The conquest of the West is usually attributed to the ready initiative, the stern self-reliance, and the libertarian instinct of the expert backwoodsmen. These bold, nomadic spirits were animated by an unquenchable desire to plunge into the wilderness in search of an El Dorado at the outer verge of civilization, free of taxation, quit-rents, and the law's restraint. They longed to build homes for themselves and their descendants in a limitless, free domain; or else to fare deeper and deeper into the trackless forests in search of adventure. Yet one must not overlook the fact that behind Boone and pioneers of his stamp were men of conspicuous civil and military genius, constructive in purpose and creative in imagination, who devoted their best gifts to actual conquest and colonization. These men of large intellectual mold--themselves surveyors, hunters, and pioneers--were inspired with the larger vision of the expansionist. Whether colonizers, soldiers, or speculators on the grand scale, they sought to open at one great stroke the vast trans-Alleghany regions as a peaceful abode for mankind. Two distinct classes of society were gradually drawing apart from each other in North Carolina and later in Virginia--the pioneer democracy of the back country and the upland, and the planter aristocracy of the lowland and the tide-water region. From the frontier came the pioneer explorers whose individual enterprise and initiative were such potent factors in the exploitation of the wilderness. From the border counties still in contact with the East came a number of leaders. Thus in the heart of the Old Southwest the two determinative principles already referred to, the inquisitive and the acquisitive instincts, found a fortunate conjunction. The exploratory passion of the pioneer, directed in the interest of commercial enterprise, prepared the way for the great westward migration. The warlike disposition of the hardy backwoodsman, controlled by the exercise of military strategy, accomplished the conquest of the trans-Alleghany country.
