Immigrants from the population of Italy started late. At the end of the nineteenth century the Italians fell behind immigrants in Ireland, Germany and France (Nelli 38) with a major period of immigration. This turned out to be harmful for the Italians, the previous immigrants sew themselves on the flag and have a firm hatred for the immigrants coming, one of them It is Salvatore Rossi. Due to economic difficulties, he ran away from Italy in 1897. He pursued "American Dream" in New York, was educated in the United States, landed an unusual work.
Since 1890, Italian immigrants to the United States became part of the third largest immigrant in Europe, the so-called "new immigrants" composed of Slavs, Jews, Italians. This "new immigrant" is a major change from the "old immigrants" including German, Irish, British, Scandinavian and occurred through the 19th century. Between 1900 and 1915, three million Italians migrated to the United States. This is the largest nationality of "new immigrants". These immigrants, principally craftsmen and farmers, represent all the regions of Italy, but they originate mainly from Mezzojorno in Southern Italy. Between 1876 and 1930, 4 out of 5 million immigrants from the United States came from the south, representing Calabria, Campania, Abruzzo, Molise and Sicily. Almost (2/3 of immigrant population) is agricultural workers or workers, or contadini.
Immigrants from South and Eastern Europe, including immigrants from Italy, are considered suspicious populations. Since 1880, Italian immigrants have flooded the country. Between 1900 and 1920, three million Italians migrated to the United States. Most are unskilled semi-skilled workers, others join a group specializing in social revolution and overwhelming capitalist systems. Postwar events caused a red panic, a period of panic about communist and anarchist threats. There was a wave of large strikes in this country. In the year after the war, 4 million workers strike in 1919. The Communist Revolution took place in Russia in 1917, and many Americans feared that a similar revolution will occur in the United States. The American anarchist group strongly opposed the war began a series of terrorist acts after the war. In April 1919, the postal bomb was sent to famous politicians and wealthy and powerful businessmen.
