Farmers first sought to solve their own problems through the economic cooperatives founded by the Grange. When these self-help programs proved a failure, farmers began to demand that government respond to their plight.
The political and economic planks of the Populist platform came directly from the Ocala Demands of the Farmers Alliance - the sub treasury program, the free coinage of silver, an end to protective tariffs on manufactured goods, the abolition of national banks, a progressive federal income tax, the direct election of U.
