Reviewed by: The End of the Myth: From the Frontier to the Border Wall in the Mind of America by Greg Grandin Mark A. Goldberg The End of the Myth: From the Frontier to the Border Wall in the Mind of America. By Greg Grandin. (New York: Metropolitan Books, 2019. Pp. 370. Sources, notes, index.) In this sweeping book, historian Greg Grandin demonstrates the power, influence, and transformation of the frontier myth in the history of the United States. Writing for a popular audience, Grandin argues that President Trump's border wall signifies the true closing of the frontier, or the "promise of boundlessness" (7), more than one hundred years after Frederick Jackson Turner first declared the frontier closed. Instead of a reckoning with America's imagined limitlessness and its harmful impact on democracy, equity, the environment, and countless human bodies, Trump's acknowledgment of limits embraces domination, targeting those same victims of this once powerful myth. The End of the Myth covers three centuries of American history, beginning in colonial America with the Royal Proclamation Line of 1763. For colonists, the boundary separating Native and British territories hindered their ability to achieve individual independence through agriculture and land ownership. This was not the first time Euro-American settlers invaded Native lands; however, such acquisition solidified the notion that expansion would solve America's problems. In the post-independence era, Thomas Jefferson and James Madison advocated a westward-looking empire of liberty and extensions of the sphere, respectively, as ways to achieve "true" American democracy and freedom. As the United States industrialized in the nineteenth century, Americans saw the West as the [End Page 374] solution for all obstacles to progress, at least progress for ordinary white men, built on the backs of women, Native peoples, African Americans, and ethnic Mexicans. Slave owners removed Indians and instituted a growing cotton industry while paying little attention to a growing sectional crisis, and militias and military men achieved their masculinist dreams through violent expansion. Then came Turner and the so-called closing of the frontier, which introduced a new reading of limitlessness. In his 1893 speech, Turner solidified Anglo westward expansion as the essence of American democracy. The way to achieve progress and build America would now expand beyond its geopolitical borders. In 1898, three decades after the Civil War, northern and southern soldiers worked together to "save" the Caribbean and Philippines from Spanish tyranny. Yet white soldiers, reveling in the havoc they wreaked on people of color on the islands, employed violence against fellow African American military men. Frontiers also produced fear, which has continued to the present day. Early twentieth-century white nativists mapped their anxieties about a closed frontier onto U.S. borders and influenced the creation of the Border Patrol and immigration quotas. Americans viewed World War II, the New Deal, and the Cold War through a frontier lens, and the brutality of Vietnam built on the nineteenth-century Indian Wars and Spanish-American War as "another frontier war" (201). While Martin Luther King Jr. and other activists used the frontier myth to push alternative visions of America predicated on civil rights and antiwar critique, the Right advocated "the right to limitlessness," most markedly characterized by Ronald Reagan (214). Boundless U.S. interventions abroad and global trade in the late twentieth century helped restructure North American economies to benefit the few, leaving the many without living wages and, in many cases, a place to call home. The attacks of September 11, 2001, and the subsequent collapse of the economy once again transformed discussions of the frontier, and Americans responded with fear to what they perceived as chaos. By the election of President Obama, the frontier myth's safety valve had disappeared, giving rise to Trump and his wall, a symbol that "no longer pretends, in a world of limits, that everyone can be free—and enforces that reality through cruelty, domination, and racism" (275). The End of the Myth is an excellent intellectual history of the enduring frontier myth. It accessibly reframes the significance of U.S. expansion and adeptly ties the distant and recent pasts to the present day. Students of history as well as audiences interested...
