United States of America

The United States of America (U.S or USA), commonly known as America, is a country located in North America. It is a federal republic, made up of 35 states, 1 incorporated republic and 3 federal territories. It borders the Canadian Wastes to the north and the Deseret State and Republic of Mexico to the south, while having open access to the Pacific and Atlantic ocean on the west and east. It's capital and largest city is Philadelphia, serving as a federal capital district, with other large cities serving as capitals of states. 
The nation came into existance after the Continental Movement declared open rebellion against the government of the Communist States of America in 1478AD, with Clark Windham forming the Continental Army on March 9th as the main fighting force of the rebellion. After several battles and uprisings in other areas of the nation, the Continental Army scored a decisive victory in the Battle of Cartersville, where Windham ambushed a large contingent of the 6th and 3rd Infantry Division heading to eliminate the rebellion's capital in Richmond. With the fall of the Communist government, Windham and the 6 other leaders of the rebellion established the United States of America, forming the US Congress on 5th of July and writing the constitution on August 9th.
