Why did slavery continue to exist during and after the revolution

Explanation:                                                                                                                The American Revolution generated unprecedented debates about morality of slavery and its compatibility with the founding creeds of the new nation. Though the Revolution did not lead to abolition of slavery, it set off a process of both immediate and gradual emancipation in northern states. The South’s slave system suffered because of the war, which resulted in a decline in production and a loss of thousands of slaves to the British. Though a small number of slaveholders, particularly in Virginia, emancipated their slaves after the Revolution, slavery remained entrenched in the southern states and would only become more profitable and spread further to the west and south during the late eighteenth and into the nineteenth century.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.

in 1965, president johnson signed the voting rights act, which aimed to overcome legal barriers that prevented african americans from voting as it was guaranteed by the 15th amendment to the u.s. constitution.
