Tombstone is a city in Cochise County, Arizona, United States, founded in 1879 by prospector Ed Schieffelin in what was then Pima County, Arizona Territory. It became one of the last boomtowns in the American frontier. The town grew significantly into the mid-1880s as the local mines produced $40 to $85 million in silver bullion, the largest productive silver district in Arizona. Its population grew from 100 to around 14,000 in less than seven years. It is best known as the site of the Gunfight at the O.K. Corral and presently draws most of its revenue from tourism.

John Peters Ringo was an American Old West outlaw loosely associated with the Cochise County Cowboys in frontier boomtown Tombstone, Arizona Territory. He took part in the Mason County War in Texas during which he committed his first murder. He was arrested and charged with murder. He was affiliated with Cochise County Sheriff Johnny Behan, Ike Clanton, and Frank Stilwell during 1881–1882. He got into a confrontation in Tombstone with Doc Holliday and was suspected by Wyatt Earp of having taken part in the attempted murder of Virgil Earp and the ambush and death of Morgan Earp. Ringo was found dead with a bullet wound to his temple which was ruled a suicide. Modern writers have advanced various theories attributing his death to Wyatt Earp, Doc Holliday, Frank Leslie or Michael O'Rourke.

Fairbank is a ghost town in Cochise County, Arizona, next to the San Pedro River. First settled in 1881, Fairbank was the closest rail stop to nearby Tombstone, which made it an important location in the development of southeastern Arizona.

Today Fairbank is located within the San Pedro Riparian National Conservation Area.

One witness identified his son Ike Clanton as a participant in the murder of Morgan Earp. Billy Clanton and Ike were at the O.K. Corral. "Old Man" Clanton was reportedly involved with stealing cattle from Mexican ranchers and re-selling them in the United States.

The Earp Vendetta Ride was a deadly search by a federal posse led by Deputy U.S. Marshal Wyatt Earp for a loose confederation of outlaw "Cowboys" they believed had ambushed his brothers Virgil and Morgan Earp, maiming the former and killing the latter. The two Earp brothers had been attacked in retaliation for the deaths of three Cowboys in the Gunfight at the O.K. Corral on October 26, 1881. From March 20 to April 15, 1882, the federal posse searched southeast Cochise County, Arizona Territory for the men they believed were responsible for the attacks on Virgil and Morgan. Several suspects had been identified and were charged, but were soon released by the court, owing in some cases to legal technicalities and in others to the strength of alibis provided by the Cowboy gang. Wyatt subsequently pursued the suspects with a federal warrant.

The Cochise County Cowboys is the modern name for a loosely associated group of outlaws living in Pima and Cochise County, Arizona in the late 19th century. The term "cowboy", as opposed to "cowhand," had only begun to come into wider usage during the 1870s. In that place and time, "cowboy" was synonymous with "cattle rustler". Such thieves frequently rode across the border into Mexico and stole cattle from Mexican ranches that they then drove back across the border to sell in the United States. Some modern writers consider them to be an early form of organized crime in America.

Cochise County in southeastern Arizona was the scene of a number of violent conflicts in the 19th-century and early 20th-century American Old West, including between white settlers and Apache Indians, between opposing political and economic factions, and between outlaw gangs and local law enforcement. Cochise County was carved off in 1881 from the easternmost portion of Pima County during a formative period in the American Southwest. The era was characterized by rapidly growing boomtowns, the emergence of large-scale farming and ranching interests, lucrative mining operations, and the development of new technologies in railroading and telecommunications. Complicating the situation was staunch resistance to white settlement from local Native American groups, most notably during the Apache Wars, as well as Cochise County's location on the border with Mexico, which not only threatened international conflict but also presented opportunities for criminal smugglers and cattle rustlers.

Although it was thwarted by Jeff Milton, who managed to kill "Three Fingered Jack" Dunlop in an exchange of gunfire, the train robbery was unique for being one of the few to have occurred in a public place and was also one of the last during the Old West period.

A few unmarked graves have been identified, but because of theft, vandalism, and erosion, the site has been heavily damaged.
