United States of America

The United States of America, colloquially referred to as the United States, U.S., or simply America, was a pre-War federal republic, and one of the only two known nuclear superpowers remaining by the end of the Resource Wars in 2077. By that point, the U.S.A. had around 400 million citizens, with a political system increasingly controlled by a military-corporate oligarchy with access to nuclear, biological, and chemical weapons, nuclear fusion and fission technology, orbital facilities, and other advanced technologies it had pioneered.

The United States ceased to exist during and after the eleven year long Sino-American War came to a close, when it and the People's Republic of China unleashed their nuclear arsenals upon each other. As the American government controlled by the military-corporate oligarchs abandoned the country shortly before the nuclear exchanges began, there was no command and control structure remaining that could organize any recovery efforts, leading to the total or near collapse of society, economy, and its military.

Survivors went on to organize themselves on their own, creating new tribes, states, and other recognizable organizations. The largest and arguably most important of these, became known as the New California Republic, a sovereign democratic state with hundreds of thousands of citizens, a standing army, and the largest known economy in the post-nuclear world. Other notable states include the totalitarian Caesar's Legion, a militaristic autocracy, and the Enclave, a collection of minuscule nation states scattered across North America, claiming to be the legal continuation of the United States.
