The world of Wings of Freedom is mainly divided amongst three international superpowers: the Holy Brritannian Empire, the Chinese Empire, and the European Union. Australia has remained independent, and is not a major player in international politics, instead becoming a neutral state akin to real-world Switzerland. The Middle Eastern Federation is not a supernation, however, it is believed to have warm relationships with the E.U. and also being fairly democratic. The MEF is conquered quite quickly by Britannia and renamed Area 18.
Much of the series is set in Japan. On August 10, 2010 a.t.b., the Holy Empire of Britannia overpowered Japanese forces and conquered the country with their newly-developed robotic weapons, the Knightmare Frames, in less than a month. Japan lost its freedom, its rights, and even its name, becoming "Area 11" and its people "Elevens". The Elevens are forced to survive in ghettos while Britannians live in first-class settlements. Rebel elements persist, however, as pockets of Japanese resistance struggle against the Empire for the independence of Japan, partly due to Japan surrendering before all of its human resources would have been depleted in the struggle against the Britannian invasion.After his father, Emperor Charles zi Britannia, did nothing to pursue the terrorists who murdered his mother and crippled his sister, Lelouch vi Britannia vowed to destroy Britannia after being banished from his home.
