The United States of America, more commonly known as the USA, the US, the United States, and America, is a country located between Canada and Mexico on the North American Continent. It is a federal constitutional republic with Hannah Charlottenburg as its President. The United States is a melting pot of ideas, cultures, and ways of life, with citizens being able to trace their ancestry from England to Russia to India to China and far more places around the globe. 
Following the destruction of its capital and upper government during the Washington Catastrophe, America's de-jure capital is the re-built city of Washington-Alexandria, and it's de-facto capital is Philadelphia. America's national mage agency is the USDMA/DMA, whose commander-general is currently Afton Hex. 
The United States is a leading figure on the world stage, being one of the four corners of the 2100 world order. It heads the Pact of Liberty, and works with its close ally the EU in the NATO/NHC space colony program. Throughout much of the first 100 years of the second millennium, America ruled the Pax Americana as Earth's sole superpower, though following the collapse of Communist China and the end of global autocracy, America relaxed many of its policies. It re-organized the North Atlantic Treaty Organization into the New Horizon Colonies, and started focusing on its own myriad of internal problems. Despite this, many will argue that the world still exists within the Pax Americana, given that the American ideals of freedom, liberty, and democracy were ultimately achieved.
