In the court case, Ableman versus Booth, the U.S. Supreme Court rules that the 1850 Fugitive Slave Law is constitutional and that state courts cannot overrule federal court decisions. On October 16, Kansas abolitionist John Brown attempts to spark a slave rebellion in Virginia by capturing weapons from the federal armory at Harper’s Ferry, Virginia. Brown holds the arsenal building for 36 hours. No slaves joined him and no rebellion starts, but 17 people, including 10 of Brown’s men, are killed. Brown and his remaining men are captured by the U.S. Marines led by Army Lieutenant Colonel Robert E. Lee. Brown is tried for treason to the state of Virginia, murder and calling for a slave uprising. He was found guilty of all charges and hanged on December 2, 1859.
