Can someone please help me While the Civil War is the most important development of the 1840s to the 1860s, immigration is also a principal theme of this period. We have seen that the Irish, Germans, and Jews were influential groups that immigrated to the United States during this period. However, the Chinese were also a major group that came to the United States before the Civil War, and their immigration continued after the war. Research their immigration, and write a short essay covering the reasons for their immigration, their lives here, and why they became important in the United States. After you have completed this project, have your teacher score your essay.

i mainly just need the reasons for their immigration, their lives here, and why they became important in the United States. i just need the facts
