What is the primary function of the U.S. Constitution?

The primary function of the U.S. Constitution is to serve as a rule book for governing the nation. This foundational document establishes the framework for the federal government, delineates the separation of powers among the legislative, executive, and judicial branches, and outlines the rights of the citizens. By defining the structure and powers of government, as well as protecting individual liberties, the Constitution ensures that the country operates within a system of laws rather than arbitrary rule.

While the Constitution does have historical significance, its main purpose goes beyond just being a historical document. It is not primarily aimed at providing guidance specifically to the military, nor is it mainly focused on international treaties, which are governed by additional laws and protocols. Instead, it lays the groundwork for governance and the relationship between the government and its citizens, making it the cornerstone of American democracy.
