In October 1859, abolitionist John Brown and sympathizers raided the federal arsenal at Harpers Ferry, Virginia (today West Virginia). Tensions in Washington between pro- and anti-slavery forces increased greatly. Johnson gave a major speech in the Senate in December, decrying Northerners who would endanger the Union by seeking to outlaw slavery. The Tennessee senator stated that "all men are created equal" from the Declaration of Independence did not apply to African Americans, since the Constitution of Illinois contained that phrase—and that document barred voting by African Americans. Johnson, by this time, was a wealthy man who owned a few household slaves, 14 slaves, according to the 1860 Federal Census.
