The Sand Creek Massacre was the deadliest day in Colorado’s history, and it changed Cheyenne and Arapaho people forever. At sunrise on November 29, 1864, the US Army attacked a camp of mostly women, children, and elders on Big Sandy Creek in southeastern Colorado. The soldiers murdered more than 230 peaceful people.
History Colorado is telling the history of that betrayal from the perspectives of Cheyenne and Arapaho Tribal representatives, drawn from oral histories that have been passed down for generations. Cheyenne and Arapaho people continue living with the unresolved trauma the massacre left behind. For many Cheyenne and Arapaho people, the Sand Creek Massacre isn’t just history, it’s family history.
