May 11, 1958, marked the centennial for Minnesota's admission to statehood. The Polk County Centennial was observed concurrently with the Minnesota Statehood Centennial.
The Polk County Board of County Commissioners funded various centennial observances. One project funded was an update the county history. T. M. McCall was given the responsibility of selecting a committee to work out the historical assignment. This work the CENTENNIAL HISTORY OF POLK COUNTY is the result. The history is intended to be a supplement to the 1916 History and Biography of Polk County. Polk County Board of County Commissioners granted permission to digitize this document and make it available.
