Many timelines have wondered what would have happened if slavery had been made illegal in the US constitution, or if a date for abolition had been set. I would like to ask what would have happened if manumission, the voluntary freeing of a slave by the master, had been constitutionally protected, so that no state could interfere with the right of a slave-owner to free his own slaves, along with abolishing the slave trade in 1807. Would this have been especially difficult to achieve at the convention? I propose this addition to the original constitution because southern states would outlaw manumission in order to maintain the institution of slavery, as there was a fear that all the slaves soon could be freed, and such a clause in the constitution seemingly could have a big result down the road.
