Theodore Roosevelt was the 26th President of the United States from 1901 to 1909. He was a progressive reformer who established a number of important policies around conservation and antitrust laws. His successor, William Howard Taft, pursued antitrust policy aggressively but was more conservative than Roosevelt. Woodrow Wilson defeated Taft in the 1912 election and pushed progressive policies as president from 1913 to 1921, including establishing the Federal Reserve system and passing antitrust and labor laws.
