The upper country had no representation in the government and no political existence as a constituent portion of the state until a period near the commencement of the revolution. Indeed, during the revolution, and until the formation of the present constitution, in 1790, its political weight was scarcely felt in the government. Even then although it had become the most populous section, power was so distributed under the constitution as to leave it in a minority in every department of government. Even in 1794 it was claimed by the up-country leaders that four-fifths of the people were governed by one-fifth. Nor was the difficulty met until the constitutional amendment of 1808, the effect of which was to give the control of the senate to the lower section and of the house of representatives to the upper section, thus providing a mutual veto.[117:3] This South Carolina experience furnished the historical basis for Calhoun's argument for nullification, and for the political philosophy underlying his theory of the "concurrent majority."[118:1] This adjustment was effected, however, only after the advance of the black belt toward the interior had assimilated portions of the Piedmont to lowland ideals. When we turn to North Carolina's upper country we find the familiar story, but with a more tragic ending. The local officials owed their selection to the governor and the council whom he appointed. Thus power was all concentrated in the official "ring" of the lowland area. The men of the interior resented the extortionate fees and the poll tax, which bore with unequal weight upon the poor settlers of the back country. This tax had been continued after sufficient funds had been collected to extinguish the debt for which it was originally levied, but venal sheriffs had failed to pay it into the treasury. A report of 1770 showed at least one defaulting sheriff in every county of the province.[118:2] This tax, which was almost the sole tax of the colony, was to be collected in specie, for the warehouse system, by which staples might be accepted, while familiar on the coast, did not apply to the interior. The specie was exceedingly difficult to obtain; in lack of it, the farmer saw the sheriff, who owed his appointment to the dominant lowland planters, sell the lands of the delinquent to his speculative friends. Lawyers and court fees followed.
