United States of America

The United States of America (USA or U.S.), commonly referred to as the United States or America, is a federal republic composed of 22 states, a federal district, several territories, and various possessions. At 2.35 million square miles (6.08 million km2), the Confederate States is the world's seventh-largest country by total area. The capital is Washington D.C., and the largest city by population is New York City.

The United States emerged from the thirteen British colonies established along the East Coast of the North American continent. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, and the subsequent Declaration of Independence in 1776. The war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties. The United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, and gradually admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the War for Southern Independence led to the abolition of slavery and the loss of the Southern states, which formed the Confederate States of America.

Despite the loss of the Confederacy, by the end of the 19th century, the United States had begun to extend its influence across the Western Hemisphere, and its economy, driven in large part by the Industrial Revolution, began to soar; though the consistent rivalry with their southern cousins would continue to dominate both domestic and foreign policy in the country, especially following the formation of the Confederacy of American Syndicates in 1917.
