What allowed the slave states to count their slave as part of the population when paying taxes and electing representitives?

The Three-Fifths Compromise, established in 1787 during the Constitutional Convention, allowed slave states to count each enslaved person as three-fifths of a person for the purposes of taxation and representation. This compromise was a political solution to balance the interests of slaveholding states with those of free states, ultimately influencing congressional representation and the allocation of taxes. It reflected the contentious nature of slavery in the United States and highlighted the unequal status of enslaved individuals in the political system.
