How old is the history of America?

The United States was founded on July 4th, 1776. On this day, the American Declaration of Independence was adopted, and the United States declared its independence from Britain. By 2023, the United States will be 247 years old! The United States is a country founded by immigrants, and its history can be traced back to the beginning of17th century.

At that time, Britain established a colony in North America, which attracted many immigrants from other European countries. /kloc-In the middle of the 0/7th century, the British colony in North America expanded to the southern part of the United States today. But with the passage of time, Britain's control over the colonies became stricter and stricter, and immigrants began to feel dissatisfied and began to demand more autonomy.

1In the early 1970s, the conflict between American colonists and the British government escalated, and finally the American War of Independence broke out in 1775. The war lasted for eight years, and finally Britain recognized the independence of the United States in 1783. Since then, the United States began a period of rapid development, expanding its territory and forming today's American territory.

Early American civilization:

More than 40 thousand years ago, Indian ancestors arrived in North America through Asia, and then to Central America and South America; When Christopher Columbus arrived in what he thought was the New World, about 30 million Indians lived in America.

About 654.38+500,000 Indians live in the United States and Canada. The composition of these indigenous people is very different in heredity, language and society. It is estimated that in the15th century, there were at least 400 unrelated and distinctive cultural forms, personality types and language families north of the Rio Grande.

About 10 thousand years ago, another group of Asians moved to northern North America, which became the Eskimos. The first white people to come to America may be vikings. Some people think that they went to the east coast of North America before 1000 years ago.
