How did migration to the United States change popular ideas of American identity and citizenship as well as regional and racial identities? How did the conflicts that lead to civil war change popular ideas about national, regional, and racial identities throughout this period?

Migration created a mixture of ideas and beliefs that lead to developing a new idea about patriotism and citizenship. However, conflicts in such a diverse society are common, and because of that, conceptions such as segregation, and laws against mixture began to be created. A good example is the separation of North-South and the Jim Crow Laws that marked people's relationships during the 20th century.

Explanation:

Migration to the United States changed popular ideas of American identity and citizenship by mixing a multitude of cultural beliefs with a strong sense of nationality and patriotism leading to a powerful mixture of ideas and opinions about government. The growing tensions mounting towards physical unrest began to alter this delicate mixture of believes across the north south divide affecting all aspects of American views such as the believe of both northern and southern politicians that the other side was attempting to oppress the other with their views on slavery and the human conditions.
