Filmmaker Gary Kaunonen of KCC-TV in International Falls just released a new documentary about a pivotal time in Northern Minnesota’s labor history. It’s called “Northern Minnesota’s Labor Wars.” The years 1916 and 1917 brought major labor uprisings in the mines of the Mesabi Iron Range and the lumber camps of the state’s far northern pine forests. These events not only shaped local history, but became vital turning points in the national and international labor movement.
