Question

What sparked Irish immigration to the United States in the mid-1840s?

Answer 1

Jobs in the Ellis Island

Answer 2

The answer is "famine".

In the mid-1840s, the potato crops, which were the base of the Irish people diets, were distroyed by a blight, a plant disease.

The hunger forced people to emigrate, mainly to North America. They had no skills, no money, few belongings and most had no education.
