What was the Kansas-Nebraska act?
The act established that settlers could vote to decide whether to allow slavery, in the name of “popular sovereignty” or rule of the people. Douglas hoped it would ease relations in both North and South, because the South could expand slavery to new territories but the North still had the right to abolish slavery in their states. He was wrong. Opponents denounced the law as a concession to the slave power of the South. The new Republican Party, which was created in opposition to the act, aimed to stop the expansion of slavery, and soon emerged as the dominant force throughout the North.
