“It is the eternal struggle between these two principles — right and wrong — throughout the world. They are the two principles that have stood face to face from the beginning of time; and will ever continue to struggle. The one is the common right of humanity, and the other the divine right of kings. It is the same principle in whatever shape it develops itself. It is the same spirit that says, "You toil and work and earn bread, and I'll eat it." No matter in what shape it comes, whether from the mouth of a king who seeks to bestride the people of his own nation and live by the fruit of their labor, or from one race of men as an apology for enslaving another race, it is the same tyrannical principle.”

He was a significant force behind the Compromise of 1850 and the Kansas-Nebraska Act; both which included the idea of "popular sovereignty." Douglas was a strong believer in this doctrine, which said that the people of the territories should choose whether they wanted slavery or not. On the other side was Abraham Lincoln; a Republican who was unknown nationally until these debates. Lincoln was opposed to the expansion of slavery; he believed it should be restricted and not permitted in the new territories. He felt slavery was morally incorrect, and in his "house-divided" speech explained that the union could not survive forever as half free and half slave. Lincoln hoped for a nation without slavery eventually. Their clear, clashing viewpoints on slavery caused it to be the main issue throughout the debates. The debates took place between August and October, 1858, in seven different cities in Illinois: Ottawa, Freeport, Jonesboro, Charleston, Galesburg, Quincy, and Alton.
