Brief history
Native-Americans inhabited the area where the City of Douglas and its surrounding areas are located before the arrival of the people of European ancestry from the East Coast of the United States. The principal Native-American tribe which inhabited southeastern Arizona were the Chiricahua Apaches. They called themselves the Chiricahua Apache (Apache: `great mountain’) after their former mountain home in southeast Arizona. Their own name true name is actually the Aiaha.

In the 1500s Spain claimed the area which they called New Spain, In 1535, Spanish explorer Cabeza de Vaca established a route from Mexico through the southwestern region of Arizona. Spanish Conquistadores then began to establish presidios throughout the region. Present-day Douglas is close to the San Bernardino Presidio of the late 1700s. In 1821, the Mexican War of Independence between Mexico and Spain came to an end and the territory of New Spain, which included present-day Arizona, was ceded to Mexico.

By the mid-1800s there were many cattle ranchers in the region, among them John Horton Slaughter. In 1854, the United States purchased the region from Mexico in what is known as the Gadsden Purchase. Americans of European descent from the East Coast of the United States began to arrive in the area. Some came to work as miners and others came to establish farms and ranches which provided food to the growing population.

The Phelps Dodge Corporation selected the area as a suitable site to establish a smelter for its copper mines in Bisbee. In 1888, mining pioneer Dr. James Douglas founded the Arizona and South Eastern Railroad. By 1901, the railroad line covered Bisbee, Fairbanks, Benson and finally Douglas. That same year the line was renamed the "El Paso and Southwestern Railroad".The town was founded in 1901 and was named after Dr. James Douglas. Two copper smelters operated at the site; the Calumet and Arizona Company Smelter and the Copper Queen.

Douglas was incorporated in 1905. It shares a border with the town of Agua Prieta, Mexico. In 1911, during the conflict known as the Border War, a United States Army camp, Camp Harry J Jones was established. During the Mexican Revolution the United States Army established Camp San Bernardino Ranch a.k.a. the Slaughter Ranch Outpost to deal with the border troubles.

There are many properties listed in the National Register of Historic Places and Historic landmarks in Douglas. Among them the Hotel Gadsden, the Southern Pacific Railroad Depot, the Grand Theatre and the first international airport in the United States. The Douglas area is also home to many cattle ranches, including the historical Slaughter Ranch. The Douglas-Williams House/Museum houses a comprehensive photographic collection, which chronicles much of the city's historic past.

The San Bernardino Ranch/ Slaughter Ranch
The San Bernardino Presidio was one of the presidios established during the 1700s where the San Bernardino Ranch is located. The San Bernardino Ranch was established between 1822 and 1855. On 2–3 December 1846, The Mormon Battalion passed through the San Bernardino Ranch. There they rested and recuperated near the ruins of the abandoned ranch house.

In 1886, John Horton Slaughter was elected sheriff of Cochise County. He would rather arrest a man than kill him. Nonetheless, he killed in the line of duty when necessary. While serving as sheriff, he helped the United States Cavalry track the Apache chief Geronimo. In 1893, he purchased a large area of land there. He paid $1 and twenty five cents for each foot. He purchased 60,000 feet of land and named it the Slaughter Ranch. The interesting thing about the ranch is that half of it was in the United States while the other half was in Mexico. It is located at 6153 Geronimo Trail. The ranch was listed in the National Register of Historic Places on October 15, 1966, reference: #66000170. It was also listed as a National Historic Landmark in 1964.
