Answer:
1. All in all, the period from 1865 through 1914, when immigration was not restricted and steamships were dominant, saw an average yearly immigrant volume of almost 529,000.
2. After a pause in European immigration during the U.S. Civil War, more than 20 million immigrants arrived—primarily from Southern and Eastern Europe—between 1880 and 1920. Most Southern European immigrants were motivated by economic opportunity in the United States, while Eastern Europeans (primarily Jews) fled religious persecution. World War I slowed European immigration, and the national-origin quotas established in 1921 and 1924—which gave priority to Western and Northern Europeans—coupled with the Great Depression and the onset of World War II brought immigration from Europe to a near halt.
