On the south along the Gulf Plains there developed the "Cotton Kingdom," a Greater South with a radical program of slavery expansion mapped out by bold and aggressive leaders. Already this Southern section had attempted to establish increasing commercial relations with the Ohio Valley. The staple-producing region was a principal consumer of its live stock and food products. South Carolina leaders like Calhoun tried to bind the Ohio to the chariot of the South by the Cincinnati and Charleston Railroad, designed to make an outlet for the Ohio Valley products to the southeast. Georgia in her turn was a rival of South Carolina in plans to drain this commerce itself. In all of these plans to connect the Ohio Valley commercially with the South, the political object was quite as prominent as the commercial. In short, various areas were bidding for the support of the zone of population along the Ohio River. The Ohio Valley recognized its old relationship to the South, but its people were by no means champions of slavery. In the southern portion of the States north of the Ohio where indented servitude for many years opened a way to a system of semi-slavery, there were divided counsels. Kentucky also spoke with no certain voice. As a result, it is in these regions that we find the stronghold of the compromising movement in the slavery struggle. Kentucky furnished Abraham Lincoln to Illinois, and Jefferson Davis to Mississippi, and was in reality the very center of the region of adjustment between these rival interests. Senator Thomas, of southern Illinois, moved the Missouri Compromise, and Henry Clay was the most effective champion of that compromise, as he was the architect of the Compromise of 1850. The Crittenden compromise proposals on the eve of the Civil War came also from Kentucky and represent the persistence of the spirit of Henry Clay. In a word, as I pointed out in the beginning, the Ohio Valley was a Middle Region with a strong national allegiance, striving to hold apart with either hand the sectional combatants in this struggle. In the cautious development of his policy of emancipation, we may see the profound influence of the Ohio Valley upon Abraham Lincoln--Kentucky's greatest son. No one can understand his presidency without proper appreciation of the deep influence of the Ohio Valley, its ideals and its prejudices upon America's original contribution to the great men of the world.
