When the immigrants first start to coming to the US?

Immigration to the United States began in significant numbers in the early 19th century, with large waves arriving during the 1820s and 1830s, primarily from Europe. The 1840s and 1850s saw a dramatic increase, driven by factors like the Irish Potato Famine and political unrest in Germany. This trend continued through the late 19th and early 20th centuries, with millions seeking better opportunities and refuge from hardships in their home countries. The immigration landscape has evolved over time, reflecting changing policies and global circumstances.
