The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
Zambia the Republic of Zambia, is a landlocked country in south-central Africa. It neighbours the Democratic Republic of the Congo to the north, Tanzania to the north-east, Malawi to the east, Mozambique to the southeast and Botswana to the south, Namibia to the southwest, Angola to the west; the capital city is Lusaka, located in the south-central part of Zambia. The population is concentrated around Lusaka in the south and the Copperbelt Province to the northwest, the core economic hubs of the country. Inhabited by Khoisan peoples, the region was affected by the Bantu expansion of the thirteenth century. After visits by European explorers in the eighteenth century, the region became the British protectorates of Barotziland-North-Western Rhodesia and North-Eastern Rhodesia towards the end of the nineteenth century; these were merged in 1911 to form Northern Rhodesia. For most of the colonial period, Zambia was governed by an administration appointed from London with the advice of the British South Africa Company.
On 24 October 1964, Zambia became independent of the United Kingdom and prime minister Kenneth Kaunda became the inaugural president. Kaunda's socialist United National Independence Party maintained power from 1964 until 1991. Kaunda played a key role in regional diplomacy, cooperating with the United States in search of solutions to conflicts in Rhodesia and Namibia. From 1972 to 1991 Zambia was a one-party state with the UNIP as the sole legal political party under the motto "One Zambia, One Nation". Kaunda was succeeded by Frederick Chiluba of the social-democratic Movement for Multi-Party Democracy in 1991, beginning a period of social-economic growth and government decentralisation. Levy Mwanawasa, Chiluba's chosen successor, presided over Zambia from January 2002 until his death in August 2008, is credited with campaigns to reduce corruption and increase the standard of living. After Mwanawasa's death, Rupiah Banda presided as Acting President before being elected President in 2008. Holding office for only three years, Banda stepped down after his defeat in the 2011 elections by Patriotic Front party leader Michael Sata.
Sata died on 28 October 2014. Guy Scott served as interim president until new elections were held on 20 January 2015, in which Edgar Lungu was elected as the sixth President. In 2010, the World Bank named Zambia one of the world's fastest economically reformed countries; the Common Market for Eastern and Southern Africa is headquartered in Lusaka. The territory of what is now Zambia was known as Northern Rhodesia from 1911, it was renamed Zambia at independence in 1964. The new name of Zambia was derived from the Zambezi river; the area of modern Zambia is known to have been inhabited by the Khoisan until around AD 300, when migrating Bantu began to settle around these areas. These early hunter-gatherer groups were either annihilated or absorbed by subsequent more organised Bantu groups. Archaeological excavation work on the Zambezi Valley and Kalambo Falls show a succession of human cultures. In particular, ancient camping site tools near the Kalambo Falls have been radiocarbon dated to more than 36,000 year ago.
The fossil skull remains of Broken Hill Man, dated between 300,000 and 125,000 years BC, further shows that the area was inhabited by early humans. The early history of the peoples of modern Zambia can only be gleaned from knowledge passed down by generations through word of mouth. In the 12th century, waves of Bantu-speaking immigrants arrived during the Bantu expansion. Among them, the Tonga people were the first to settle in Zambia and are believed to have come from the east near the "big sea"; the Nkoya people arrived early in the expansion, coming from the Luba–Lunda kingdoms in the southern parts of the modern Democratic Republic of the Congo and northern Angola, followed by a much larger influx between the late 12th and early 13th centuries To the east, the Maravi Empire spanning the vast areas of Malawi and parts of modern northern Mozambique began to flourish under Kalonga. At the end of the 18th century, some of the Mbunda migrated to Barotseland, Mongu upon the migration of among others, the Ciyengele.
The Aluyi and their leader, the Litunga Mulambwa valued the Mbunda for their fighting ability. In the early 19th century, the Nsokolo people settled in the Mbala district of Northern Province. During the 19th century, the Ngoni and Sotho peoples arrived from the south. By the late 19th century, most of the various peoples of Zambia were established in their current areas; the earliest European to visit the area was the Portuguese explorer Francisco de Lacerda in the late 18th century. Lacerda led an expedition from Mozambique to the Kazembe region in Zambia, died during the expedition in 1798; the expedition was from on led by his friend Francisco Pinto. This territory, located between Portuguese Mozambique and Portuguese Angola, was claimed and explored by Portugal in that period. Other European visitors followed in the 19th century; the most prominent of these was David Livingstone, who had a vision of ending the slave trade through the "3 Cs": Christianity and Civilization. He was the first European to see the magnificent waterfalls on the Zambezi River in 1855, naming them the Victoria Falls after Queen Victoria of the United Kingdom.
