In the decades leading up to the Civil War, the Southern states experienced extraordinary change that would define the region and its role in American history for decades, even centuries, to come. Between the 1830s and the beginning of the Civil War in 1861, the American South expanded its wealth and population and became an integral part of an increasingly global economy. It did not, as previous generations of histories have told, sit back on its cultural and social traditions and insulate itself from an expanding system of communication, trade, and production that connected Europe and Asia to the Americas. Quite the opposite, the South actively engaged new technologies and trade routes while also seeking to assimilate and upgrade its most “traditional” and culturally engrained practices—such as slavery and agricultural production—within a modernizing world.
Beginning in the 1830s, merchants from the Northeast, Europe, Canada, Mexico, and the Caribbean flocked to Southern cities, setting up trading firms, warehouses, ports, and markets. As a result, these cities—like Richmond, Charleston, St. Louis, Mobile, Savannah, and New Orleans, to name a few—doubled, and even tripled, in size and global importance. Populations became more cosmopolitan, more educated, and wealthier. Systems of class—lower-, middle-, and upper-class communities—developed where they had never clearly existed. Ports that had once focused entirely on the importation of slaves, and shipped only regionally, became homes to daily and weekly shipping lines to New York City, Liverpool, Manchester, Le Havre, and Lisbon. The world was, slowly but surely, coming closer together; and the South was right in the middle. Chapter 11 from American Yawp
John Louis O’Sullivan, a popular editor and columnist, articulated the long-standing American belief in the God-given mission of the United States to lead the world in the peaceful transition to democracy. In a little-read essay printed in The United States Magazine and Democratic Review, O’Sullivan outlined the importance of annexing Texas to the United States:
Why, were other reasoning wanting, in favor of now elevating this question of the reception of Texas into the Union, out of the lower region of our past party dissensions, up to its proper level of a high and broad nationality, it surely is to be found, found abundantly, in the manner in which other nations have undertaken to intrude themselves into it, between us and the proper parties to the case, in a spirit of hostile interference against us, for the avowed object of thwarting our policy and hampering our power, limiting our greatness and checking the fulfillment of our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions. John Louis O’Sullivan ((John O’Sullivan, “Annexation,” United States Magazine and Democratic Review 17, no.1 (July-August 1845), 5-10.))
O’Sullivan and many others viewed expansion, particularly to the West, as necessary to achieve America’s destiny and protect American interests. The antebellum period saw the quasi-religious call to spread democracy coupled with the reality of thousands of settlers pressing westward. The precepts of manifest destiny, grounded in the twin beliefs of virtuous American institutionalism and the uplifting effects of agrarian republicanism, rode the wagon trails westward in advance of the "destinarian" belief in American greatness – the proverbial city on the hill of the colonial period began its move westward.
