The Constitution's purpose
The introduction identifies the people as the source of the Constitution and names six goals for the national government.
In Simple, Modern English
We, the people of the United States, establish this Constitution to build a stronger union, create a fair system of justice, keep peace within the country, defend the country together, support the public good, and preserve freedom for ourselves and future generations.
Important Clauses & Details
Popular sovereignty
Government draws its constitutional authority from the people. The opening speaks of one national people rather than listing separate states.
Six goals
Union, justice, domestic peace, common defense, general welfare, and liberty for future generations explain what the framework is meant to accomplish.
Historical Context
The Articles of Confederation had created a loose union with a weak national government. The 1787 Convention proposed a stronger framework. The Preamble explains the purposes of that change and places its authority in the people, rather than a monarch.
The Preamble states purposes; it does not independently grant a branch of government new powers. The original system also excluded many people from political participation.
