The events in Lawrence that led to John Brown's actions: a pro-slavery marshall assembled a posse to arrest free-state leaders to promote slavery
SLAVERY IS GOOD!
As a result, John Brown, a radical abolitionist, joined with 6 followers to make Kansas a free state. He became the symbol of "Bleeding Kansas" and the sectional controversy.
Brown and his followers (including his kids) murdered 5 pro-slavery settlers. This was known as the Pottawatomie Massacre. There was no resolution to this issue, like many other conflicts within chaos of the early state of Kansas.
This event led to civil strife in Kansas including armed bands engaging in guerrilla warfare The people involved in the resulting warfare were often also interested in land or loot The results of John Brown’s actions in Kansas were the outlook of the aggressive design of the rival section; essentially the symbol “Bleeding Kansas” represented the sectional controversy HIs actions promoted tension in Kansas as the dispute elevated to murder as seen through Brown’s actions
Through the additions of new states such as Kansas and deciding whether those states should be entered as free or slave states, the tension continued to grow between the Northern and Southern states.
