European colonization of the Americas started with an attempt by the Vikings who came from Scandinavia, the north end of Europe around the year 1000. They explored and settled awhile in the colony they called Vinland in what was later called Newfoundland. However, they abandoned it.
In 1492 Columbus reached America. Soon Spanish conquistadores and many other Europeans went to stay. Different European countries took different territories, and fought over who should get which land. Natives died in great numbers. The survivors lost most of their land, and most learned the language of their conquerors.
After a series of wars in the late 18th and early 19th centuries, most of the colonies became independent countries.
