King Cotton fueled the rapid expansion of slavery into new territories and the forcible relocation of African Americans to the Deep South. Yet as slavery intensified, so did resistance. From individual acts to mass rebellions, African Americans demonstrated their determination to undermine and ultimately eradicate slavery.
