"The myth of the Frontier is our oldest and most characteristic myth, expressed in a body of literature, folklore, ritual, historiography, and polemics produced over a period of three centuries. According to this myth-historiography, the conquest of the wilderness and the subjugation or displacement of the Native Americans who originally inhabited it have been the means to our achievement of a national identity, a democratic polity, an over-expanding economy and a phenomenally dynamic and 'progressive' civilization."

Richard Slotkin, Gunfighter Nation
