The black community suffered from physical attacks, institutional segregation, and discrimination by the legal system. Alongside these outrageous conditions, a growing expression of white supremacy started to become the norm. Not only African-Americans suffered the consequences, as <u>the chinese community was also impacted by the same kind of violence</u> and institutionalized racism, culminating in the Chinese Exclusion Act of 1882.
