The American Empire, or simply the Imperial America, was a pre-Collapse federal republic and one of the strongest superpowers. The nation was founded by thirteen colonies of Britain in North America. In 1776, the colonies proclaimed their independence over tax disputes and were recognized as the new nation of the United States of America following the Treaty of Paris in 1783. Although a democratic presidential republic for the first half of its history, the United States was placed under a dictatorial government after the Great War and from this point onward was known colloquially as the American Empire. After the Collapse, several governments claimed to be the legitimate successor to the old Empire, but of these claimants the Coalition of Western Republics became the most powerful. The American Empire joined the Axis of Empires to rival Pol America and later the Imperialist Alliance.
