Which territories were affected by the compromise of 1850 and how?

The Missouri Compromise of 1850 affected Kansas & Nebraska territories. The Compromise was an extension of the one made in 1820. The idea behind the compromises was to maintain the balance of free states and slave states.

Now the statehood of Kansas & Nebraska came into the mix.

The consensus of Congress was that left to themselves, the people of Kansas would follow the lead of Missouri and vote to become a slave state. Also, that the people of Nebraska would vote for a "free state".

Later events, such as a major conflict in Kansas & the soon to come Civil War would send the compromises into a free fall.
