does Article I of the Constitution establish, and what two bodies make up this branch?
A: Article I establishes the legislative branch. It is made up of the House of Representatives and the Senate, which together form Congress.
Q: Name one key difference between the House of Representatives and the Senate in terms of how members are chosen.
A: House members are allocated by population (larger states get more), while every state gets exactly two senators regardless of population.
Q: What is the Supremacy Clause, and in which Article of the Constitution is it found?
A: The Supremacy Clause (Article VI) establishes that the Constitution and federal law are the supreme law of the land, overriding state laws when they conflict.
Q: Which branch of government interprets the laws, and which Article establishes it?
A: The judicial branch, established by Article III. The Supreme Court is its highest court.
This material connects directly to the Bill of Rights and later amendments, which build on the constitutional framework covered here. Understanding Article V (the amendment process) is essential before studying how the Constitution has been changed over time.
The concept of consent of the governed and natural rights also feeds into civil liberties and civil rights topics later in the course. Federalism (the division of power between national and state governments) is a natural next step from the Supremacy Clause discussion.
