ABSTRACT
The nineteenth century ended with the economic regulation of anti-trust as the country's main tool for containing the large corporation. The resulting public outcry helped fuel the Progressive Movement, by far the dominant reform movement of the early twentieth century. However, most critics now believed that these new economic organizations were also responsible for unparalleled economic growth and had the potential for great economic efficiency that could be used to achieve social goals. In response to the Progressive Era's numerous efforts to pass social regulations, the business community adopted a two-pronged strategy of opposition, the first involving the courts and the second the legislative process. As the strongest period of reform to date, the Progressive Era produced lasting changes to the nation's politics. The appearance of a radical wing in the labor movement helped to trigger a wave of industrial violence, especially the dynamiting of the Los Angeles Times building in 1910 by two union leaders.