He described them thus: "Scenes so lovely must have been gazed upon by angels in their flight". Locally the falls are known as "Mosi-o-Tunya" or "thunder
1996 Summer Olympics
The 1996 Summer Olympics known as the Games of the XXVI Olympiad known as Atlanta 1996, referred to as the Centennial Olympic Games, were an international multi-sport event, held from July 19 to August 4, 1996, in Atlanta, United States. These Games, which were the fourth Summer Olympics to be hosted by the United States, marked the century of the 1896 Summer Olympics in Athens—the inaugural edition of the modern Olympic Games, they were the first since 1924 to be held in a different year from a Winter Olympics, under a new IOC practice implemented in 1994 to hold the Summer and Winter Games in alternating, even-numbered years. More than 10,000 athletes from 197 National Olympic Committees competed in 26 sports, including the Olympic debuts of beach volleyball, mountain biking, softball, as well as the new disciplines of lightwight rowing and women's football. 24 countries made their Summer Olympic debut in Atlanta, including eleven former Soviet republics participating for the first time as independent nations.
The hosting United States led the medal count with a total of 101 medals, the most gold and silver medals out of all countries. The U. S. topped the medal count for the first time since 1984, for the first time since 1968 in a non-boycotted Summer Olympics. Notable performances during competition included those of Andre Agassi—who became the first men's singles tennis player to combine a career Grand Slam with an Olympic gold medal, Donovan Bailey—who set a new world record of 9.84 for the men's 100 meters, Lilia Podkopayeva—who became the second gymnast to win an individual event gold after winning the all-round title in the same Olympics. The festivities were marred by violence on July 27, when Eric Rudolph detonated pipe bombs at Centennial Olympic Park—a downtown park, built to serve as a public focal point for the Games' festivities, injuring 111. In 2003, Rudolph confessed to the bombing and a series of related attacks on abortion centers and a gay bar, was sentenced to life in prison.
He claimed that the bombing was meant to protest the U. S. government's sanctioning of "abortion on demand". The Games turned a profit, helped by record revenue from sponsorship deals and broadcast rights, reliance on private funding, among other factors; the Games faced criticism for being overly commercialized, as well as other issues noted by European officials, such as the availability of food and transport. The event had a lasting impact on the city. Atlanta was selected on September 18, 1990, in Tokyo, over Athens, Manchester and Toronto at the 96th IOC Session; the city entered the competition as a dark horse. The US media criticized it as a second-tier city and complained of Georgia's Confederate history. However, the IOC Evaluation Commission ranked Atlanta's infrastructure and facilities the highest, while IOC members said that it could guarantee large television revenues similar to the success of the 1984 Summer Olympics in Los Angeles. Additionally, former US ambassador to the UN and Atlanta mayor Andrew Jackson Young touted Atlanta's civil rights history and reputation for racial harmony.
Young wanted to showcase a reformed American South. The strong economy of Atlanta and improved race relations in the South helped to impress the IOC officials; the Atlanta Committee for the Olympic Games proposed a substantial revenue-sharing with the IOC, USOC, other NOCs. Atlanta's main rivals were Toronto, whose front-running bid that began in 1986 had chances to succeed after Canada had held a successful 1988 Winter Olympics in Calgary, Melbourne, who hosted the 1956 Summer Olympics and after Brisbane, Australia's failed bid for the 1992 games and prior to Sydney, Australia's successful 2000 Summer Olympics bid; this would be Toronto's fourth failed attempt since 1960. Greece, the home of the ancient and first modern Olympics, was considered by many observers the "natural choice" for the Centennial Games. However, Athens bid chairman Spyros Metaxa demanded that it be named as the site of the Olympics because of its "historical right due to its history", which may have caused resentment among delegates.
Furthermore, the Athens bid was described as "arrogant and poorly prepared", being regarded as "not being up to the task of coping with the modern and risk-prone extravaganza" of the current Games. Athens faced numerous obstacles, including "political instability, potential security problems, air pollution, traffic congestion and the fact that it would have to spend about $3 billion to improve its infrastructure of airports, rail lines and other amenities"; the total cost of the 1996 Summer Olympics was estimated to be around $1.7 billion. The venues and the Games themselves were funded via private investment, the only public funding came from the U. S. government for security, around $500 million of public money used on physical public infrastructure including streetscaping, road improvements, Centennial Olympic Park, expansion of the airport, improvements in public transportation, redevelopment of public housing projects. $420 million worth of tickets wer
