Final answer:
The fate of the slaves would have depended on whether the state had abolished slavery or not.
Step-by-step explanation:
If a state had returned, the fate of the slaves would have depended on whether the state had abolished slavery or not. During the American Revolution, the question of whether slavery should continue to exist was raised, as the idea of liberty and equality clashed with the institution of slavery. Some northern states embraced gradual emancipation during and after the war, while most southern states maintained and even strengthened their commitment to slavery. Therefore, if a state that had seceded from the Union had returned, it is likely that the slaves in that state would have remained in bondage.
