And it Begins....
THIS IS WAR!
LET THE BLOOD PAINT KANSAS!
To gain support from the South, Douglas agreed to nullify the Missouri Compromise, which led to the to dying of the Democratic party. While the Democratic Party died down, 2 new parties formed: Nativists who disliked the new wave of immigrants and any foreigners, while also hating Catholics.

On May 1856, the town of Lawrence (an antislavery center) was attacked by pro-slavery supporters. In retaliation, abolitionist John Brown, than attacked Pottawatomie Creek (pro-slavery town). Brown slaughtered 5 people, these two events were considered the first blow in the Civil War.
The violence continued, as small armies began to gather were they clashed at Black Jack, Franklin, Fort Sanders,Hickory Point, Slough Creek, and Osawatomie. In September John W. Geary was appointed territorial governor, where he managed to control the border war. This did not stop Kansas though, the "bleeding" continued into 1861.
