Small Jewish communities arose at the turn of the twentieth century in several southern Minnesota market towns. In each, Jews gathered for religious purposes. But it was only in Rochester that a formal synagogue, B’nai Israel, was established. The founding of Mayo Clinic in 1905 created a need for a local congregation that could serve Jewish patients. After almost a century of holding worship services in former residences, B’nai Israel built its first synagogue building in 2008.

The Ada Village Hall served as the center for local government in Ada for over a century. It was an important public meeting hall and social facility through the 1970s. Architecturally, the building is an excellent example of the combined city hall and fire hall buildings that were constructed in Minnesota during the early 1900s.

Two Jewish homes for the poor and elderly operated in the Twin Cities area through most of the twentieth century. They merged in 1971, then merged again in 1995 with another agency devoted to eldercare to form Sholom Community Alliance. Sholom operates two campuses, one in St. Louis Park and the other in St. Paul.

The St. Peter Armory was the first state-owned armory built in Minnesota. Architecturally, the structure is an excellent example of Minnesota's so-called "early period” armories, all of which predate World War I. The building is also important because it served as a center of military and social affairs in St. Peter.

Constructed in Minneapolis in 1919, the Northeast Neighborhood House (NENH) served both as a portal into American society for newly arrived immigrants from Eastern Europe and as an advocate for the neighborhood's underprivileged. It is a notable example of a social institution created solely for the betterment of the disadvantaged.

Edward Foote Waite was a distinguished Minneapolis judge and community leader. His involvement in public affairs spanned much of the twentieth century.

The Itasca forest during the late nineteenth century contained towering pines and numerous lakes. Individuals like surveyor Jacob Brower became captivated by the region and the wildlife that inhabited it. They recognized that the economic potential of northern Minnesota would change its landscape. Their effort to preserve Lake Itasca led them to contend with the lumber industry, public interests, and the politics that weaved between them.

The growth of cities and industry in the late nineteenth century brought sweeping changes to American society. Minneapolis and Saint Paul grew rapidly. Urban labor provided new opportunities for Minnesotans as well as new challenges. Business practices and labor rights became topics of heated debate. The Progressive movement spread amid growing concerns about the place of ordinary Americans in the new urban landscape.

Laura Ingalls Wilder was sixty-five when she published Little House in the Big Woods, a novel for young readers inspired by her childhood in the Big Woods of Wisconsin. Her book, and the others that followed, made her an icon of children's literature. The Little House series offered generations of children a glimpse into life on the nineteenth-century American prairie and immortalized a sod house on the banks of Minnesota's Plum Creek.

Ignatius Donnelly was the most widely known Minnesotan of the nineteenth century. As a writer, orator, and social thinker, he enjoyed fame in the U.S. and overseas. As a politician he was the nation's most articulate spokesman for Midwestern populism. Though the highest office he held was that of U.S. congressman, he shaped Minnesota politics for more than thirty years.
