The year 1920 was significant or a number of reasons, several of which had a direct impact on Major League Baseball and its future. The United States refused to join The League of Nations, the brainchild of President Woodrow Wilson following the First World War, but it did roll out Prohibition forbidding the manufacture and sale of alcohol. The National Football League was formed, the Negro National Baseball League played its first game in Indianapolis, and some pitcher named George Herman Ruth was sold by the Boston Red Sox to the New York Yankees. The Cleveland Indians also watched as shortstop Ray Chapman was killed after being hit in the head by a pitch, an event that would usher in the live ball era and change the game forever.
