The Unconstitutionality of Slavery

The Unconstitutionality of Slavery is an 1845 abolitionist essay by Lysander Spooner that argues against the legality of slavery in the United States. Spooner contends that slavery contradicts the principles of natural rights and the Constitution, asserting that laws permitting slavery are inherently invalid. He critiques the judicial system for failing to uphold natural law and emphasizes that the Constitution guarantees individual rights, making slavery unconstitutional. This work significantly influenced the abolitionist movement and shaped legal arguments against slavery in America.
