Wyatt Berry Stapp Earp was an American lawman and gambler in the American West, including Dodge City, Deadwood, and Tombstone. Earp was involved in the famous gunfight at the O.K. Corral, during which lawmen killed three outlaw Cochise County Cowboys. While Wyatt is often depicted as the key figure in the shootout, his brother Virgil was both Deputy U.S. Marshal and Tombstone City Marshal that day and had considerably more experience in law enforcement as a sheriff, constable, and marshal than did Wyatt. Virgil made the decision to enforce a city ordinance prohibiting carrying weapons in town and to disarm the Cowboys. Wyatt was only a temporary assistant marshal to his brother.

Deadwood is a city that serves as county seat of Lawrence County, South Dakota, United States. It was named by early settlers after the dead trees found in its gulch. The city had its heyday from 1876 to 1879, after gold deposits had been discovered there, leading to the Black Hills Gold Rush. At its height, the city had a population of 25,000, attracting Old West figures such as Wyatt Earp, Calamity Jane, and Wild Bill Hickok.
