Answer:
The Kansas-Nebraska Law was passed in 1854. This law had the objective of creating two new states, Kansas and Nebraska, which would define their acceptance or not of slavery through popular sovereignty, in which the people would vote by accepting it or not. This situation clearly violated what was established in the Missouri Compromise, since both territories were north of the 36º 30 'parallel, established by said commitment as the limit between the slave states and the free states.
This situation, which protected the possibility of popularly deciding on slavery, intensified the conflict between slavers and abolitionists, since both groups were allowed to take a direct part in the establishment or not of slavery in those territories. Thus, when thousands of representatives of both groups moved to Kansas to participate in the voting, a situation of confrontation and violence between the two was generated, which became known as Bleeding Kansas.
