Newfoundland, Canada found their footprints, but the pirates failed to establish permanent residence and soon lost contact with the New World.

500 years later, the demand for Asian spices, textiles and dyes prompted European navigators to dream of finding a route to shorten the distance between East and West. 1492, Italian navigator Christopher? On behalf of the Spanish royal family, Columbus sailed west from Europe and landed on an island in the Bahamas in the Caribbean. Spanish explorers spent 40 years building a huge empire in Central and South America. In the16th and17th centuries, the Nordic people began to settle on the present northeastern coast of the United States, which soon became a British territory and remained a British colony until the18th century revolutionary war.

Early America welcomed foreign immigrants, which 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, we are constantly exploring new living space, and the direction has always been from east to west. Pioneers not only engaged in agriculture and animal husbandry, but also looked for minerals and other resources. In the 20th century,

4. How long is the history of America? Mayflower: Before 1620 (1607 years ago) the first pilgrims arrived in the colonial period of North America, there were a group of vagrants from Asia who came to Central and South America through North America more than 20,000 years ago. 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. During the colonial period (1607-1753)1607, a colonial group of about1000 people established Jamestown in Kikuk Beach, which was the first permanent colony established by Britain in North America. In the following 150 years, many colonists came in.

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.

Independence Movement (1754-1783)1In the middle of the 8th century, there was a rift between Britain and American colonies. 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 broke out in Massachusetts; 1776 in may, the second continental congress was held in Philadelphia, 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 us military 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. Expansion to the West (1820-1849) 65438+At the beginning of the 9th century, thousands of people crossed the Appalachian Mountains and migrated westward.

Some pioneers moved to the border of the United States and even went deep into the territory of Mexico and Oregon between Alaska and California. Pioneers bravely and diligently sought a better life in the west.

The causes of civil war (1850- 1869) are not only economic, political and military issues, but also ideological conflicts. The civil war exposed America's weakness.

The existence of this country has been tested. After this test, the United States embarked on the road of a centralized and modern country.

There is a dispute between the north and the south on the issue of slavery. The main policy of the south in national politics is to protect and expand the interests represented by the "cotton and slavery" system; The northern States are mainly manufacturing, commercial and financial centers, and there is no need to rely on slaves for these production. This kind of economic and political conflict has a long history. In the early 1960s, 1 1 Southern states broke away from the federation and formed another government, while the North said that it would do whatever it took to achieve reunification.

186 1 year, the civil war broke out. Americans fought face to face for four years, and the south was severely damaged, leaving deep scars. 1865, the defeat of the north not only shows the reunification of the United States, but also shows that slavery is no longer practiced in the whole country.

Industrialization and Reform (1870-1929)1At the beginning of the 9th century, the United States began to industrialize, but it entered a mature stage after the civil war. In less than 50 years from the Civil War to the First World War, the United States has changed from an agricultural country to an urbanized country.

Machines have replaced manual work, and products have greatly increased. The national railway network has improved the circulation of goods.

In order to meet the needs of the public, many new inventions have entered the market. The banking industry provides loans to promote the development of industry and commerce.

So the nearly 30 years from 1890 to 19 17 is called the so-called "progress period". 19 14, the world war broke out; 19 17, the United States was involved in the whirlpool of war and tried to play a new role in the world.

/kloc-The Great Depression, which began in 0/930, affected not only the United States, but also all countries in the world. The economic panic caused millions of workers to lose their jobs, a large number of farmers were forced to give up their farmland, factories and shops closed, banks closed down and there was a depression. 1932, Roosevelt was elected president.

He argued that the government should take action to end the Great Depression. Although the new government solved many difficulties, the American economy didn't wake up until World War II. After World War II, with the defeat of the Axis countries and the decline of the strength of Britain and France, the United States and the Soviet Union became superpowers, and the world was divided into two camps.

The United States and the Soviet Union and their respective camps stepped up military, political, economic and propaganda preparations, just like in wartime. This state is called "Cold War".

1976, the bicentennial of the founding of the United States, various celebrations were held all over the country. The United States finally brought down the Soviet Union in the Cold War. 199 1 With the disintegration of the Soviet Union, the United States became the only superpower in the world, and the ideological barriers between the two camps in the world were also broken.

In the ever-changing history of human development, America will turn a new page.
