In time for the centennial of the United States’ entry into World War I, this collection of essays explores the war experience in Utah from the multiple perspectives of soldiers, nurses, and ambulance drivers who experienced the horror of the conflict firsthand to those on the home front whom the war transformed. Citizens at home took active roles in supporting the war effort. Some of Utah’s Native Americans and at least one Episcopal bishop resisted the war. The terrible 1918-1919 flu pandemic hit Utah and killed more victims around the world than those who died on the battlefields. A Red Scare and a fight over United States participation in a League of Nations followed the war. These essays help us understand the nature and complexity of the conflict and its impact on Utahns.
