Introduce American history.

1620, 102 The persecuted Puritans in England signed a contract with a company that immigrated to North America. On September 23rd, led by a priest named Preston, they set sail on the may flower for 66 days. This is the earliest immigrant in North America. Previously, there were only Indians in North America.

The American War of Independence was held at 1775- 178 1. If the country is founded, it should be counted from the day when George Washington, the first president of the United States, took office, that is, 1789, 16 April. As early as 1787, federal states.

As for the word America, it should be born at that time.

Before the War of Independence, this place was called a British North American colony, but it was certainly not as big as the United States now, that is, several eastern States became bigger and bigger, and it was not until the middle of the18th century that the consciousness of the American nation was formed.

So the United States was originally British and Indian, then there were blacks, then there were * * *, and then there were people everywhere, haha.

That's what I'm talking about. It's simpler.
