Fugitive Slave Act Signed into Law
Sectional tensions over slavery intensified in the United States after the Mexican-American War added new territories. The Compromise of 1850 sought to balance free and slave state interests through multiple bills. On September 18, 1850, President Millard Fillmore signed the Fugitive Slave Act, strengthening the 1793 law by requiring citizens to assist in capturing escaped enslaved people and denying fugitives jury trials or testimony rights. Federal commissioners received fees for rulings favoring claimants, while penalties applied to those aiding escapes. The measure aimed to appease Southern interests but provoked widespread Northern resistance.
Why it matters: The Act inflamed abolitionist sentiment and Underground Railroad activity, contributing directly to the polarization that led to the Civil War. It exposed the fragility of the Compromise of 1850 and radicalized public opinion in free states through cases like the Anthony Burns affair. Long-term, it highlighted the moral and legal contradictions of slavery, influencing later Reconstruction amendments and civil rights struggles.
