History of Europe

What European immigrants came during the Civil War?

The correct answer is Irish.

The Irish were the largest European immigrant group to arrive in the United States during the Civil War. Between 1860 and 1870, over 1 million Irish people immigrated to the United States. The Irish were fleeing the Great Famine, which was a period of severe food shortages and disease in Ireland that lasted from 1845 to 1852. The Irish were also drawn to the United States by the opportunity for jobs and land ownership.
