Answer:
Racial Violence
Step-by-step explanation:
Given that there were no options in the question, the factor that played the GREATEST role in the movement of the Exodusters is RACIAL VIOLENCE.
This is evident in the fact that White Supremacists like KK Clan were constantly attacking the black community at the time.
Similarly, the Black codes that were used to governing the affairs of the black community were considered as suppressing and discriminatory.
Exodusters is the massive movement of the Black community from southern states around the Mississippi River to Kansas, Oklahoma, and Colorado. It was in the late nineteenth century, particularly in 1879.
