Why is there no ancient history in America?

North America was originally inhabited by Indians. By the end of 15, Spain, Britain and other countries began to immigrate to North America. Now the United States was formally established in 1776, less than 300 years ago. Basically, it can be said that all countries are immigrants from the beginning, which is why the United States has no history.

The United States was originally a place where Indians lived. At the end of 15, Spain, the Netherlands, France and Britain immigrated here one after another. 13 Before the 8th century, Britain established13 British North American colony on the Atlantic coast of the United States. 1775, the American people broke out the war of independence against the colonial rule of the British Empire. 1776 On July 4th, the Second Continental Congress was held in Philadelphia. George Washington served as commander of the Continental Army and issued the Declaration of Independence, announcing the formal establishment of the United States of America. 1783 At the end of the War of Independence, Britain recognized the independence of 13 colonies. 1787, the constitution of the United States was adopted and a federal state was established. From 186 1 to 1865, the American Civil War broke out. Abraham lincoln led the free states in the north and defeated the slave states in the south. Since then, the United States has ended the "semi-slave and semi-free state" and started to implement free capitalism in an all-round way, and embarked on the road of rapid development. During the period of 1803- 1959, we continued to expand our territory through purchase and war.
