Explanation:

In American history, the Kansas-Nebraska Act of 1854 allowed people in Kansas and Nebraska to decide if they would allow slavery within their borders, in other words, it gave people from these states  sovereignty regarding slavery. Let's take in mind that back in the day, slavery was forbidden in most states. This Act ultimately led to confrontations among pro-slavery people and people who opposed slavery.

Therefore, the Kansas-Nebraska Act of 1854 established the principle of popular sovereignty whereby the status of slavery would be determined.
