The 2 conflicting sides was Christianity VS Evolution in this time period pretty much everyone was a supporter of Christianity and it was unholy to talk about anything that went against it.A substitute high school teacher John T Scopes apparently taught some evolution. He was then taken to court he claims he didnt actually teach human evolution but he purposely submitted to self incrimination ( to draw publicity) he was then fined 100$ The answer to your question Is Christianity VS Human Evolution
