The Farmers’ Alliances were not successful in influencing national farm policy in favor of farmers and needed to form a national political party as a result.

Explanation:

The Farmers’ Alliances were formed in 1875. in hopes to improve the economic conditions of agrarian workers.

The movement was made out of a few separate organizations -

whites on the South had the National Farmers' Alliance and Industrial Union in the Midwest, there was the National Farmers' Alliance for both white and black farmers African Americans on the South had their own Colored Farmers' National Alliance and Cooperative Union

As the economic movement, this Alliance didn't have much success. It wasn't united or influential and didn't have much of a political impact.

That is why, finally, Alliance decided to turn into the political movement with its own political candidate. In the early 1890s, Alliance formed the Populist (People's) Party which fought for the ideas of the Alliance, but with the political background and force.
