In “The Fatal Environment”, historian Richard Slotkin demonstrates how the myth of frontier expansion and subjugation of Native Americans helped justify the course of America's rise to wealth and power. Using Custer's Last Stand as a metaphor for what Americans feared might happen if the frontier should be closed and the "savage" element be permitted to dominate the "civilized," Slotkin shows the emergence by 1890 of a mythos redefined to help Americans respond to the confusion and strife of industrialization and imperial expansion.
