Dissent during periods of crisis can be a difficult subject to discuss, even among reasonable people, and this thoughtful digital exhibit from the University of California at Irvine illuminates this subject quite nicely. The items in the exhibit are from their Department of Special Collections and Archives, and the focus of this particular collection is to examine “issues of war, peace, dissent and dialogue during critical periods in the 20th century.” There are six sections of the exhibit which include “Protest during the Vietnam War”, “The Internment of Japanese Americans during WWII”, and “McCarthyism during the Cold War”. Visitors can click on each of these sections to view digitized images of ephemera (such as artworks, pamphlets, and posters) that are representative of these times of dissent and debate. Visitors should not miss the “Conscientious Objectors in World War II” area, as it contains images from a pacifist handbook published in 1939 and items published by groups like the Quakers and the Mennonites.
