Founded in 1934, the american liberty league fought the new deal during six years, counting with a most conservative supreme court. They were concern with 'limiting individual rights', the league was mostly formed by proeminent politicians and elite business man who had no interest in the reforms in labor such as minimum wage adopted to establish the economy .
The League called businessmen to defy the National Labor Relations Act, in a lobby attempt that the Supreme Court would declare it unconstitutional, and led campaigns against social new deal policies .
