Explanation:

Early immigration (1700s–1850): Immigrants from western and northern Europe arrived in great numbers for economic, political, and religious reasons. Germans and Irish, in particular, came to the United States in the 1830s and 1840s. European settlers imported millions of African slaves as well. Most Southern European immigrants were motivated by economic opportunity in the United States, while Eastern Europeans (primarily Jews) fled religious persecution. The United States experienced major waves of immigration during the colonial era, the first part of the 19th century and from the 1880s to 1920. Many immigrants came to America seeking greater economic opportunity, while some, such as the Pilgrims in the early 1600s, arrived in search of religious freedom.
