How did the context of the civil war impact opinions about immigration during the civil war?

Explanation: Despite the prejudice and violence, immigration increased more than 500 percent from 1845 until 1855, with about three million immigrants coming to the United States. Almost 90 percent settled in the North or the West, where either jobs or cheap land or both, were plentiful. German and Hungarian farmers tended to settle in the central and upper Midwest. By 1860, more than 1.25 million Americans of German descent lived in the United States.

Unskilled and semiskilled immigrants from Ireland, Wales, and Italy settled in urban or industrialized areas in Pennsylvania, New York, and New England. These immigrants, particularly the Irish, often found themselves competing against native-born white Americans and free blacks for low paying jobs. The million Irish immigrants who came to America were survivors of the Great Irish Famine (1845-1852) and could be both tenacious and incredibly brutal, as events in 1862-1863 would show.
