America is only two or three hundred years old. This means that there has never been a country like the United States before. So how was the United States established?

The founding process of the United States is as follows:

149210 June 12, with the support of the queen of Spain, Columbus arrived in San Salvador Island, Bahamas. From 65438 to 0493, Columbus established the first Spanish colony in present-day Santo Domingo. At first, the aborigines in North America enthusiastically helped the immigrants, but in return, they were killed, driven away and enslaved by colonists, and the aborigines began to be colonized.

1607, the Virginia Company in London established the first short-lived British colony in Jamestown, chesapeake bay, North America. Since then, Britain has successively established colonies in the northeast and central parts of the Atlantic coast of North America. 1624, the Netherlands established a colony at the mouth of the Hudson River-New Holland, and expanded to Connecticut and Delaware Valley in the following decades.

After the three Anglo-Dutch wars from 1652 to 1675, the Netherlands permanently withdrew from North America, and Britain got the new Netherlands and continued to expand its colonies. By the time of the American Revolution in 1775, Britain had established 13 colonies on the Atlantic coast of North America.

1760s and1770s,13the tension between the North American colonies and Britain led to a series of armed conflicts in 1774 and 1775. On July 4th, 1976, 13 colonial representatives attending the Second Continental Congress signed the American Declaration of Independence, which turned the armed conflict into a war of independence. At the meeting, the delegates decided to build a continental army, led by Joe Washington, to fight against the British.

178 1 year, 13 constituent states all passed the Confederacy Regulations, and the permanent confederation was established. After an arduous war of independence, the Continental Legion finally defeated the British army, which made Britain sign the Treaty of Paris in 1783, officially recognizing the independence of 13 North American colonies.

At the constitutional conference of 1787, a constitution was put forward to transform the confederation into federalism. In June of A.D. 1789, the Constitution of the United States of America came into effect after nine of the three confederate states were adopted, and the first federal state in history was established.

Location context:

The United States is the second largest country in the Americas, and its territory includes the mainland of the United States, Alaska in the northwest of North America and the Hawaiian Islands in the central Pacific Ocean. The area is 93726 10 square kilometer. If the U.S. sovereign part of the Great Lakes is about 170 square kilometers, and the coastal waters such as estuaries, harbors and inland seas are included, the total area is 9.63 million square kilometers. If only the land area is counted, the United States ranks third, second only to Russian and China.

Terrain:

The terrain of the United States is changeable, with high terrain in the west and low terrain in the east. There are coastal plains on the east coast, which are wide in the south and narrow in the north, extending to New Jersey and Long Island, and there are also some glacial sedimentary plains. Behind the coastal plain is a hilly area with undulating terrain, extending all the way to the Appalachian Mountains in North Carolina and New Hampshire, with an altitude of 1, 830 meters.

To the west of the Appalachian Mountains is the central plain of the United States, with relatively flat terrain. The Great Lakes and the Mississippi-Missouri River Basin are the earliest in the world.

Four major rivers are also located here. To the west of the Mississippi River, the topography of the internal plain began to rise, and finally it entered the great plain with a vast area and few topographical features in the central United States.

In the west of the Great Plains, there is the majestic Rocky Mountains, which bisects the American mainland from south to north, with the highest peak of 4,270 meters in Colorado. There are Sierra Nevada and coastal mountains on the west coast. The highest mountain in the United States is Mount McKinley, which is 6 193 meters above sea level and the highest peak in North America.
