On July 4, 1776, as the colonies were fighting Great Britain in the American Revolutionary War, delegates from the 13 colonies unanimously issued the Declaration of Independence. The war ended in 1783 with the recognition of independence of the United States from the Kingdom of Great Britain, and was the first successful war of independence against a European colonial empire.Greene, Jack P.; Pole, J.R., eds. (2008). A Companion to the American Revolution. pp. 352–361. The country’s constitution was adopted on September 17, 1787 and ratified by the states in 1788.

This involved displacing American Indian tribes, acquiring new territories, and gradually admitting new states, until by 1848 the nation spanned the continent. During the second half of the 19th century, the American Civil War ended legal slavery in the country. By the end of that century, the United States extended into the Pacific Ocean, and the economy, driven in large part by the Industrial Revolution, began to soar.

The end of the Cold War and the dissolution of the Soviet Union left the United States as the sole superpower. The United States is a developed country and has the world’s largest national economy, benefiting from an abundance of natural resources and high worker productivity. While the U.S. economy is considered post-industrial, the country continues to be one of the world’s largest manufacturers.
