Key Historical Documents

A handful of founding documents shaped American government, and the test returns to them again and again. Knowing what each one did — and the ideas it introduced — lets you answer questions about the roots of U.S. democracy with confidence.

These key historical documents include the Declaration of Independence, the Constitution, the Bill of Rights, and a few earlier influences. Each added a big idea: natural rights, self-government, limited power, or protected freedoms.

The Declaration of Independence (1776)

The Declaration of Independence, written mainly by Thomas Jefferson, announced that the American colonies were breaking away from Britain. Its most important idea is natural rights — that all people are entitled to “life, liberty, and the pursuit of happiness,” and that governments get their power from the consent of the governed. It is a statement of principles, not a plan of government.

The Constitution and the Bill of Rights

The Constitution (1787) is the actual framework of government — it created the three branches, set up federalism, and established the rule of law. Its first ten amendments, the Bill of Rights (1791), guarantee individual freedoms like speech, religion, and a fair trial. Where the Declaration explains why Americans govern themselves, the Constitution explains how.

Earlier Influences and the Federalist Papers

The founders borrowed ideas from earlier documents. The English Magna Carta (1215) established that even a king must follow the law. The idea of a written agreement to govern together appeared in the Mayflower Compact (1620). And to win support for the new Constitution, supporters wrote the Federalist Papers, essays explaining and defending the design. When the test quotes a document, look for its big idea — natural rights, rule of law, self-government, or protected liberties.

A Routine for Document Questions

1. Declaration of Independence = natural rights + consent of the governed (why we self-govern).
2. Constitution = the framework of government (how we self-govern).
3. Bill of Rights = the first ten amendments protecting individual freedoms.
4. Magna Carta and the Mayflower Compact = earlier roots (rule of law, self-government).
