Events and Accomplishments of William Howard Taft’s Presidency In 1909, the Payne-Aldrich Tariff Act passed. This changed the tariff rates from 46 to 41%. It upset both the Democrats and the progressive Republicans who felt that it was just a token change. One of Taft's key policies was known as Dollar Diplomacy. This was the idea that America would use the military and diplomacy to help promote U.S. business interests overseas. For example, in 1912 Taft sent marines to Nicaragua to help stop a rebellion against the government because it was friendly to American business interests. Following Roosevelt into office, Taft continued to enforce antitrust laws. He was key in bringing down the Standard Oil Company in 1911. Also during Taft's term in office, the sixteenth amendment was passed that allowed the U.S. to collect income taxes. Post-Presidential Period Taft was defeated for reelection when Roosevelt stepped in and formed a rival party called the Bull Moose Party allowing Democrat Woodrow Wilson to win. He became a law professor at Yale (1913-21). In 1921, Taft got his long-desired wish to become Chief Justice of the U.S. Supreme Court where he served until one month before his death. He died on March 8, 1930, at home. Historical Significance Taft was important for continuing Roosevelt's antitrust actions. Further, his Dollar Diplomacy increased the actions that America would take to help protect its business interests. During his time in office, the last two contiguous states were added to the union bringing the total up to 48 states.
