Problem: The Fourteenth Amendment established the concept of birth right citizenship, but fairly quickly after its ratification African-Americans, Asian Americans, Native Americans, and Mexican-Americans found themselves either second-class citizens or denied citizenship completely. Consider the factors that were used to deny or limit non-white citizenship and the arguments made against these groups. Who fought back against these challenges? What were their arguments? Did they make any headway in the late 19th Century? Cite specific people, decisions, and acts.
