"From the moment that Monroe adopted as his guiding principle the maxim that he was head of a nation, not the leader of a party, he repudiated for all practical purposes the party unity" that would have served to establish his policies. The result was a loss of party discipline. Absent was the universal adherence to the precepts of Jeffersonianism: state sovereignty, strict construction and stability of Southern institutions. Old Republican critics of the new nationalism, among them John Randolph of Roanoke, Virginia, had warned that the abandonment of the Jeffersonian scheme of Southern preeminence would provoke a sectional conflict, North and South, that would threaten the union. Former president James Madison had cautioned Monroe that in any free government, it was natural that party identity would take shape.
