US States

A 50-unit decentralized governance framework operating under a federal constitutional republic.

The United States utilizes a dual-sovereignty model to manage 50 distinct jurisdictions. Each state maintains its own constitution, legislature, and judicial system: ranging from California (the largest economy) to Rhode Island (the smallest landmass). This system delegates specific powers (education and local policing) to the states while reserving federal authority for national defense and interstate commerce. The Tenth Amendment serves as the legal backbone for this distribution. This structure allows for regional policy experimentation (laboratories of democracy) across 3.8 million square miles.
