The repeal of the Missouri Compromised affected Kansas allowed citizens of Kansas to vote on whether or not slavery would exist in their state.
Further Explanation:
The Missouri Compromise (1820) was an extremely important law in America during the 1800's. This law established where slavery would and would not exist in the United States for over three decades. As America was expanding westward during this time, the issue of whether or not slavery would exist in these new territories needed to be solved.
In this case, the Missouri Compromise established the idea that all territories north of 36'30 (aka Missouri's southern border) would NOT have slavery. This meant that any territory added to the United States south of this border WOULD allow slavery.
The Missouri Compromise would ultimately be repealed due to the Mexican Cession. When this was repealed, Congress had to figure out a new way to decide on the issue of slavery in new states.
To solve this issue in Kansas, Congress created the Kansas Nebraska Act. The Kansas Nebraska Act allowed for the idea of popular sovereignty to be used. This essentially allowed citizens to vote on whether or not slavery would exist in their state. This law worked horribly and lead to a violent period known as "Bleeding Kansas." Bleeding Kansas and the fight over slavery would be one of the many causes of the US Civil War.
