What is the main purpose of the Preamble to the Constitution?

The main purpose of the Preamble to the Constitution is to outline the fundamental purposes and guiding principles of the document. The Preamble serves as an introduction that establishes the foundational goals that the framers intended to achieve through the Constitution. It articulates key concepts such as promoting justice, ensuring domestic tranquility, providing for the common defense, promoting the general welfare, and securing the blessings of liberty to both present and future generations.

This succinct summary sets the tone for the entire Constitution and is essential for understanding the scope and intent of the governance structure that follows. The emphasis on ideals such as liberty and justice reflects the values enshrined in the Constitution and guides how the government should operate and serve the people.

The other options do not accurately capture the essence of the Preamble's purpose: the responsibilities of the branches of government are detailed in the body of the Constitution, amendments relate to changes in law and governance, and the Bill of Rights, which enumerates individual rights, comes after the Preamble and is not its focus.
