1863: Lawrence, Kansas, is destroyed by Confederate guerrillas Quantrill's Raiders in the Lawrence Massacre. The group targeted Lawrence due to the town's long support of abolition and its reputation as a center for Jayhawkers and Redlegs, which were free-state militia and vigilante groups known for attacking and destroying farms and plantations in Missouri's pro-slavery western counties.
