Tennessee's Butler Act of 1925 prohibited teaching human evolution in public schools. The American Civil Liberties Union offered to defend any teacher charged under the law, seeking to challenge its constitutionality. Local boosters in Dayton, Tennessee, deliberately arranged for teacher John T. Scopes to be charged in order to draw national attention to their town, even though Scopes was uncertain he had actually taught evolution.
From July 10 to 21, 1925, John T. Scopes stood trial in Dayton, Tennessee, for violating the Butler Act. Former U.S. Secretary of State William Jennings Bryan argued for the prosecution, while renowned defense attorney Clarence Darrow represented Scopes. The proceedings drew massive national press coverage and were broadcast live on radio. Scopes was found guilty and fined $100, though the verdict was subsequently overturned on a technicality.
The trial became a widely recognized symbol of the cultural and intellectual tensions of 1920s America, spotlighting the fundamentalist–modernist controversy over religion and science. It highlighted the growing power of mass media and demonstrated radio's capacity to bring courtroom drama to a national audience. Debates over teaching evolution in public schools continued for decades, shaping legislation and court cases well beyond 1925.
