Between 1877-1914, around 10 million immigrants came to the United States from Europe, many from southeastern Europe like Italy and Eastern Europe. They were drawn by economic opportunities and pushed by factors like overpopulation and crop failures in Europe. Most settled in large cities where cultural communities had already formed and jobs were available. However, native-born Americans began to view the new immigrants more negatively due to fears they were taking jobs and social/political tensions. This led to calls for immigration restrictions and the establishment of groups like the Immigration Restriction League that advocated for literacy tests and quotas to limit immigration.
