The Rock Springs massacre occurred on September 2, 1885, in the present-day United States city of Rock Springs, Wyoming, in Sweetwater County. The riot, between Chinese immigrant miners and white, mostly immigrant, miners, was the result of racial tensions and an ongoing labor dispute over the Union Pacific Coal Department's policy of paying Chinese miners lower wages than white miners. When the rioting ended, at least 28 Chinese miners were dead and 15 were wounded. Rioters burned 75 Chinese homes resulting in approximately US$150,000 in property damage. Tension between whites and Chinese immigrants in the late 19th century American West was particularly high, especially in the decade preceding the violence. The massacre in Rock Springs was the violent outburst of years of anti-" coolie" sentiment in the United States. In the immediate aftermath of the riot, federal troops were deployed in Rock Springs. They escorted the surviving Chinese miners, most of whom had fled to Evanston, Wyoming, back to Rock Springs a week after the riot. Reaction came swiftly from the era's publications. In Rock Springs, the local newspaper endorsed the outcome of the riot, while in other Wyoming newspapers, support for the riot was limited to sympathy for the causes of the white miners. The massacre in Rock Springs touched off a wave of anti-Chinese violence, especially in the Puget Sound area of Washington Territory.
