Locofoco Party

In U.S. history,the locofocos were a radical wing of the Democratic Party, organized in New York City in 1835. Made up primarily of workingmen and reformers, the Locofocos were opposed to state banks, monopolies, paper money, tariffs, and generally any financial policies that seemed to themantidemocratic and conducive to special privilege. The Locofocos received their name (which was later derisively applied by political opponents to all Democrats) when party regulars in New York turned off the gas lights to oust the radicals from a Tammany Hall nominating meeting.The radicals responded by lighting candles with the new self-igniting friction matches known as locofocos, and proceeded to nominate their own slate.
