History told in the first person. Oates has chosen thirteen people to relate their understanding of the events that we know now led to the Civil War. It is an engaging read (he has written biographies on at least two of the individuals previously - Lincoln and Brown), with deep roots in each of these individual's personal and public writings (Jefferson, Clay, Calhoun, Turner, Stowe, Brown, Garrison, Douglass, Fitzhugh, Douglas, Lincoln, Davis, Chestnut). He does a good job of examining events and time from several vantage points and getting both northern and southern opinion. While it claims to cover the period 1820-1861, two thirds of the book covers the period 1857-1861 and the Lincoln-Douglas debates get wide coverage. This is not a drawback in my opinion, but the reader should be warned. Slavery is central to the argument and leads to division as America grows in both territory and population. Without Douglas and Clay the story would veer too much to extreme positions on either side (and not the general racism and ambivalence of the "average" American of the 1850s). My other warning is that I wanted even more intellectual history, but instead much time was spent carrying the narrative history forward as characters related and responded to the events of the day.
