Dr. Chris McDonald, professor of political science, will be speaking to the Cass County Historical Society on June 9 about the shadow cast by the World War I over the rest of the 20th century and continues into the 21st century. In his discussion, McDonald will examine some of the issues that lie behind the outbreak of the “Great War,” trace the development of the conflict focusing on some of the ways that it differed from previous conflicts and presaged many modern wars, and look at the contested nature of the peace that followed it.
