Slavery throughout the US was permanently astablished by what?

Slavery in the United States was permanently established by the legal framework created through various colonial laws and the Constitution, particularly the Three-Fifths Compromise and the Fugitive Slave Act. The institution was further entrenched by the Supreme Court's Dred Scott decision in 1857, which ruled that enslaved individuals were not citizens and had no rights. Additionally, economic interests in the southern states, reliant on slave labor for agriculture, solidified slavery's permanence until the Civil War.
