Passage: Treaties between European settlers and the Dakota and Ojibwe gradually forced the natives off their lands and on to smaller reservations. In 1861, residents of Mankato formed the Knights of the Forest, with a goal of eliminating all Indians from Minnesota. As conditions deteriorated for the Dakota, tensions rose, leading to the Dakota War of 1862. The result of the six-week war was the execution of 38 Dakota and the exile of most of the rest of the Dakota to the Crow Creek Reservation in Dakota Territory. As many as 800 white settlers died during the war.Logging and farming were mainstays of Minnesota's early economy. The sawmills at Saint Anthony Falls, and logging centers like Pine City, Marine on St. Croix, Stillwater, and Winona, processed high volumes of lumber. These cities were situated on rivers that were ideal for transportation. Later, Saint Anthony Falls was tapped to provide power for flour mills. Innovations by Minneapolis millers led to the production of Minnesota "patent" flour, which commanded almost double the price of "bakers'" or "clear" flour, which it replaced. By 1900, Minnesota mills, led by Pillsbury, Northwestern and the Washburn-Crosby Company (a forerunner of General Mills), were grinding 14.1 percent of the nation's grain.
