1. A country of central and northwest North America with coastlines on the Atlantic and Pacific oceans. It includes the noncontiguous states of Alaska and Hawaii and various island territories in the Caribbean Sea and Pacific Ocean. The original Thirteen Colonies declared their independence from Great Britain in 1776 and formed a government under the Articles of Confederation in 1781. A new constitution, adopted in 1787 and in effect after 1789, provided for a strong central government, and the nation soon began to expand westward. The Civil War (1861-1865) was a brief but tragic disruption in the unity of the nation. Since that time the United States has evolved into a vast, diversified economic power. Washington, D.C., is the capital and New York the largest city. Population, 249,632,692.
