Administrative Record Group

During the Fall of 1913 through the Fall of 1914 CF&I coal miners went on strike for better wages and working conditions. The workers clashed with CF&I management throughout this period. There were a number of very violent episodes, most notably the Ludlow Massacre on April 20, 1914. These pages from the CF&I Board of Directors Minutes document the official CF&I Board proceedings during that time period.

Financial Record Group

Financial records may sound boring, but they can yield a wealth of information for researchers.


This Daybook from 1910-1911 is one example.

Industrial Relations Record Group

The Industrial Relations Record Group contains extensive documentation about labor relations issues from significant periods of labor unrest for CF&I employees and management. One example of research on this collection is Representation and Rebellion: The Rockefeller Plan at the Colorado Fuel and Iron Company, 1914-1942, by CSU-Pueblo History Professor Dr. Jonathan Rees. Below are a few files from the Industrial Relations Sub-series, Pre-Unionization Documentation, 1900-1938. A complete listing of this sub-series is available on the Rocky Mountain Online Archive. The files we selected contain “X-reports,” a series of reports filed by CF&I infiltrators into the union ranks of the CF&I coal mining towns during a 1927-1928 IWW strike.
