rodeo, Sport involving a series of contests derived from North American cowboy skills. Rodeos typically feature competitive or exhibition bronco riding, calf roping, steer wrestling, and Brahma bull riding. The sport developed from informal competitions among cowboys held from the mid-19th century. Denver is traditionally accepted as the birthplace of paid spectator rodeo, in 1887. The oldest surviving annual show is the Frontier Days celebration in Cheyenne, Wyo. (established 1897). The Calgary Stampede has been held annually in Alberta, Can., since 1923. In calf roping and steer wrestling, the contestant seeks to bring down the animal in the shortest possible time. In riding events, contestants seek to stay on their mounts as long as possible and are awarded points for style, control, and other factors.
