Реферат: United States, history of the

Many peoples have contributed to the development of the United States of America, a vast nation that arose from a scattering of British colonial outposts in the New World. The first humans to inhabit the North American continent were migrants from northeast Asia who established settlements in North America as early as 8000 BC and possibly much earlier (see NORTH AMERICAN ARCHAEOLOGY). By about AD 1500 the native peoples of the areas north of the Rio Grande had developed a variety of different cultures (see INDIANS, AMERICAN). The vast region stretching eastward from the Rocky Mountains to the Atlantic Ocean was relatively sparsely populated by tribes whose economies were generally based on hunting and gathering, fishing, and farming.

VIKINGS explored the North American mainland in the 10th and 11th centuries and settled there briefly (see VINLAND). Of more lasting importance, however, was the first voyage (1492-93) of Christopher COLUMBUS, which inaugurated an age of great European EXPLORATION of the Western Hemisphere. Various European states (including Spain, France, England, the Netherlands, and Portugal) and their trading companies sent out expeditions to explore the New World during the century and a half that followed.
