Final answer:
Whites in both the North and South wanted to limit black mobility through a system of "tickets" and "patrols." The system was compatible with the discriminatory practices that were present in both regions during that time period.
Step-by-step explanation:
In the late 1800s and early 1900s, whites in both the North and the South sought to limit black mobility through a system of "tickets" and "patrols." In the North, de facto discrimination and white fears of racial equality led to race riots and the creation of segregated neighborhoods. While legal segregation was more prevalent in the South, the North also had forms of segregation that denied African Americans equal access to education, housing, and employment.
