Which part of the Constitution discusses the formation of a more perfect union?

The Preamble of the Constitution articulates the foundational goals and purposes that underlie the Constitution itself. One of the key phrases within the Preamble is the commitment to "form a more perfect union." This phrase conveys the intention behind the Constitution to create a stronger and more cohesive nation, improving upon the previous governmental framework established by the Articles of Confederation. The Preamble sets the stage for the entire document by outlining the aspirations of the framers, including promoting justice, ensuring domestic tranquility, and securing the blessings of liberty for future generations.

In contrast, the Bill of Rights primarily focuses on enumerating specific individual rights and protections. The Articles lay out the structure and function of the government itself rather than the philosophical goals of the Constitution. The Amendments refer to changes made to the original document, which do not encompass the overarching objectives stated in the Preamble.
