History & Stories
A Cowboy Contest That Became a Colorado Legend
Before Deer Trail was incorporated, this part of the Eastern Plains was cattle country. The town's best-known story reaches back to July 4, 1869, when ranch hands gathered for a Bronco Bustin' Contest β an event Deer Trail celebrates as the world's first rodeo. The town itself grew with the arrival of the Kansas Pacific Railway in 1870, becoming a shipping point for grain, livestock and eggs before being platted in 1875 and incorporated in 1920.

Colorado Recognizes the Claim
For the rodeo centennial, the Colorado General Assembly adopted a joint resolution recognizing Deer Trail's July 4, 1869 event as the first rodeo held in the world. Other Western communities also make early-rodeo claims, making the story part of a larger debate about rodeo history.
