The Framers never directly ended the practice of slavery. The Constitution actually never uses the words slavery, slaves, or slave trade. The framers do end the slave trade. Those abolitionists had hoped, that by no longer allowing slaves to enter into the country, that this would effectively shorten the life of the slave trade and eventually kill it. However, it never addressed anything in regards to slaves born in the country. This "loophole" would allow slavery to continue for the next hundred years and lead to thousands being born into the institution of slavery.
