When did people start living in America?

The American nation originally came from all over the world, with many different cultures, races and religions. After a long period of existence and combination, they gradually became proud of being Americans. /kloc-Before 0/7th century, only Indians and Eskimos lived in Yuan Ye in North America, but after more than 100 years of immigration, it has become a new home for people of all European countries, the most important of which is the colony of 13, which was established by the British and declared its independence from Britain. After several consultations and reforms, the federal United States officially entered the world stage on the eve of the French Revolution. Early America welcomed immigrants, and these immigrants made her grow rapidly. The population of the United States was only 3 million in 1776, and now it has exceeded 200 million. In the process of rapid population growth, new living space is constantly opened up, and the direction has always been from east to west. The pioneers of frontier expansion not only engaged in agriculture and animal husbandry, but also looked for minerals and other resources. In the 20th century, the United States became not only the most powerful country in the world, but also an advanced country in science, technology, medicine and military power.

Before the colonial period (1607)

More than 20,000 years ago, a group of vagrants from Asia came to Central and South America through North America. These people are the ancestors of Indians. When Columbus discovered the New World, there were about 20 million Indians living in America, of whom about 1 10,000 lived in today's Canada and north-central America, and most of the rest lived in today's Mexico and South America. About 1 10,000 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. They are a group of adventurous fishermen. Some people think that they went to the east coast of North America 1 0,000 years ago.

Colonial period (1607 ~ 1753)

1607, a colonial group of about 100 people established Jamestown in Schabik Beach, which was the first permanent British colony in North America. In the next 150 years, many colonists came in and settled in the coastal areas, most of them came from Britain, and some came from France, Germany, the Netherlands, Ireland and other countries. 1In the middle of the 8th century, 13 British colonies gradually formed, with their own government and parliament under the supreme sovereignty of Britain. Due to the differences in climate and geographical environment, these 13 colonies have different economic forms, political systems and concepts.

Independent movement (1754 ~ 1783)

/kloc-In the middle of the 0/8th century, there was a rift between the British colonies in the United States and Britain. The expansion of the colonies made them consciously persecuted in Britain, and they had the idea of independence. 1774, representatives from 12 states gathered in Philadelphia to hold the so-called first continental congress, hoping to find a reasonable way to solve the problem peacefully with Britain. But the British king insisted that the colony must unconditionally submit to the British king and accept punishment.

1775, the war was ignited in Massachusetts, and the second continental congress was held in May, which strengthened the determination of war and independence, issued the famous Declaration of Independence, and put forward sufficient reasons for fighting this war, which was also the key factor to win the final victory.

178 1, the American army won a decisive victory. 1783, the United States and Britain signed the Treaty of Paris, ending the War of Independence. The revolution successfully formed a new government (1784 ~ 18 19), which gave the American people the opportunity to express their political ideas in the form of legislation. 1787, a federal conference was held in Philadelphia, during which Washington was promoted as the chairman. They adopted the principle that the power of the central government is universal, but it must be carefully defined and explained. At the same time, they also accepted the fact that the national government must have the right to tax, mint money, adjust commerce, declare war and conclude treaties.

In addition, in order to prevent the central power from being too large, Montesquieu's political theory of balance of power is adopted, that is, three departments of equal cooperation and mutual checks and balances are set up in the government, that is, the legislative, administrative and judicial powers are reconciled and balanced with each other, and no power occupies a controlling position.
