Answer:
Two significant reasons why immigrants came to the United States from Germany between 1820 and 1860 were:
1. **Economic Opportunities:** Many German immigrants sought better economic prospects in the United States. Economic hardships, including poverty and limited job opportunities, drove them to seek employment and land ownership in the expanding American economy. They believed that the United States offered the promise of a better life and the chance to improve their financial well-being.
2. **Political and Religious Freedom:** During this period, political and religious tensions were high in Germany, particularly after the failed revolutions of 1848. Germans seeking greater political freedoms and religious tolerance were attracted to the United States, which was seen as a land of greater political stability and religious diversity. They hoped to escape political oppression and practice their religions freely in America.
