The 1916–1917 northern Minnesota lumber strike was a labor strike involving several thousand sawmill workers and lumberjacks in the northern part of the U.S. state of Minnesota, primarily along the Mesabi Range. The lumber workers were organized by the Industrial Workers of the World (IWW) and primarily worked for the Virginia and Rainy Lake Lumber Company, whose sawmill plant was located in Virginia, Minnesota. Additional lumberjacks and mill workers from the International Lumber Company were also involved. The strike first began with the Virginia and Rainy Lake mill workers on December 28, 1916, and among the lumberjacks on January 1, 1917. The strike lasted for a little over a month before it was officially called off by the union on February 1, 1917. Though the strike had faltered by late January and had resulted in many arrests and the suppression of the IWW's local union in the region, the union claimed a partial victory, as the lumber companies instituted some improvements for the lumberjacks' working conditions. The roots of this strike stemmed from a previous strike involving miners on the Mesabi Range that ended in a partial victory for the workers. During this strike, the IWW became involved and established a local union in the region called the Metal Mine Workers' Industrial Union No. 490, which was based in Virginia. Following the end of the miners' strike, Local 490 began to organize lumber workers in the region. At the time, the Virginia and Rainy Lake Lumber Company operated the world's largest white pine sawmill plant in Virginia, which employed about 1,200 workers, and they had roughly 2,000 lumberjacks on their payroll at any given time. Through late 1916, Local 490 continued to organize these workers, working alongside the Agricultural Workers Organization No. 400, a subgroup of the IWW that had been trying to organize lumberjacks in the region for the past year. By December 1916, more militant individuals within the union were calling for a strike against the company, though IWW higherups such as General Secretary-Treasurer Bill Haywood were weary of this, thinking that there had not been enough time to adequately plan and organize a successful strike. Nonetheless, on December 24, 1916, about 700 workers met to create a list of demands for both the mill workers and the lumberjacks that included reduced working hours, higher pay, better working conditions, and changes to scheduling.
