This new law arose from the tensions between southern slave states and northern “free states.” Although Africans held in slavery would still not be considered citizens nor be allowed to vote, southern states wanted slaves to be considered persons to increase the representation of the south in the House of Representatives. Northern states, however, wanted to prevent the South from gaining political power. The compromise demonstrated the force of pro-slavery Southerners and maintained slavery. Even after the slave trade was outlawed in 1808, Southern states continued to increase their political power by forcing enslaved people to have children.
