Wilson was a leading force in the Progressive Movement, and during his first term, he oversaw the passage of progressive legislative policies unparalleled until the New Deal in the 1930s. Taking office one month after the ratification of the 16th Amendment of the Constitution permitted a federal income tax, he helped pass the Revenue Act of 1913, which reintroduced a federal income tax to lower tariff rates. Other major progressive legislations passed during Wilson's first term include the Federal Reserve Act, the Federal Trade Commission Act of 1914, the Clayton Antitrust Act, and the Federal Farm Loan Act. 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.
