In the spring of 2010, I walked into The New York Times and proposed that the paper blog the Civil War. Out of that grew the Disunion series, which from October 30, 2010 until last week did just that–wote about the war, in matters great and small, generally corresponding to the events of that day 150 years before. Before the series ended nearly 1000 posts later, literally dozens of contributors, famous historians and civilian researchers alike, combined to cover the war.”`Disunion’ has been like no other intellectual or journalistic enterprise I’m aware of: a sustained five-year conversation among dozens of historians (academic and not) representing every specialty and viewpoint,” wrote historian and series contributor Adam Goodheart. “It was a conversation that included an even broader and more diverse public around the world. It brought leading scholars and laypeople together in ways that I think have never been equaled. It truly serves as a model for those in many other fields who aspire to be “public intellectuals” , not to mention enduring as a resource for educators, students, and scholars. Just a remarkable achievement.” Much credit and thanks belongs to the Times, especially editors Clay Risen and Geeorge Kalogerakis. To conclude the series, the Times assembled –in their words–“an all-star cast of Disunion contributors and friends: David Blight, Ken Burns, Adam Goodheart and Jamie Malanowski”–to respond to readers’ questions. Here is that discussion, in which I was very proud to have participated.
