The presidency of Woodrow Wilson began on March 4, 1913 at noon when Woodrow Wilson was inaugurated as president of the United States, and ended on March 4, 1921. While the passing of the Adamson Act — which imposed an 8-hour workday for railroads - he averted a railroad strike and an ensuing economic crisis. Concerning race issues, Wilson's administration enforced segregationist policies for government agencies. Upon the outbreak of World War I in 1914, Wilson maintained a policy of neutrality, while pursuing a moralistic policy in dealing with Mexico's civil war. Wilson established the first modern propaganda office, the Committee on Public Information (CPI), headed by George Creel. Creel set out to systematically reach every person in the United States multiple times with patriotic information about how the individual could contribute to the war effort. A 2017 C-Span poll of historians ranked Wilson as the 11th best president. However, a 2006 poll of historians ranked Wilson's unwillingness to compromise on the Treaty of Versailles as the fourth-worst mistake made by a sitting president.
