Golconda was founded in 1869. The community was named for the ancient diamond mining center of Golkonda in India. The settlement had its start when discovery of copper, silver, gold, and lead brought entrepreneurs who opened mines and mills in the district. The town was a diverse society including both native-born European Americans as well as other groups including individuals of French, Portuguese, Paiute, and Chinese descent who all lived and worked in the small community. During 1898-1910, the town had a train depot, several hotels, a school, businesses, newspapers, and two brothels. Its population peaked at about six hundred in 1907-08. Although boosters predicted growth for Golconda, after 1910 the mines played out, leaving the region as an area of ranches and farms.
