South Dakota is a landlocked state in the North Central region of the United States. It is also part of the Great Plains. South Dakota is named after the Dakota Sioux tribe, which comprises a large portion of the population — with nine reservations currently in the state — and has historically dominated the territory. South Dakota is the 17th-largest by area, but the fifth-least populous, and the fifth-least densely populated of the 50 United States. Pierre is the state capital, and Sioux Falls, with a population of about 213,900, is South Dakota's most populous city. The state is bisected by the Missouri River, dividing South Dakota into two geographically and socially distinct halves, known to residents as "East River" and "West River". South Dakota is bordered by North Dakota to the north, Minnesota to the east, Iowa to the southeast, Nebraska to the south, Wyoming to the west, and Montana to the northwest.
Sioux Falls is the most populous city in the U.S. state of South Dakota and the 121st-most populous city in the United States. It is the county seat of Minnehaha County and also extends into northern Lincoln County to the south, which continues up to the Iowa state line. The population was 192,517 at the 2020 census, and in 2022, its estimated population was 202,078. According to city officials, the estimated population had grown to 213,891 as of early 2024. The Sioux Falls metro area accounts for more than 30% of the state's population. Chartered in 1856 on the banks of the Big Sioux River, the city is situated in the rolling hills at the junction of interstates 29 and 90.

The 1930 South Dakota gubernatorial election was held on November 4, 1930. Incumbent Democratic Governor William J. Bulow declined to run for re-election to a third term, instead opting to successfully run for the U.S. Senate. The Republican nomination was hard-fought and the primary was crowded; because no candidate received 35% of the vote, state law required that the nomination be decided at a state party convention. There, former State Senator Warren Green, the last-place finisher in the primary, defeated Secretary of State Gladys Pyle, the plurality winner. In the general election, Green faced D. A. McCullough, the state's Rural Credits Commissioner and the Democratic nominee. Despite Bulow's success in the preceding two elections, Green defeated McCullough by a decisive margin—even as Bulow himself was elected to the U.S. Senate.
