Daniel Walker Howe What Hath God Wrought: The Transformation of America, 1815-1343 Oxford University Press, 2007; 904 pages. Daniel Walker Howe's Pulitzer Prize-winning work spans a period that is book-ended by events that often gain more attention—the American Revolution and the Civil War. However, Howe shows in a comprehensive, yet engaging, style that the period from 1815 to 1848 was of crucial significance to the development of the country. Indeed, the material he covers includes well-known figures such as Andrew Jackson, John C. Calhoun, Henry Clay, and Daniel Webster; and famous events like Indian removal and the Trail of Tears, the battle over a national bank, the rise of Mormonism, the gold rush, and the women's rights convention in Seneca Falls, to name just a few. When summing up, Howe writes that his book “tells a story; it does not argue a thesis” (p. 849). However, his story is not without shape and emphasis. He has heroes, like John Quincy Adams, who was committed to “national unity, the restriction of slavery, and economic modernization” (p. 813), and villains, like Andrew Jackson, who supported the interests of slave owners and exacerbated division during his years in the White House. Howe's most powerful point, however, is not about any singular individual, but about the revolution in communication that took place during this 33-year period. He writes: “This revolution, with its attendant political and economic consequences, would be the driving force in the history of the era” (p. 5). It was the telegraph, newspapers, and railroads, he says, that made it possible to create a market economy, fostered religious revivalism and the organization of new social movements, and allowed for the rise of mass political par- ties that offered rival programs from which the electorate could choose. And while strife and struggle would ensue, Howe makes clear that these developments from the years between 1815 and 1848 established the foundation upon which modern America is based. Thovrin Tritter, University of London BOOKS IN BRIEF Lewis E. Lehrman Lincoln at Peoria: The Turning Point Stackpole Books, 2008; 412 pages. At the very beginning of Abraham Lincoln's reentry into political activism, he delivered a speech in Peoria, lllinois, on October 16, 1854, decrying the passage of Stephen A. Douglas's Kansas-Nebraska Act, which had opened the door to the expansion of slavery into the western territories. As Lewis Lehrman (who is a trustee of the New-York Historical Society and co-founder of the Gilder Lehrman Institute) painstakingly points out in Lincoln at Peoria (which is, amazingly, the first serious study of the Peoria speech), “it forms the foundation of his politics and principles, in the 1850s and in his presidency.” Indeed, it does, because the Peoria speech teems with the ideas that will become the stars Lincoln navigates by. Lincoln replied to Douglas with a vivid denunciation of the deceitfulness of the Kansas-Nebraska Act, and with an eloquent appeal to the incompatibility of slavery with the founding principles of the American republic: “It is wrong; wrong in its direct effect, letting slavery into Kansas and Nebraska and wrong in its prospective principle, allowing it to spread to every other part of the wide world.” Tolerating slavery has “soiled ... our republican robe,” Lincoln said. “Let us repurify it” so that “the succeeding millions of free happy people, the world over, shall rise up, and call us blessed, to the latest generations.” It is characteristic of Lehrman’s thoroughness that he not only sets the context and parses the arguments of the Peoria speech, but goes on to trace its connections into Lincoln’s presidential years, and then deals with the reputation of the Peoria speech in the hands of historians. As we see from Lehrman’s final chapter, too many of those historians, including J.G. Randall, Richard Hofstadter, and Robert Johannssen, have scanted either the substance or the intentions of the Peoria speech. It is high time that Lincoln’s speech at Peoria be seen for what it reallyis, the head of a great comet for which all that comes after is the tail. Allen C. Guelzo, Gettysburg College 115
