United States
officially United States of AmericaFederal republic,North America.
It comprises 48 contiguous states occupying the mid-continent,Alaska at the northwestern extreme of North America,and the island state of Hawaii in the mid-Pacific Ocean.The U.S.is a republic with two legislative houses; its head of state and government is the president.The territory was originally inhabited for several thousand years by numerous American Indian peoples who had probably emigrated from Asia.European exploration and settlement from the 16th century began displacement of the Indians.The first permanent European settlement,by the Spanish,was at Saint Augustine,Fla.,in 1565; the British settled Jamestown,Va.(1607); Plymouth,Mass.(1620); Maryland (1634); and Pennsylvania (1681).The British took New York,New Jersey,and Delaware from the Dutch in 1664,a year after the Carolinas had been granted to British noblemen.The British defeat of the French in 1763 (see French and Indian War) assured British political control over its 13 colonies.Political unrest caused by British colonial policy culminated in the American Revolution (1775–83) and the Declaration of Independence (1776).The U.S.was first organized under the Articles of Confederation (1781),then finally under the Constitution (1787) as a federal republic.Boundaries extended west to the Mississippi River,excluding Spanish Florida.Land acquired from France by the Louisiana Purchase (1803) nearly doubled the country's territory.The U.S.fought the War of 1812 against the British and acquired Florida from Spain in 1819.In 1830 it legalized removal of American Indians to lands west of the Mississippi River.Settlement expanded into the Far West in the mid-19th century,especially after the discovery of gold in California in 1848 (see gold rush).Victory in the Mexican War (1846–48) brought the territory of seven more future states (including California and Texas) into U.S.hands.The northwestern boundary was established by treaty with Great Britain in 1846.The U.S.acquired southern Arizona by the Gadsden Purchase (1853).It suffered disunity during the conflict between the slavery-based plantation economy in the South and the free industrial and agricultural economy in the North,culminating in the American Civil War and the abolition of slavery under the 13th Amendment.After Reconstruction (1865–77) the U.S.experienced rapid growth,urbanization,industrial development,and European immigration.In 1877 it authorized allotment of American Indian reservation land to individual tribesmen,resulting in widespread loss of land to whites.By the end of the 19th century,it had developed foreign trade and acquired outlying territories,including Alaska,Midway Island,the Hawaiian Islands,the Philippines,Puerto Rico,Guam,Wake Island,American Samoa,the Panama Canal Zone,and the Virgin Islands.The U.S.participated in World War I in 1917–18.It granted suffrage to women in 1920 and citizenship to American Indians in 1924.The stock market crash of 1929 led to the Great Depression.The U.S.entered World War II after the Japanese bombing of Pearl Harbor (Dec.7,1941).The explosion by the U.S.of an atomic bomb on Hiroshima (Aug.6,1945) and another on Nagasaki (Aug.9,1945),Japan,brought about Japan's surrender.Thereafter the U.S.was the military and economic leader of the Western world.
