The United States emerged from the Thirteen British Colonies established along the East Coast. Disputes with Great Britain over taxation and political representation led to the American Revolutionary War (1775–1783), which established the nation's independence. In the late 18th century, the U.S. began expanding across North America, gradually obtaining new territories, sometimes through war, frequently displacing Native Americans, and admitting new states. This was strongly related to belief in manifest destiny, and by 1848, the United States spanned the continent from east to west. Slavery was legal in the southern United States until the second half of the 19th century, when the American Civil War led to its abolition. The Spanish–American War and World War I established the U.S. as a world power, and the aftermath of World War II left the United States and the Soviet Union as the world's two superpowers. During the Cold War, both sides fought in the Korean and Vietnam Wars but avoided direct military conflict. They competed in the Space Race, culminating in the 1969 spaceflight that first landed humans on the Moon. The Soviet Union's dissolution in 1991 ended the Cold War, leaving the United States as the world's sole superpower. > > The United States is a federal presidential-constitutional republic with three separate branches of government, including a bicameral legislature. It is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, NATO, and other international organizations. It is a permanent member of the United Nations Security Council. Considered a melting pot of cultures and ethnicities, its population has been profoundly shaped by centuries of immigration. The United States ranks high in international measures of economic freedom, quality of life, education, and human rights; it has low levels of perceived corruption. However, it has been criticized for inequality, related to race, wealth, and income; use of capital punishment; high incarceration rates; and lack of universal health care. > > The United States is a highly developed country, and its economy accounts for approximately a quarter of global GDP and is the world's largest by GDP at market exchange rates. By value, the United States is the world's largest importer and second-largest exporter of goods. Although its population is only 4.2% of the world's total, it holds over 30% of the total wealth in the world, the largest share held by any country. Making up more than a third of global military spending, it is the foremost military power in the world and a leading political, cultural, and scientific force. > The United States [^1] **See**:: #### Related - [[First Amendment rights impacts groups not individuals]] - [[McCarthyism is an attack on totalitarianism not communism]] - [[Most rights were denied to Americans at its founding]] - [[Social control prevents Americans from practicing personal freedom]] #### [[America]] 44/0 - [^1]: [America](https://en.wikipedia.org/wiki/United%20States)
