In the decades before World War I, industrialists such as John D. Rockefeller had become millionaires; by the early years of the 20th century labor unrest blossomed in the United States, particularly in the coal mine industry. Strikes grew into riots occurring throughout the US, and then into full scale battles, the most famous of which was in 1914, the Ludlow Coal Massacre, when Colorado National Guard opened fire on a tent city of striking miners and their families in Ludlow Colorado.Basic Facts

Rockefeller, owner of the Colorado Fuel and Iron Company.
