<p>Originally published in 1986. Political machines and the bosses who ran them are largely a relic of the nineteenth century. A prominent feature in nineteenth-century urban politics political machines mobilized urban voters by providing services in exchange for voters&#39; support of a party or candidate. Allswang examines four machines and five urban bosses over the course of a century. He argues that efforts to extract a meaningful general theory from the American experience of political machines are difficult given the particularity of each city&#39;s history. A city&#39;s composition largely determined the character of its political machines. Furthermore while political machines are often regarded as nondemocratic and corrupt Allswang discusses the strengths of the urban machine approach--chief among those being its ability to organize voters around specific issues.</p>
