Final answer:
After 1890, there was a shift in the countries from which European immigrants came to the United States, leading to increased diversity among immigrants. This shift had effects on American attitudes about immigrants, resulting in prejudice, discrimination, and changes in immigration policies.
Step-by-step explanation:
After 1890, there was a shift in the countries from which European immigrants came to the United States. Prior to 1890, the majority of European immigrants were from Western Europe, such as Ireland and Germany. However, after 1890, there was a significant increase in immigrants from Southern and Eastern Europe, including countries like Italy, Greece, Russia, and Poland. This shift in immigration patterns led to increased diversity among immigrants in terms of language, culture, and religion.
The influx of new immigrants had various effects on American attitudes about immigrants. Many Americans, especially those of the 'old-stock' population, held prejudice against the 'new' immigrants due to their differences in appearance, language, religion, and customs. As a result, these new immigrants faced discrimination and were often blamed for various societal problems.
Furthermore, this increase in immigration from different countries led to changes in immigration policies. As American attitudes towards immigrants became more negative, the government implemented stricter immigration laws, such as the Immigration Act of 1924. This law placed restrictions on immigration from certain countries and favored immigrants from Western European countries.
