Little is known about the various pre-War countries, aside from countries that have had prominent appearances in the Fallout series such as the United States, and to a smaller extent China, Canada and the Soviet Union. Nonetheless, many nations are mentioned in-game, with most of the information concerning other countries in-game being made prior to the Great War.
