The civil right movement was a social movement in the United State to end racial segregation and discrimination against African-Americans and to secure legal recognition and federal protection of the citizenship rights enumerated in the Constitution and federal law. Racial caste is a way people use to put different color people into different social levels. The ones who are in lower social level, who are the African Americans, are being treated unequally by other people. The existence of racial caste is going to leave a mark in people’s mind, when they think about black people then the word “dangerous”, “prisoner” is gonna come up. Most of the black prisoners don’t get caught because of doing illegal stuff, but because of their skin color, because of their race. That is one of the most important reasons for the build of the form of mass incarceration.
