The official name of the United States is the United States of America.

The Commonwealth of North America. The territory includes 48 contiguous states in the mid-latitudes of the American continent, Alaska at the northwest tip of North America, and Hawaii, an island state in the central Pacific. Area: (including the Great Lakes) 9,529,063 square kilometers. Population: approximately 286,067,000 (2001). Capital: Washington, DC. The population includes whites, African Americans, Hispanics, Asians, Pacific Islanders, American Indians (Native Americans), Eskimos, and Aleuts. Languages: English (main language), Spanish.

Mountain ranges include the Appalachians, Ozarks, Rockies, Cascades, and Sierra Nevada. The lowest point is Death Valley, California. The highest point is Mount McKinley in the Alaska Range, while in the continental United States, the highest point is Mount Whitney. The major rivers are the Mississippi, Colorado, Columbia, and Rio Grande rivers. The Great Lakes, Great Salt Lake, and Lake Okeechobee are the largest lakes. The United States is the world's leading producer of certain minerals, including copper, silver, zinc, gold, coal, oil and natural gas; it is also a major exporter of food. Manufacturing includes steel products, chemicals, electronics and textiles. Other important industries are tourism, dairying, livestock farming, fishing and wood processing. The United States is a bicameral republic. The President is the head of state and head of government. The territory was settled thousands of years ago by some American Indians, probably from Asia. In the 16th century, Europeans came to explore and settle here and began to replace the Indians. The first permanent European settlement was St. Augustine, Florida, founded by the Spanish in 1565. Later the British established Jamestown, Virginia (1607), Plymouth, Massachusetts (1620), and Maryland (1634). and Pennsylvania (1681) established settlements. In 1664, a year after Carolina was granted the British nobility, the British took New York, New Jersey, and Delaware from the Dutch. The British defeated the French in 1763 (see French and Indian War) and gained political control of 13 colonies. The political turmoil caused by British colonial policy ended with the American War of Independence (1775-1783) and the Declaration of Independence (1776). The United States was first organized under the Articles of Confederation (1781) and finally became a federal republic through the Constitution (1787). The boundaries of the United States were later confirmed as far west as the Mississippi River, excluding the Spanish possession of Florida. Through the Louisiana Purchase of 1803, the United States nearly doubled its territory with land purchased from the French. The United States went to war with Britain in the War of 1812 and captured Florida from the Spanish in 1819. Legislation was passed in 1830 to relocate American Indians to lands west of the Mississippi River. Expansion to the west began in the mid-19th century, especially after the discovery of gold in California in 1848 (see gold rush). The victory of the United States in the Mexican War (1846-1848) resulted in the annexation of part or all of the territory of seven subsequent states (including California and Texas) to the United States. In 1846, the United States signed a treaty with Great Britain to establish its northwest boundaries, and in 1853, it acquired land in southern Arizona in the Gadsden Purchase. Later, the conflicts between the slave-holding plantation economy in the South and the free industrial and agricultural economy in the North split the United States, and the Civil War broke out (1861-1865, see American Civil War [American Civil War]). The Thirteenth Amendment to the Constitution abolished slavery. After the Reconstruction period (1865-1877), the United States experienced rapid development, urbanization, industrial development and European immigration. In 1877, the United States allowed land on Indian reservations to be given to individual tribal members, resulting in large tracts of land falling into white hands. By the end of the 19th century, the United States had developed foreign trade and acquired overseas territories, including Alaska, Midway, the Hawaiian Islands, the Philippine Islands, Puerto Rico, Guam, Wake Island, American Samoa, the Panama Canal Zone, and the Virgin Islands.

From 1917 to 1918, the United States participated in World War I. Granted suffrage to women in 1920; citizenship to American Indians in 1924. The stock market crash of 1929 led to the Great Depression. After the Japanese attack on Pearl Harbor (1941-12-07), the United States entered World War II. The United States dropped the first atomic bomb on Hiroshima, Japan (1945-08-06) and the second atomic bomb on Nagasaki (1945-08-09), which ended the war and made the United States the leader of the Western world. The United States participated in the post-war reconstruction work in Europe and Japan, but was trapped in a 40-year Cold War confrontation with the Soviet Union. The United States entered the Korean War. Puerto Rico was granted autonomous status in 1952. In 1954, racial segregation in American schools was declared a violation of the U.S. Constitution. In 1959 Alaska and Hawaii became two states of the United States. In 1964, Congress passed the Civil Rights Act and authorized comprehensive intervention in the Vietnam War. In the mid-to-late 1960s, riots occurred across the United States, including race riots and anti-war demonstrations. In 1969, the United States completed the first human landing on the moon. In 1973, all U.S. troops withdrew from Vietnam. In the Persian Gulf War (1991), the United States led the coalition to attack Iraq. In 1992, troops were sent to Somalia to rescue hungry people. In 1995 and 1999, he joined NATO in air strikes against Serbian forces in the former Yugoslavia. In 1998, President W.J. Clinton became the second president to be impeached by the U.S. House of Representatives; in 1999, he was acquitted by the Senate. Management of the Panama Canal was transferred to Panama in 1999. In 2000, G.W. Bush became the first person since 1888 to be elected president by the Electoral College despite receiving slightly fewer votes than his opponent A. Gore. After the terrorist attacks on September 11, 2001 destroyed part of the World Trade Center and the Pentagon, the United States sent troops to attack the Taliban government in Afghanistan on the grounds that it was hiding and refusing to extradite bin Laden, the suspected mastermind of the terrorist activities.
