Manifest Destinies: America's Westward Expansion and the Road to the Civil War

The 1840s was a decade of exuberant national growth and consolidation that laid the groundwork for schism and strife, argues this colorful history. Woodworth (Nothing but Victory) presents a vivid, episodic pageant of westward-ho empire building: settlers trekking along the Oregon Trail, Forty-Niners bound for the California gold rush, Mormons battling their way toward the promised land of Utah. Woodworth contrasts this flood of pioneering and settlement with a rickety, sclerotic political party system that papered over the problem of slavery, epitomized by the vapid populist sloganeering—"Tippecanoe, and Tyler too!"—of Whig presidential candidate William Henry Harrison in 1840. The themes collide in the book's centerpiece narrative of the Mexican War, which Woodworth, an accomplished Civil War historian, recounts with panache. The author's thesis—that the issue of slavery in the conquered Mexican territories wrecked a fragile national consensus—isn't original, but he elaborates it well, with entertaining, acid-etched sketches of egotistical politicians (and some random potshots at big government and "cultural elites" that seem cribbed from a Tea Party rally). This is narrative history writ large and vigorously—with foreshadowings of tragedy. 16 pages of photos; 19 maps. (Nov.)
