United Commonwealth of Races
Formed by the Allied Races on the centennial anniversary of the end of the Great War.
Originally the Allied Races agreed to disband the alliance but continue working together to rebuild their world. Though it took time for some races to build trust towards others a majority worked well together.
Eventually the races began to intermingle and begin building mixed communities. This gradual process began to snowball until there was no longer any individual race community but all communities became mixed.
This raised the question of how to manage these communities as the original governmental structure from each race wasn't able to govern all their citizens when they were so far spread. So a new nation was formed where everyone became a citizen.
This new nation was the United Commonwealth of Races, or UCR. This nation took on all the governing methods and cultural aspects of each race and worked to ensure every race was treated equal.
Now over 400 years later this nation still stands strong with the united races working effortlessly to maintain the balance that the nation was founded on.
