Populist Vanguard : A History of the Southern Farmers' Alliance

Significant as a political, economic, and social organization, the southern Farmers' Alliance was the largest and most influential farmers' organization in the history of the United States until the rise of the American Farm Bureau Federation. McMath suggests that the ideas advanced by the People's party in the 1890s had been incubated within the alliance and that the shared experience of 1.5 million rural Americans helped give those ideas power in the Populist crusade.
