High prices for supplies contributed to the creation of the Farmers' Alliance.
The Farmers Alliance was an organized agrarian economic movement among American farmers that developed and flourished in 1875.
A number of parallel but independent political organizations were involved in the movement such as, the National Farmers' Alliance and Industrial Union among the white farmers of the South, the National Farmers' Alliance among the white and black farmers of the Midwest and High Plains, where the Granger movement had been strong, and the Colored Farmers' National Alliance and Cooperative Union.
