Final answer:
In the 1890s, most U.S. immigrants came from southern and eastern Europe, including Italy, Greece, Russia, and various Slavic nations, which contrasted previous immigration patterns from northern and western Europe.
Step-by-step explanation:
In the 1890s, immigration patterns shifted dramatically, with most immigrants to the United States coming from southern and eastern Europe. This included many peasant farmers, individuals fleeing religious persecution, particularly Jewish people from the Russian Empire, and those displaced by the effects of industrialization. Countries such as Italy, Greece, Russia, and various Slavic nations saw vast numbers of their citizens emigrating to the U.S. These new immigrants were in contrast to previous waves from northern and western Europe and often settled in urban areas to work in the growing manufacturing sector.
