“In this much-needed and courageous book, Anne Wagner lays down a gauntlet to all those interested in modern and contemporary art: to think anew about these works by canonic artists, and about the relationship of art to recent history and politics. Wagner presents an exhilarating and innovative set of closely worked historical arguments that are remarkably timely, and her lucid prose makes complex ideas and critical debates accessible to a broad audience.”—Briony Fer, Professor of History of Art, UCL “In A House Divided, Anne Wagner takes on the so-called post-war era in American art and asks searching questions about what that term might mean now, amid cultural division and perpetual war. Far more than a sum of its parts, this collection of essays is essential reading on American artists' ‘post-war’ responses to nationalism, state violence, and the 1960s.”—Mignon Nixon, author of Fantastic Reality: Louise Bourgeois and a Story of Modern Art
