History


Indigenous peoples

The first inhabitants of North America migrated from Siberia across the Bering land bridge at least 12,000 years ago; the Clovis culture, which appeared around 11,000 BC, is believed to be the first widespread culture in the Americas. Over time, indigenous North American cultures grew increasingly sophisticated, and some, such as the

American Revolution, Revolutionary War and the early republic (1776–1820)

Cold War (1945–1991)

After World War II, the United States entered the Cold War, where geopolitical tensions between the U.S. and the Soviet Union led the two countries to dominate world affairs. The U.S. engaged in regime change against governments perceived to be aligned with the Soviet Union, and competed in the Space Race, culminating in the first crewed Moon landing in 1969. Domestically, the U.S. experienced economic growth, urbanization, and population growth following World War II. The civil rights movement emerged, with Martin Luther King Jr. becoming a prominent leader in the early 1960s. The Great Society plan of President
Lyndon Johnson Lyndon Baines Johnson (; August 27, 1908January 22, 1973), often referred to by his initials LBJ, was an American politician who served as the 36th president of the United States from 1963 to 1969. He had previously served as the 37th vice ...

The societal shift in the roles of women partly resulted in large increases in female labor participation in the 1970s, and by 1985 the majority of women aged 16 and older were employed. The late 1980s and early 1990s saw the collapse of the Warsaw Pact and the

The U.S. housing bubble culminated in 2007 with the Great Recession, the largest economic contraction since the Great Depression. Coming to a head in the 2010s, political polarization increased as sociopolitical debates on cultural issues dominated politics. This polarization was capitalized upon in the January 2021 Capitol attack, when a mob of insurrectionists entered the U.S. Capitol and attempted to prevent the peaceful transfer of power.

Climate

With its large size and geographic variety, the United States includes most climate types. East of the 100th meridian, the climate ranges from humid continental in the north to humid subtropical in the south. The western Great Plains are semi-arid.

In the American Southwest, droughts became more persistent and more severe.


Biodiversity and conservation

The U.S. is one of 17 megadiverse countries containing large numbers of endemic species: about 17,000 species of vascular plants occur in the contiguous United States and Alaska, and over 1,800 species of flowering plants are found in Hawaii, few of which occur on the mainland.

National government

Composed of three branches, all headquartered in Washington, D.C., the federal government is the national government of the United States. It is regulated by a strong system of checks and balances. * The U.S. Congress, a

and the House of Representatives, makes federal law, declares war, approves treaties, has the power of the purse, and has the power of impeachment. The Senate has 100 members (2 from each state), elected for a six-year term. The House of Representatives has 435 members, each elected for a two-year term; all representatives serve one congressional district of equivalent population. * The U.S. president is the commander-in-chief of the military, can veto legislative bills before they become law (subject to congressional override), and appoints the members of the Cabinet (subject to Senate approval) and other officials, who administer and enforce federal laws and policies through their respective agencies. Candidates for president campaign with a vice-presidential running mate. Both candidates are elected together, or defeated together, in a presidential election. Unlike other votes in American politics, this is technically an indirect election in which the winner will be determined by the

. There, votes are officially cast by individual electors selected by their state legislature. In practice, however, all 50 states choose a group of presidential electors who must confirm the winner of their state's popular vote. This group of electors equals their state's number of U.S. representatives, ''plus'' two more electors for the two U.S. senators the state sends to Congress. (The District of Columbia, with no representatives or senators, is allocated three electoral votes.) Both the president and the vice president serve a four-year term and may be reelected to the office only once, for one additional four-year term. * The U.S. federal judiciary, whose judges are all appointed for life by the president with Senate approval, consists primarily of the U.S. Supreme Court, the

Subdivisions

In the American federal system, sovereign powers are shared between two levels of elected government: national and state. People in the states are also represented by local elected governments, which are administrative divisions of the states. States are subdivided into counties or county equivalents, and further divided into municipalities. The District of Columbia is a federal district that contains the capital of the United States, the
