What major wars have happened in American history?

List of wars with great influence in American history:

The founding period

■ American War of Independence1776-1783;

The American War of Independence (1775- 1783), or the American Revolutionary War, was originally a war between the British Empire and its revolutionaries in 13 colonies in North America. At first, the war was mainly aimed at the economic policy of the British Empire, but later, because France, Spain and the Netherlands joined the war against the British Empire, the scope of the war far exceeded that of British North America.

At the same time, many North American Indians were mobilized to participate in the war. During the war, Britain was able to take advantage of its naval superiority to occupy colonial coastal cities, but how to control rural areas made the British army extremely difficult. With the victory of the naval battle in Schabik, the British army surrendered in the battle of Yorktown at 178 1. 1783 Paris Treaty recognized the independence of the United States of America. During the War of Independence, many colonists fled thirteen colonies to escape the war and settled in the north. This war also prepared for Canada's independence in the future. Although the American revolution includes political and social development before and after the war, the terms American revolutionary war and American revolution are often used interchangeably. Only military activities are mentioned here. If you need a broader vision, including the origin and subsequent influence, please refer to the American Revolution. See American Revolution.

■ The Second War between the United States and Britain

18 12- 18 15

After the independence of the United States, the British Empire has been unwilling to fail in an attempt to recapture the colonies. At the same time, the United States also wants to buy western North America and liberate Canada controlled by Britain. 1812 June18, the United States declared war on Britain, and the US military launched an attack on Canada. Because of the shortage of troops, Britain bribed many North American Indians to attack the American army. Soon the American army was defeated, and important cities and fortresses such as Detroit were occupied by Britain.

In September, the British army attacked new york by land and water, and the British navy was wiped out and retreated to Canada. On February 24th, 65438, Britain and America signed the Ghent Peace Treaty, and Britain confirmed the independence of the United States. 1815 65438+10 In October, British troops attacked New Orleans, but were repelled by American troops. The war is over. In this war, the United States attacked the strong with the weak. Although it did not seize new territory, it made Britain completely give up its intention to conquer the United States. The United States also abandoned its plan to go north to Canada and turned south to attack Mexico.

In addition, from a neutral standpoint, we cannot simply say that Americans are not good to Indians, but Britain is better. Britain may have a better attitude towards American Indians, but it has done much more bad things in other parts of the world than Americans, such as the genocide of local aborigines in the war between Australia and Zulu.

■ westward expansion period (1820-1865)

The westward movement of the United States is a large-scale immigration and colonization movement in the United States, and it is a process of urbanization, industrialization and great integration of the American nation. This westward movement has had a great and far-reaching impact on American economy, politics and society. So far, an American history can be said to be a western colonial history to a great extent. It laid the foundation for the United States to develop into a powerful country.

■ American-Mexican War (1846 ~ 1848)

Plantations in Texas, Mexico, rebelled at 1835 and demanded to be merged into the United States. Mexico sent troops to suppress. So the United States invaded Texas and invaded Mexico. In May, the United States declared war on Mexico.

On April 18, the US military defeated President Santa Anna and the main force of the General Staff. On May 5th, American troops occupied Puebla and approached Mexico City. In August, American reinforcements arrived, and American troops defeated Mexican troops again in contreras. The two sides held peace talks and the talks broke down on September 7.

Through this small-scale war, the United States seized 2.3 million square kilometers of land and became a big country across the Atlantic and Pacific oceans, which is rare in the world. Mexico, which has just gained independence from Spain for more than ten years, has lost most of its territory and its strength has been greatly weakened. Since then, the United States has gained the status of a great American country.

However, the focus of the debate is not whether slavery should be abolished in the southern United States, but whether some newly joined States allow slavery, which is related to the balance of power distribution between free States and slave-holding States in the federal government.
