The North American Alliance was formed in 2970, comprised of much of the area of the former United States and Canada. The Alliance is formed from 90 smaller territories that all send representives that make up the governing body of the alliance. The territories are mostly independant and rely on the Alliance for infrastructure support, and to deal with the other Earth governments as one body.
The formation of the Alliance, along with the European Alliance, marked the end of what is now refered to as the Era of Anarcy. This was the first stable large scale government in 580 years.
