Final answer:
A correlation existed between former Confederate states and civil rights disturbances, with African Americans facing discrimination in the South leading to the Great Migration North, where they still encountered de facto discrimination and sometimes violent resistance.
Step-by-step explanation:
There was indeed a correlation between the former Confederate states and the locations where civil rights disturbances occurred. After the Civil War, African Americans faced intense racial hatred and violence, including the rise of the Ku Klux Klan and a wave of lynchings, prompting a migration towards the North and Midwest.
Despite this move, de facto discrimination persisted; for example, race riots erupted in Springfield, Illinois, when the local authorities refused to release a black prisoner to a white mob.
Civil rights activism was not limited to the South, nor was it exclusive to the 1950s and 1960s, as evidenced by the civil rights cases involving a range of public facilities in the early 1900s.
In the mid-20th century, during World War II and after, African Americans continued to fight against discrimination, resulting in incidents like the Detroit and Harlem riots, and race-based violence near military bases in the South. African American leaders worked to improve conditions, laying groundwork for the later civil rights movement.
The struggle was more intense in the Deep South states like Mississippi, Alabama, and Georgia, where resistance to integration was fierce compared to the Border South states such as Missouri and West Virginia.
