What did the U.S. Constitution establish?

The U.S. Constitution primarily established the structure of the U.S. government by outlining the framework for its three branches: the legislative, executive, and judicial branches. This structure was designed to ensure a separation of powers, which helps prevent any one branch from becoming too powerful. Each branch has specific functions and responsibilities, including how laws are made, how they are enforced, and how they are interpreted.

While the Bill of Rights and the rights of citizens are critical aspects of the Constitution, they were introduced later as amendments. The process for amending laws is also included in the Constitution, but the foundational purpose of the document is to create the governmental structure that supports and protects the rights of the citizens it serves.
