The Business and Professional Women’s Foundation (BPW/USA) was started in 1919 to improve job conditions and raise pay rates for working women. At the first meeting of the foundation’s Crookston chapter in 1921, over 100 women gathered. In its early years, the club donated volunteer time and money to local causes, including the Camp Fire Girls, Crookston’s Drum and Bugle Corps, and milk and medical aid for needy school children.

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 Cadotte Post was a fur trade encampment in the late eighteenth century—one of three archaeological sites in Wadena County identified through Ojibwe oral tradition as a late-1700s trading fort.

In September of 2010, the Minnesota Twins unveiled a memorial to highlight Calvin Griffith, their first owner. While Griffith is credited with bringing professional baseball to Minneapolis, his racist attitudes and actions outshine his accomplishments.

In the mid-twentieth century, Anoka County's Carlos Avery Game Farm helped to build populations of dwindling game bird species, such as the bob white quail, chukar partridge, and ring-necked pheasant. A National Register-listed historic district since 1991, it is now part of the nearly 25,000-acre Carlos Avery Wildlife Management Area (WMA) and has become a reserve for deer, waterfowl, and other woodland animals and birds.

Carver County, founded in 1855, is home to the Minnesota and Crow Rivers, along with 125 lakes. Located southwest of the Twin Cities, it is part of the seven-county metro area.

County resident O.D. Sell founded the Carver County Historical Society (CCHS) in 1940. The original task was to collect and preserve the history of Carver County and Minnesota. He had a large personal collection of objects relating to the county's history that he wanted to share with the public. This forms the core of the CCHS collection.

The city of Carver has a long and rich history as one of the earliest communities in Carver County. Located on the Minnesota River, it was often the first place immigrants to Carver County visited. From there, they spread out to other towns and farms.
