During the extended Cold War standoff between the United States and the Soviet Union, many Minnesotans prepared for the terrifying possibility of nuclear war by participating in a variety of civil defense efforts. The civil defense strategies employed in Minnesota changed significantly as the perceived military threat evolved.

After the United States entered World War I in 1917, Minnesota women, like Americans across the nation, were called to contribute to the war effort. Though some went to Europe and served as nurses, drivers, and aid workers on the battlefields, many more participated on the home front. They took on new jobs, conserved vital resources, and joined volunteer organizations. At the same time, they struggled to come to terms with conflicting ideals of patriotism, loyalty, and what it meant to be an American.
