After the Independence of Canada, Cascadia and Louisiana, the United Kingdom conserved a great land-locked territory in the midle of North America. Mostly inhabited by several nations of indians who, by 1910 already had very strong modern institutions.
The United Nations were established in 1910 with the conformation of the Nations Assambly. The 15th November 1910, the Union Flag was replaced by the Nations Flag at the Omaha Nations Hall.
In the middle of North America, the United Nations is clearly divided in two regions: the plains in the East and the mountains in the West.
