World War I American military camps, such as Louisville’s Camp Zachary Taylor, were far more than training sites. As places where young people from different states, communities, and traditions met and negotiated life together, they served as vast laboratories for testing both Progressive Era Americanization policies and new ideas about religious pluralism in the United States. This lecture explores the impact of soldiers’ welfare services provided through independent religious organizations such as the Protestant YMCA, the Catholic Knights of Columbus, and the Jewish Welfare Board. It considers the goals that these different agencies brought into American military camps, and focuses on the responses of soldiers, particularly Jewish soldiers, as they trained both to fight and to redefine ideas about American religion.
