Which of the following best shows how the issue of states rights contributed to the onset of the civil war? a.)many northerners believed that states rights should not extend to slave states. b.)many southerners believed that giving states additional rights would hold back western expansion. c.)many southerners believed the rights of their states were threatened by northern abolitionist. d.) many southerners believed the rights of their states were threatened by the election of abraham lincoln.

The Civil War broke out between the North and the South primarily because their difference in values. Many southerners were pro-slavery, whereas many northerners were anti-slavery (also known as abolitionists). The decision at hand was whether each state could have their own slavery laws or not. The southerners believed that their "way of life" (which included slavery) would be destroyed if laws were passed that gave the Federal Government control to make nation wide laws, taking the power to allow or ban slavery from the states; they knew the government would abolish slavery, primarily because it consisted of more northerners than southerners. Because of this, many southerners believed the rights of their states were treated by the northern abolitionists in the Federal Government. Hope this helps!
