Long ago, a law was made. 
Long ago, many people came from China. 

In the 1800s, many people came from China to the United States. 

The Chinese Exclusion Act was a major law in United States history.
Many things led to this law being passed. In the 1800s, China faced many hard problems like poverty and famine. 

As time went on, many people in the U.S. grew angry at Chinese workers. They blamed Chinese labor for low wages after the economy slowed down in 1873. 
Congress tried to pass different laws to stop immigration before 1882. In 1880, the Angell Treaty allowed the U.S. to suspend immigration. President Rutherford B. Hayes once vetoed a law that would have banned immigration for twenty years. 
This era of exclusion lasted for many decades. The law was finally ended by the Chinese Exclusion Repeal Act in 1943. This new law allowed 105 Chinese immigrants to enter the U.S. each year. Later, the Immigration and Nationality Act of 1952 removed racial barriers. Then, the Immigration and Nationality Act of 1965 changed the rules again. These changes helped people from many different places move to the United States. It shows how laws can change how the whole world connects.
The Chinese Exclusion Act of 1882 was a major United States federal law.
Many Chinese immigrants arrived in America during the 19th century due to upheaval in China. Poverty, droughts, and famines caused many people to seek new lives elsewhere. People also fled violent conflicts like the Taiping Rebellion and the Punti-Hakka Clan Wars. These wars claimed as many as one million lives. Most immigrants came from Sze Yup and spoke Taishanese. They arrived during the California gold rush of 1848–1855. Later, they provided essential labor for projects like the first transcontinental railroad. 
The mechanism of exclusion involved several specific legal steps and restrictions. First, the law targeted "laborers" specifically, while making exceptions for diplomats, teachers, students, and merchants. Second, it created a system of identification for those traveling. Chinese people moving in or out of the country had to carry a certificate to prove their status. Without this paper, they risked deportation. Third, the law prevented existing residents from gaining citizenship. These rules worked together to limit the growth of the Chinese community in America.
Hostility toward Chinese immigrants grew due to economic and political reasons. In the 1870s, the U.S. economy declined following the Panic of 1873. Many workers blamed Chinese "coolie" labor for depressed wage levels. At one point, Chinese men represented nearly one-quarter of all wage-earning workers in California. Labor leaders like Denis Kearney and his Workingman's Party used this anger to gain influence. They turned economic frustration into political movements. This sentiment was often expressed through racist views and even violent protests in cities like Los Angeles.
Politicians used the election year of 1876 to turn a state issue into a national one. California leaders wanted to influence national political parties to gain West Coast votes. They held large demonstrations, such as a gathering in San Francisco on April 5 that drew 20,000 people. They also sent delegations to eastern cities to spread anti-Chinese sentiment. In 1875, the Page Act was passed to ban Chinese women from entering. This was a specific attempt to prevent Chinese families from settling permanently. 
The law went through several stages of strengthening over many years. The 1882 Act was initially intended to last only ten years. However, it was renewed and made stronger by the Geary Act in 1892. By 1902, these restrictive laws were made permanent. The legal system did provide some resistance to these changes. In 1898, the Supreme Court ruled in United States v. Wong Kim Ark that the law did not stop children born in the U.S. from being citizens. 
Exclusion finally ended through a series of legislative changes in the 20th century. The Chinese Exclusion Repeal Act was passed in 1943. This act repealed the exclusion and allowed 105 Chinese immigrants to enter the U.S. each year. Later, the Immigration and Nationality Act of 1952 abolished direct racial barriers. Finally, the Immigration and Nationality Act of 1965 abolished the National Origins Formula. These laws changed how the United States connects with the rest of the world.
