Our Shared History
Before the town of Niwot was founded, the Boulder Valley was the sovereign, legally recognized homeland of the Arapaho and Cheyenne people. To build genuine relationships today, we must first confront the unvarnished history of the land beneath our feet—tracing the devastating path from the 1858 Gold Rush to the Sand Creek Massacre and the forced exile of Indigenous communities.
Draft in progress — This timeline is still being developed and will be updated soon.
1859–1861
The discovery of gold triggered a massive influx of white settlers. These prospectors illegally established towns, ranches, and political structures on sovereign Arapaho and Cheyenne lands. They ignored federal treaties and quickly erased Native sovereignty from the map.
1862–1864
Invasive white migration destroyed native grazing lands and scattered the life-sustaining buffalo herds. Local politicians amplified isolated conflicts into public hysteria to justify military mobilization and war. Cheyenne and Arapaho peace chiefs attended the Camp Weld Council seeking peace, but were deceptively directed to military posts instead.
1864
Colorado volunteer troops launched a devastating, unprovoked surprise attack on a peaceful Cheyenne and Arapaho encampment. The soldiers ignored flags of truce and murdered more than 230 people, mostly women, children, and the elderly. This deliberate act of violence mortally wounded Chief Nowoo3 and destroyed the region's primary voice for peace.
1865–1868
The federal government admitted wrongdoing at Sand Creek but continued a policy of violent removal and treaty coercion. Surviving tribes were forced to surrender their Colorado claims and relocate to reservations in Indian Territory. Unrelenting military campaigns, like the Washita Massacre, successfully extinguished tribal claims to Colorado.
1869–1875
The federal government implicitly supported the mass extermination of buffalo to starve the remaining Plains Indians into submission. With Native populations exiled, Boulder County experienced a massive boom in agricultural settlement and railroad development. Settlers finalized their occupation of the valley by founding the town of Niwot, named in bitter irony after the fallen Arapaho Chief.
