In 1925, the Tennessee State Legislature passed the Butler Act, banning public schools from teaching the Theory of Evolution. With the backing of the American Civil Liberties Union, who wanted to create a test case challenging the constitutionality of the Butler Act, and several notables from Dayton, Tennessee, who wanted to bring press coverage to their obscure town, the Dayton schoolteacher John Scopes admitted to teaching evolution.
At the trial, the defense attempted to introduce expert witnesses testifying that the Theory of Evolution was correct (and thus that the act violated Scopes's academic freedom), but the judge ruled them inadmissible. The result was that the trial ended up dominated by two celebrity lawyers - Clarence Darrow for the defense and William Jennings Bryan for the prosecution - arguing about the merits of the Theory of Evolution (which the judge considered to be completely irrelevant to the case).
Scopes was found guilty and fined $100. The ACLU appealed to the Tennessee Supreme Court, who overturned the conviction on a technicality.
