 Sheridan County, on the eastern base of the Bighorn Mountains, has long been an attractive location for human settlement since before the Crow Indians arrived in the region which they called a country in the right place. Sheridan County experienced rapid settlement after the conclusion of the Plains Indian Wars and Bighorn City became the first town. Railroad expansion and a favorable climate encouraged settlements for agriculture production, shipping, mining, and timbering across the county. The town of Sheridan became the hub of many of these activities and the county seat. Many of the settlers in the area were of British descent and Sheridan County gained a reputation for raising horses when F.D. Grizzle and Oliver Wallop, among others, moved to the county. Sheridan County supplied horses to the British Calvary during the Boar War and became a world-renowned polo destination after World War I. Queen Elizabeth II visited the county in 1984 to purchase polo ponies. Many early Wyoming dude ranches also began in Sheridan County. Agriculture and tourism continue to play an important role in the county, finding ways to thrive in a terrain that varies from mountains to lush valleys to dry plains.
