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. It stood just north of the Crow Wing River on its east bank, south and opposite the mouth of the Leaf River in what later became the Old Wadena County Park.

In the late 1800s, as diversified farms began to replace large bonanza farms in Minnesota and across the U.S., Polk County farmers realized they needed help. National groups with local branches, like the Farm Bureau, formed to help farmers organize and improve their representation in laws and education. Farmers in the western part of Polk County—a particularly fertile area due to the Red River Valley’s rich topsoil—came to rely on their farm organizations as they adapted to the rising cost of transporting produce to city markets.

Crookston’s Business and Professional Women’s club (BPWC), started in 1921, was more politically active in the 1960s and 1970s than in its early years. BPWC members made sure to cast their votes for causes important to women, including equal pay for equal work and the Equal Rights Amendment (ERA).

Gabriel Renville was a fur trader, a farmer, and the leader of the Sisseton-Wahpeton Dakota from 1867 until 1892. Related by blood to multiple Dakota bands and mixed-ancestry families, he opposed Ta Oyate Duta (His Red Nation, also known as Little Crow) and other Dakota who fought against settler-colonists in the U.S.–Dakota War of 1862. His choice angered some of his relatives, who saw him as serving the interests of colonists. After the war, he was one of many who worked to reacquire land for the Sisseton-Wahpeton people.

The Agricultural Extension Service of the United States (AES) began as an educational component of land-grant universities. In Minnesota as in other states, the federally funded and organized services of AES provide practical agricultural training to people outside of a university setting.

St. Paul’s Como Shops served as a major passenger-car repair facility on the Northern Pacific railroad between 1885 and the 1970s, providing employment to many St. Paul residents. The durability of the shops’ construction guaranteed their longevity, and in 1985 the facility was listed as a historic district on the National Register of Historic Places.

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.

Solomon Comstock earned his law degree from the University of Michigan in 1869 but worked with railroads when prospects of finding a job in his chosen career path seemed dim. In Moorhead, he began a law partnership and traded in real estate with the Northwest Land Company. In the 1880s, he worked with James J. Hill’s Northern Pacific Railway to plat townships across Minnesota.

As a legislator, Helen E. McMillan served Mower County for twelve years. She was also involved in the Red Cross, the Women’s League of Voters, the Human Rights Commission, and the United Council for Church Women.
