The North American Fedration is a union of 11 states in North America (3 constitutional monarchies in personal union and 8 republics), formed on October 9, 1949 (Charter Day). Since its formation, the Federation has been steadily centralized. The Federation was one of the three superpowers during the Cold War. The Federation is considered by many to be the successor of the former United States of America, which made up most of the population (but not area) of the modern Federation.
