I want to know the answer to the following question:
How many major riots between blacks and whites occurred in Charleston in 1876?
All the background I'm provided with is that "With leadership by members of the antebellum free black community, historian Melinda Meeks Hennessy described the community as "unique" in being able to defend themselves without provoking "massive white retaliation", as occurred in numerous other areas during Reconstruction.". Is that enough to answer the question?
