The events leading up to 1856 raid on Lawrence began with the opening of the Kansas Territory to settlement with the Kansas-Nebraska Act of 1854. David Potter in his book The Impending Crisis, 1848-1861 posits that William H. Seward, in a speech to the Senate on May 25, 1854, issued a challenge to pro-slavery supporters effectively sparking a competition to see which side, pro-slavery or free-state, could populate Kansas the fastest and thus gain its control.
“’Come on then, Gentlemen of the Slave States,’ he said, ‘since there is no escaping your challenge, I accept it on behalf of the cause of freedom. We will engage in competition for the virgin soil of Kansas, and God give the victory to the side which is stronger in numbers as it is in right.’ This act transplanted the controversy from the halls of Congress to the plains of Kansas.”
