What is the purpose of the Constitution’s preamble?

The purpose of the Constitution’s preamble is to state the purposes and guiding principles of the document. The preamble serves as an introduction to the Constitution, articulating the intent behind its creation and outlining the fundamental goals of the government it establishes. It begins with the famous phrase "We the People," emphasizing the democratic foundation of the government and its authority derived from the citizens. By listing key objectives like establishing justice, promoting the general welfare, and securing liberty, the preamble effectively sets the stage for the detailed articles that follow, which elaborate on the structure, powers, and limits of government.

The preamble does not specify amendments, define powers of government branches, or list individual rights directly; these elements are addressed in the articles and subsequent amendments of the Constitution. Instead, the preamble encapsulates the overarching spirit and philosophy intended to guide the functioning of the entire constitutional framework.
