National Labor Union (NLU) was begun at a conference in Baltimore in 1866. The organization was a pioneering coalition of trade unionists, feminists, and social reformers, oriented toward changing the American political and economic systems. In 1868, William Sylvis, leader of the Iron Molder's International Union, was elected as its first president. The NLU had some success in attracting members until 1869, when Sylvis died suddenly. After that, the NLU divided over politics and the issue of beginning a third party. In 1872, the organization, by then called the National Labor Reform Party, collapsed when its chosen presidential candidate backed out of the race.
