In Illinois, Missouri, and throughout the South the demand was well-nigh unanimous that the disputed region along the Rio Grande should be held as against Mexico, and that California and Oregon should be seized and colonized. Cass, the older, and Douglas, the younger leader of the Northwest, were agreed in these extreme demands; even Benton, the disappointed friend of Van Buren, found compensation in the proposed Pacific frontier, while a powerful group of Southerners led by Governor Gilmer, of Virginia, Robert Barnwell Rhett, of South Carolina, William L. Yancey, of Alabama, and Jefferson Davis, of Mississippi, took up the program of Calhoun and pressed it almost daily upon Congress and the country. The South was about to resume control of the national fortunes.
In that region, where cotton was king, and tobacco, sugar, and rice were powerful allies, a unique civilization had grown up. The plantation was the model, and the patriarchal master of slaves the ideal character which the ambitious poor imitated everywhere. The elegant life of the colonial plantation houses, which adorned the banks of the winding rivers of the old South in the days of the Revolution, had gradually moved westward and southwestward until the larger tobacco area of the Piedmont region extended from Petersburg, Virginia, to Greensboro, North Carolina, and from the falls of the rivers to the slopes of the Blue Ridge. Instead of running away from their slaves, as John Randolph had feared Southern gentlemen would be compelled to do, the tobacco planters found their business increasingly prosperous as the great cotton area south of them opened larger markets for their crops and higher prices for their surplus negroes. Even the wheat-growers of Virginia and Maryland became again prosperous when the great canals and the improved turnpikes reached the valley of Virginia and opened still wider areas of rich lands to the Richmond and Baltimore markets. The plantation form of life penetrated the high lands of Virginia almost to the Tennessee border, and slavery was fastening its hold upon the up-country people who had formerly been hostile.
But the vast cotton region, embracing the better part of middle and eastern North Carolina and the accessible lands of the lower South to Eastern Texas, and extending over most of the Mississippi Valley to St. Louis, was the heart of the South, which supported the Polk Administration and waged the war upon Mexico soon to begin. In this fine country, men of ability made fortunes in a few years and learned to imitate the life of the old southern manor houses. Forests were cleared away in winter by the sturdy hands of slaves, and new fields were opened to cotton culture each spring to supply the places of those that had been rapidly worn down by unscientific methods of agriculture. The cabins which made the homes of well-to-do men in the Jeffersonian epoch gave way to substantial frame houses with massive columns and wide verandas, with great hallways and broad banquet-rooms, which so much delighted the heart of the planter of Calhoun's day. In a warm climate like that of the cotton region the object of the builder was always to attain cool recesses and retired gardens, where the social life of the time displayed itself.
