New Immigrants Help a Nation Grow
This Grade 5 history skill in IMPACT California Social Studies explains how new waves of immigrants from Europe, especially Ireland, helped the young United States grow in the mid-1800s. Students learn that a potato blight caused the Great Famine of 1845 to 1852 in Ireland, a period of mass starvation that killed approximately one million people and drove another million to sail to America. Irish immigrants took difficult jobs that built the nation, including digging the Erie Canal, connecting regions and fueling the industrializing economy of the young republic.
Key Concepts

Common Questions
What caused so many Irish people to immigrate to the United States in the mid-1800s?
A plant disease destroyed Ireland potato crops, which was the main food for millions of poor Irish people. This triggered the Great Famine from 1845 to 1852, a period of mass starvation. About one million Irish people died and another million emigrated to survive, with many sailing to America.
What was the Great Famine?
The Great Famine was a catastrophic period in Ireland from 1845 to 1852 when a potato blight wiped out the potato harvest. Since potatoes were the staple food for much of the poor population, the crop failure caused widespread starvation and forced massive emigration.
What kinds of jobs did Irish immigrants take in the United States?
Irish immigrants often took the most difficult and dangerous jobs available. Many worked on large construction projects, including digging the Erie Canal, which connected the Hudson River to the Great Lakes and helped link different parts of the growing nation.
What was the Erie Canal and why was it important?
The Erie Canal was a 363-mile waterway in New York State connecting the Hudson River to Lake Erie. Completed in 1825, it dramatically reduced the cost and time of shipping goods between the East Coast and the interior of the country, fueling economic growth.
How did immigration change the population of the United States in the mid-1800s?
Immigration from Ireland, Germany, and other European countries dramatically increased the U.S. population. Cities like New York, Boston, and Chicago grew rapidly as immigrants settled there, creating diverse urban communities and a larger labor force for industrialization.
Did all Americans welcome the new immigrants?
No. Many native-born Americans resented the new arrivals, especially the Irish Catholics. Anti-immigrant sentiment was widespread, with some groups fearing competition for jobs and others holding religious prejudices. Despite this hostility, immigrants continued to come and contribute to building the nation.
