What is the main purpose outlined in the Preamble of the U.S. Constitution?

The main purpose outlined in the Preamble of the U.S. Constitution is to create a system of fair laws. The Preamble succinctly introduces the guiding principles of the Constitution and expresses the intentions of the framers. It emphasizes the need to form a more perfect union, establish justice, ensure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty for both current and future generations.

The focus on creating a system of fair laws is central to establishing justice and maintaining order within society. This objective underscores the importance of a legal framework that is just and equitable for all citizens, which is a foundational aspect of the U.S. government's purpose.

In contrast, the other options do not represent the primary focus of the Preamble. Establishing a national bank, declaring independence from foreign powers, and formulating trade agreements pertain to specific policies or actions rather than the overarching purpose of the Constitution as articulated in its introduction.
