This year marks the 150th anniversary of _The Nation_ magazine, which was founded by abolitionists just months after the assassination of Abraham Lincoln. **Katrina vanden Heuvel**, London correspondent **D.D. Guttenplan**, and Nation writer **Chloe Maxmin** will discuss Guttenplan's long-awaited book, _The Nation: A Biography_, which chronicles the surprising story behind America’s oldest weekly magazine—the bickering abolitionists who founded it; the campaigns, causes and controversies that shaped it; the rebels, mavericks and visionaries who have written, edited and fought in its pages for 150 years and counting.
