Wisconsin State Federation of Labor
The Wisconsin State Federation of Labor, affiliated with the American Federation of Labor, was the largest federation of labor unions in Wisconsin, from its formation in 1893 at the behest of the Milwaukee Federated Trades Council to its 1958 merger with the smaller CIO-affiliated Wisconsin State Industrial Council to form the Wisconsin AFL-CIO.
A number of WSFL leaders were also elected to public office in Wisconsin, in part due to its roots in and alliance with the Socialist Party, especially Milwaukee's so-called Sewer Socialists.Notable WSFL activists
