In his new book, David Kertzer, the Pulitzer Prize-winning author of “The Pope and Mussolini,” takes on a pivotal, untold story: the bloody revolution that stripped Pope Pius IX of political power and signaled the birth of modern Europe. With a combination of gripping, cinematic storytelling and keen historical analysis, rooted in an unprecedented richness of archival sources, Kertzer sheds fascinating new light on the end of rule by divine right in the West. Kertzer joins scholars from Brown, Harvard and Fordham Universities in a panel discussion on the topic. Joukowsky Forum, Watson Institute, 111 Thayer Street.
