The Greenback Party of 1876 drew the support almost exclusively from farmers — few urban workmen cast ballots for the Greenback ticket. The situation changed somewhat in the summer of 1877, however, when a strike movement erupted across the country, leading to the suppression of local strike actions by Federal troops and a radicalization of workers. A myriad of local political organizations, independent not only of the Republican and Democratic Parties but also of the fledgling Greenback Party sprung up around the country, concentrated in the states of Ohio, Pennsylvania, and New York.
