United States Of America

Following the European colonization of the Americas, the United States became the world's first modern democracy after its break with Great Britain, with a Declaration of Independence in 1776. The original political structure was a confederation in 1777, ratified in 1781 as the Articles of Confederation. After long debate, this was supplanted by the Constitution of a more centralized federal government in 1789. During the 19th century, many new states were added to the original thirteen as the nation expanded across the North American continent and acquired a number of overseas possessions. Two of the major traumatic experiences in the nation's history were the American Civil War (1861-65) and the Great Depression of the 1930s. Buoyed by victories in World War I and World War II and the end of the Cold War in 1991, the U.S. remains the world's most powerful nation-state.

The United States of America consists of 50 states with limited autonomy in which federal law takes precedence over state law. In general, matters that lie entirely within state borders are the exclusive concern of state governments. These include internal communications; regulations relating to property, industry, business, and public utilities; the state criminal code; and working conditions within the state. Many state laws are quite similar from state to state. Finally, there are many areas of overlap between state and federal jurisdictions.

In recent years, the federal government has assumed broader responsibility in such matters as health, education, welfare, transportation, and housing and urban development. The constitutions of the various states differ in some details but generally follow a pattern similar to that of the federal Constitution, including a statement of the rights of the people and a plan for organizing the government. On such matters as the operation of businesses, banks, public utilities, and charitable institutions, state constitutions are often more detailed and explicit than the federal constitution.

The federal government itself consists of three branches: the executive branch, the legislative branch, and the judicial branch. The head of the executive branch is the President of the United States. The legislative branch consists of the United States Congress, while the Supreme Court of the United States is the head of the judicial branch. The President is elected to a four year term by the U.S. Electoral College. The various electors are in turn chosen primarily by the popular votes in the 50 states and the District of Columbia. Members of Congress are elected at varying dates, as are state Governors and state legislatures.

The federal and state government is dominated by two political parties, the Republicans and the Democrats. The dominant political culture in the United States is, as a whole, somewhat to the right of the dominant political culture in European democracies. Given their complex support bases it is difficult to specifically categorise the two major parties' appeal. Within the US political culture, the Republican Party is described as center-right and the Democratic Party is described as center-left. Minor party and independent candidates are very occasionally elected, usually to local or state office, but the United States political system has historically supported catch all parties rather than coalition governments. The ideology and policies of the sitting President of the United States commonly play a large role in determining the direction of his political party, as well as the platform of the opposition.

The two parties exist on both the state and federal level, although the parties' organization, platform, and ideologies are not necessarily uniform across all levels of government.

Both major parties draw some support from all the diverse socio-economic classes which compose the mature multi-ethnic capitalist society which makes up the United States. Business interests provide the major funding and support to the Republican Party while labor unions and minority ethnic groups provide major support to the Democrats. Access to funds is vital in the political system due to the financial costs of mounting political campaigns. Thus, through lobbying, corporations, unions, and other organized groups that provide funds and political support to parties and politicians can play a large role in determining the political agendas and government decision-making.

At the Declaration of Independence, the United States consisted of 13 states. In the following years, this number has grown steadily due to expansion to the west, conquest and purchase of lands by the American government, and division of existing states to the current number of 50 :

Alabama Alaska Arizona Arkansas California Colorado Connecticut Delaware Florida Georgia Hawaii Idaho Illinois Indiana Iowa Kansas Kentucky

Louisiana Maine Maryland Massachusetts Michigan Minnesota Mississippi Missouri Montana Nebraska Nevada New Hampshire New Jersey New Mexico New York North Carolina North Dakota

Ohio Oklahoma Oregon Pennsylvania Rhode Island South Carolina South Dakota Tennessee Texas Utah Vermont Virginia Washington West Virginia Wisconsin Wyoming

The contiguous part of the US (i.e. without Hawaii and Alaska) is called continental United States.

The states are divided into smaller administrative regions, called counties in most states--exceptions being Alaska (boroughs) and Louisiana (parishes). Counties can include a number of cities and towns, or sometimes just a part of a city. See County (United States).

Geography

As the world's third largest nation (land area), the United States landscape varies greatly: temperate forestland on the East coast, mangrove forests in Florida, the Great Plains in the centre of the country, the Mississippi-Missouri river system, the Rocky Mountains west of the plains, deserts and temperate coastal zones west of the Rocky Mountains and temperate rainforests in the Pacific Northwest. The arctic regions of Alaska and the volcanic islands of Hawaii only increase the geographic and climactic diversity.

The climate varies along with the landscape, from sub-tropic in Florida to tundra in Alaska. Large parts of the country have a continental climate, with warm summers and cold winters. Some parts of the United States, particularly parts of California, have a Mediterranean climate.

The economy of the United States is organized on the capitalist model and is marked by steady growth, low unemployment and inflation, a large trade deficit, and rapid advances in technology. The American economy can be regarded as the most important in the world. Several countries have coupled their currency with the dollar, or even use it as a currency, and the American stock markets are globally seen as an indicator of world economy.

The country has rich mineral resources, with extensive gold, oil, coal and uranium deposits. Agriculture brings the country among the top producers of, among others, maize, wheat, sugar and tobacco. American industry produces cars, airplanes and electronics. The biggest sector is however service industries; about three-quarters of Americans are employed in that sector.

The largest trading partner of the USA is its northern neighbor, Canada. Other major partners are Mexico, the European Union and the industrialized nations in the Far East, such as Japan and South Korea. Trade with China is also significant.

Most of the 280 million people currently living in the United States descend from European immigrants that have arrived since the establishment of the first colonies. Major components of the European segment of the United States population are descended from immigrants from Germany, England, Scotland, Ireland and Italy with many immigrants also from Scandinavian countries and the Slavic and other populations of eastern and southern Europe and French Canada; few immigrants came directly from France. Likewise, while there were few immigrants directly from Spain, Hispanics from Mexico and South and Central America are considered the largest minority group in the country, comprising 13.4% of the population (38.6 million people) in 2002. This has brought increasing use of the Spanish language in the United States (see Languages in the United States). About 12% (2000 census) of the people are African Americans who largely descend from the African slaves that were brought to America. A third significant minority is the Asian American population (3.6%), who are most concentrated on the West Coast. The native population of Native Americans, such as American Indians and Inuit make up less than 1% of the population.

American culture has a large influence on the rest of the world, especially the Western world. American music is heard all over the world, and American movies and television shows can be seen almost anywhere. This is in stark contrast to the early days of the American republic, when the country was generally seen as an agricultural backwater with little to offer the culturally advanced world centers of Asia and Europe. Nearing the end of its third century, nearly every major American city offers classical and popular music; historical, scientific and art research centers and museums; dance performances, musicals and plays; outdoor art projects and internationally significant architecture. This development is a result of both contributions by private philanthropists and government funding.

The United States is also a great center of higher education, boasting more than 1,500 universities, colleges, and other institutions of higher learning, the top tier of which include schools considered to be among the most prestigious and advanced in the world. Among these are the eight Ivy League Universities, elite private universities, numerous private colleges, which provide primarily undergraduate education, and an extensive system of public universities and colleges.
