The U.S. government is built on a foundation of federalism, separation of powers, and checks and balances. These principles divide power between national and state governments, and among three branches of the federal government, to prevent any single entity from becoming too powerful. The Constitution outlines the structure and powers of the government, including enumerated, reserved, and concurrent powers. It also establishes the legislative, executive, and judicial branches, each with specific responsibilities and the ability to limit the others' authority through various mechanisms.
