The Southwest Commonwealth was one of the thirteen commonwealths of the pre-War United States. Created in the early 21st century, it was comprised of the former states of Southern California, Nevada and Hawaii.

New CaliforniaEdit

Main article: New California

New California is a region defined by the New California Republic that comprises northern Nevada and all of California. It can be divided into two sections: the Southern California Wasteland and the Nevada Wasteland.

The Nevada Wasteland is described as an empty no man's land in 2161, at least when compared to the Southern California Wasteland.[1]

Mojave WastelandEdit

Main article: Mojave Wasteland

The Mojave Wasteland is a wasteland that comprises southern Nevada and parts of California and Arizona. The Mojave Wasteland is having power struggles between the NCR invaders, Caesar's Legion tribals, and Mr. House. Hoover Dam and the New Vegas Strip are the main interests and concerns. Drug running, gang life, and rampaging tribals are not rare in the area, as well as runaway creatures and hostile wildlife.
