The Mann–Elkins Act was a 1910 United States federal law that was among the Progressive era reforms.  The Act got its name from congressmen Stephen Benton Elkins and James Robert Mann.  Both congressmen sponsored and created legislation about interstate trade which would go on to be signed into law.  The Mann–Elkins Act would further expand upon the work by these two men (the Elkins Act and the Mann Act).  The act was part of an initiative by President William Howard Taft "to regulate destructive competition and unfair trade practices" in order to make good on promises made during his campaign.  It was created because, "Taft believed that the 1887 Interstate Commerce Act should be amended so as to permit railroads to make traffic agreements, which would preserve the principle of competition, and avoid the common control of competing railroad lines."  This act was in direct response to railroad price increase that took place in 1910.  The Act placed a price ceiling on interstate commerce and transportation companies to ensure fair market value of prices.  The Act extended the authority of the Interstate Commerce Commission (ICC) to regulate the telecommunications industry, and designated telephone, telegraph and wireless companies as common carriers. .  The act placed all telecommunications under the ICC's control.  It was passed by the United States Senate, 50-12.
