What are some US immigration events in 1850-1900?

please list 3

In the span of about 50 years, there were about 20 major and minor population migrations.

Explanation:

In the second half of the nineteenth century until the beginning of the 20th century, over 12 million migrants immigrated to the United States. The reasons were mostly economic in nature but also religious.

In 1860, a large number of Poles and Russians came for the aforementioned reason. These two national groups' continuous settlement can be followed until 1914 when about 2 million Poles and Russians immigrated.

In this context, we will also mention one event that caused population movements in the United States. In 1863, the Union banned slavery and allowed African Americans to join the military, causing large-scale migrations of the African-American population to the north.

Around 1880, primarily due to Italy's poor economic situation, a huge number of Italians immigrated to the united states. Since then, more intensive settlement of Italians in the unification of the state has begun.
