The Populist Party
The Populist Party, otherwise known as the People’s Party was a grass-roots political party that focused on the small farmer. This brought different ethnicities and religions together, but it was not a party of “have-nots.” Farmers who owned physical property were more likely to join the movement. It also coincides with the Farmers Alliance movement.
This article gives a brief explanation of the Populist Party in South Dakota, mainly Marshall County.
