Famine and political upheaval in Europe drove millions of Irish and German immigrants to America in the mid-nineteenth century.
- Germans and Irish were the two main groups of immigrants to the United States from the 1820s to the 1840s. Anti-foreign prejudice and discrimination were common towards Germans and Irish.
- Eventually, the Germans and Irish adapted into American culture and society, becoming two of the country's most successful immigrant groups.
- In the 1830s, the number increased to 235,000, and in the 1840s, due to a potato famine in Ireland, the number increased to 845,000. Germans were the second largest group of immigrants to the United States after the Irish from the 1820s to the 1840s. They migrated to the United States in search of greater political and religious freedom as well as economic opportunity than they could find in Europe.
Thus this is what drove migrations of Germans and scots-Irish into the colonies.
