Crime and violence in Chicago More specific: Crime and violence in racial prejudice of Chicago, 1875-1920 Research question(s): Between 1875 and 1920, what are the causes of crime and violence in Chicago, and what is the impact? Thesis statement: Between 1875 and 1920, the violent and crime rate rose sharply in Chicago. This phenomenon is due to people's prejudice against race, which is closely related to the political environment of the government, people's religious beliefs and historical factors. Supporting idea: 1. The political environment of Chicago's government is influenced by the Democratic Party, which segregates citizens of different races, leading to prejudice against other races, thus triggering social violence and crime. 2. Different religious beliefs reflect the differences in perception and cognition among different ethnic groups. 3. Chicago's social environment of racial inequality has contributed to the inducement of local violence and crime and has increased the incidence of violence and crime among different ethnic groups in Chicago.
