The USA today is a multicultural society - this is largely due to the fact that a large number of people migrated there, mostly from Europe, in the early 1900s
The USA encouraged immigration with an Open Door policy. They hoped America would be a melting pot and the immigrants would be workers that would make the country richer
Traditionally, the immigrants had tended to come from northern and western Europe – Britain, Ireland, Germany - and were White Anglo Saxon Protestants (WASPs)
Reasons why some Americans became angry towards the 'new' immigrants
They were often poor
Many were illiterate and could not speak English
Many were Roman Catholics or Jews, therefore from a different cultural and religious background
The fear of communism spread following the Bolshevik revolution in 1917, and the trauma of World War One, worried many Americans and contributed to the Red Scare in 1919
Immigrants had to pass a series of reading and writing tests. Many of the poorer immigrants, especially those from eastern Europe, had received no education and therefore failed the tests and were refused entry
A law which restricted the number of immigrants to 357,000 per year, and also set down a quota - only 3 per cent of the total population of any overseas group already in the USA in 1910 could come in after 1921
This law cut the quota of immigrants to 2 per cent of its population in the USA in 1890. The act was aimed at restricting southern and eastern Europeans immigrants. It also prohibited immigration from Asia and this angered the Chinese and Japanese communities that were already in the USA
In September 1920, a bomb exploded on Wall Street killing 38 people, and another bomb destroyed the front of the Attorney General, A Mitchell Palmer's house
United States Attorney General, A Mitchell Palmer organised attacks against left wing organisations. Palmer spread rumours about the Red Scare saying that there were around 150,000 communists living in the country (0.1 per cent of the population). As many as 6,000 were arrested and held in a prison without a hearing and hundreds were deported
Nicola Sacco and Bartolomeo Vanzetti were Italian immigrants. The two men acknowledged that they were radicals and that they had avoided serving in World War One. In May 1920 Sacco and Vanzetti were arrested and accused of armed robbery on a shoe factory, during which a significant amount of money was stolen and two people were killed
Although 61 witnesses said they had seen them, the defence had 107 witnesses alleging that they had seen them somewhere else when the crime was committed
During the court case in May 1921, Judge Webster Thayer was prejudiced against the two men. Although a man named Celestino Madeiros later admitted that he had committed the crime, Sacco and Vanzetti lost their appeal. In August 1927 they were both executed by electrocution in Charlestown prison
Religious freedom came to America in 1791, when the First Amendment to the Constitution was passed. This stated that America should not be dominated by one Church
A new kind of conservative Christianity that emerged after World War One. The Fundamentalists believed strongly and literally in everything the Bible said, and in the Bible Belt they condemned any other beliefs
Native Americans' attitudes about land and ownership were in complete contrast to the consumerism of 1920s USA. By the end of the 19th century they had been forced to live on poor quality land in specified reservations, where they were encouraged to reject their own culture and integrate into the prevailing white Christian culture
In 1925 the ideas of the Fundamentalists gained much publicity in America. A new law was passed in six states, including Tennessee, prohibiting the teaching of Charles Darwin's evolution ideas in schools because those ideas contradicted the story of the Creation in the Bible
John Scopes took the decision to teach his pupils about Darwin and evolution in his biology lessons in order to make a political point. He was arrested for breaking the law
