With a gross domestic product (GDP) of over $13 trillion, the U.S. has the largest national economy in the world. GDP per capita ranks first among the larger economies of the world, and third or eighth overall, depending on the measurement.

It adopted the current constitution (which has been amended several times subsequently) on September 17, 1787. The country greatly expanded in territory throughout the 19th century, acquiring further territory from Great Britain, as well as lands from France, Mexico, Spain, and Russia. With the collapse of the Soviet Union in 1991, it became the world's sole remaining superpower, and is a declared nuclear weapons state.

United States of AmericaBritain's American colonies broke with the mother country in 1776 and were recognized as the new nation of the United States of America following the Treaty of Paris in 1783. During the 19th and 20th centuries, 37 new states were added to the original 13 as the nation expanded across the North American continent and acquired a number of overseas possessions. The two most traumatic experiences in the nation's history were the Civil War (1861-65) and the Great Depression of the 1930s. Buoyed by victories in World Wars I and II and the end of the Cold War in 1991, the US remains the world's most powerful nation state. The economy is marked by steady growth, low unemployment and inflation, and rapid advances in technology.
