Which of the following was a result of the Kansas-Nebraska Act? *

- Fighting broke out between pro-slavery and anti-slavery groups in Kansas
- Nebraskan settlers who supported abolition moved to Kansas
- Kansas entered the Union as a slave state through popular sovereignty in 1856
- The boundary established by the Missouri Compromise of 1820 was extended farther south

All options are correct. As a result of the Kansas-Nebraska Act, fighting broke out between pro-slavery and anti-slavery groups in Kansas; Nebraskan settlers who supported abolition moved to Kansas ; Kansas entered the Union as a slave state through popular sovereignty in 1856 ; and the boundary established by the Missouri Compromise of 1820 was extended farther south.

Explanation:

Kansas-Nebraska law was passed in the United States in 1854 while Franklin Pierce was president.

The law was promoted by Stephen A. Douglas of the Democrats in Illinois, and this made sure that parts of Great Plains territory were organized into two new territories: Kansas Territory and Nebraska Territory. These areas were then opened to settlers, which led to both Kansas and Nebraska getting enough residents to be admitted as states. In line with the idea of ​​the principle of popular sovereignty, the law provided that the inhabitants of these territories could introduce slaveholding if the free population so desired. This thus broke with the Missouri Compromise of 1820, and in effect repealed this.

However, there was a problem when the people's sovereignty was enshrined in the bill, so that those who were voters at this time should vote on whether to allow slavery or not. As a result, both slavery supporters and abolitionists poured into the state to influence voting results, leading to Bleeding Kansas.
