The United States of the New Continent (USN) is a supranational union of the North and South American countries. The USN capital, where the USN Central Government operates, is Washington DC. The union's roots date back to 2011, when its relations with Australia began to sour following a diplomatic incident over the detention of an Australian ship named "The Trinidad". The United States and Canada begin negotiations on merging with South American countries after the Republic of Zaftra is formed in 2015. These talks culminate in the creation of the USN five years later.
