Since its founding in 1859, the Minnesota State Fair had been an essential yearly tradition in the agricultural state. However, after the United States entered World War I in 1917, the fair took on an entirely new significance. Organizers reframed the event as a “Food Training Camp” that showed Minnesotans how to produce and conserve resources vital to the Allied war effort.

During the early twentieth century, the population of the Iron Range was among the most ethnically diverse in Minnesota. Tens of thousands of immigrants arrived from Finland, Austria-Hungary, Italy, Sweden, Norway, Canada, England, and over thirty other places of origin. These immigrants mined the ore that made the Iron Range famous and built its communities.

The March 1963 murder of St. Paul wife and mother Carol Thompson shocked the Twin Cities as few local crimes have. Despite community fears of a homicidal maniac, investigators soon focused on T. Eugene "Cotton" Thompson, the victim’s husband, as their prime suspect. Three and a half months after the murder, Thompson was arrested and charged in connection with his wife’s death. In December 1963 he was convicted of first-degree murder and sentenced to life in prison.

Clontarf, a railroad town in Swift County, was established by Bishop John Ireland of St. Paul in 1877 as a Catholic colony on the prairie. Early arrivals named Clontarf for the site of the eleventh-century victory of the Irish king Brian Boru over Viking invaders.

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.
