<em>One of the most infamous of these political machines was Tammany Hall, the Democratic Party machine that played a major role in controlling New York City and New York politics and helping immigrants, most notably the Irish, rise up in American politics from the 1790s to the 1960s.</em>
<em>A political machine is a political group in which an authoritative boss or small group commands the support of a corps of supporters and businesses (usually campaign workers)</em>
