Answer:
In the late 19th century, many Europeans and Chinese immigrants moved to the United States, where they helped to drive the growth of cities and industrialization. However, many Americans did not welcome these immigrants, and some legislators tried to limit their numbers. Despite some Supreme Court decisions protecting the rights of immigrants, many were still treated as second-class citizens. At the same time, the US was undergoing rapid urbanization and technological advancements. This period of history was marked by a lot of change and upheaval, including racial profiling of immigrants.
