Quick Summary

Louis Tikas was a prominent labor organizer, particularly known for his involvement with the United Mine Workers of America (UMWA). He was a key figure during the 1913-1914 Colorado coal strike, which involved thousands of miners protesting poor pay and working conditions.

The strike led to the tragic Ludlow Massacre on April 20, 1914. During this attack by the Colorado National Guard and company guards on a tent colony of striking miners and their families, Tikas was captured and killed. The massacre resulted in 25 deaths, including 11 children, and sparked further violence and federal intervention. Despite the workers gaining few immediate benefits, the strike ultimately led to an increase in UMWA membership.
