African American settlers traveling westward responded to the racism they faced from white settlers by protesting and starting a cultural renaissance.
Over six million African Americans moved out of the rural Southern United States and migrated to the urban Northeast, Midwest, and West in what is called the Great Migration (1910-1970).
The reasons included the poor economic conditions of African Americans in the Southern states, the continuation of racial segregation and discrimination there including the widespread lynchings of blacks.
These migrants settled in the largest cities like New York, Chicago, and Los Angeles, forming influential communities in these places.
Due to these large-scale migrations, competition for jobs and housing rose, and this caused tensions with the white settlers there. White workers in various factories demanded segregation in the workplace, which erupted in violence.
African American settlers responded through labor activism and protests, and most significantly it led to the Harlem Renaissance in the 1940s, which was an African-American cultural revolution.
