The struggle between the two ideals carried the greatest weight in the newly settle territories just east of the frontier. Ultimately, the outcome of the clash of the two myths and the models they put forth would become the conflict between the free and slave states. The failure of the Southern system to prevail can be traced to the failure of its hold on the states forming in the Midwest. While literature and public papers of the time offer examples of both Jeffersonian agrarianism and apologism for slavery, Smith blames the weakness of the plantation myth for the decline of the institution. He writes "pro-slavery advocates of annexation failed entirely to create symbols comparable to the free-soil symbol of the yoeman. They were prepared to defend slavery as such with the standard doctrines, and to state of familiar propositions of manifest destiny, but they were not able to endow the westward expansion of the slave system with imaginative color"(VL,152.)
