The U.S.A. is a federal republic of 50 states. Besides the 48 states that occupy the middle of the continent, the United States includes the state of Alaska at the north-western extreme of North America and the island state of Hawaii in the mid-Pacific Ocean. The national capital is Washington, which is coextensive with the District of Columbia, the federal capital region created in 1790.
The major characteristic of the United States is probably its great variety. Its physical environment ranges from the Arctic to the subtropical, from the moist rain forest to the arid desert, from the mountains to the flat prairie. Although the total population of the United States is large by world standards, its overall population density is relatively low.
The United States contains a highly diverse population. Its diversity has come from an immense and sustained global immigration. Probably no other country has a wider range of racial, ethnic and cultural types than does the United States. In addition to the presence of surviving native Americans (including American Indians, Aleuts and Eskimo) and the descendants of Africans taken as slaves to America, the national character has been enriched by the tens of millions of immigrants who have gone to America hoping for greater social, political and economic opportunities.
The United States is the world's greatest economic power, measured in terms of gross national product (GNP). Its exports and imports represent major proportions of the world total.

THE BEGINNINGS OF AMERICA
The question of the discovery of America is not a new one and it arose again in 1957 when an ancient map, called the Vinland Map, was found in London. It is a map of the world as it was known one thousand years ago and scientists think that it was made about 1440.
What is Vinland? Some British and American scientists believe that it was the Norsemen's name for North America. The Vinland Map shows Western Europe clearly with a coastline running from North Africa via Gibraltar and including the British Isles to Norway and the Arctic Ocean. It shows Iceland and Greenland.
According to the map, to the west of Greenland there is a great country the Norsemen called Vinland. The outlines of the coast of Vinland on the map correspond to those of the coast of Newfoundland and North America today.
The early people of Europe and the Near East were slow to discover the West mainly because of their fear of the open sea. But Icelandic sagas tell of a Norseman, Eiric the Red, and his son, about the voyages they made. They discovered Vinland at the end of the 10th century, built houses, wintered there and returned to Greenland. The ancient Norsemen left sailing instructions behind them.
It was Leif Ericson, the son of Eiric the Red, who in 999 reached the south shore of the land known now under the name of New England and encamped there. The sagas tell us that his men found there a lot of grape vines and grapes. The Norsemen filled their ship with grapes and sailed away, and Leif named the country Vinland (Wineland). Norsemen discoveries were transitory till it was rediscovered some five hundred years later.​
