The Wyoming Stock Growers Association (WSGA) is an American cattle organization that started in 1872 among Wyoming cattle ranchers to standardize and organize the cattle industry but quickly grew into a political force that has been called "the de facto territorial government"[1] of Wyoming's organization into early statehood, and wielded great influence throughout the Western United States.[2]
The WSGA is still active to this day. It is best known for its rich history and is perhaps most famous for its role in Wyoming's Johnson County War.
