Henry Louis Mencken was an American journalist, essayist, satirist, cultural critic, and scholar of American English. He commented widely on the social scene, literature, music, prominent politicians, and contemporary movements. His satirical reporting on the Scopes Trial, which he dubbed the "Monkey Trial", also gained him attention. The term Menckenian has entered multiple dictionaries to describe anything of or pertaining to Mencken, including his combative rhetorical and prose style.

The Scopes trial, formally The State of Tennessee v. John Thomas Scopes, and commonly referred to as the Scopes Monkey Trial, was an American legal case from July 10 to July 21, 1925, in which a high school teacher, John T. Scopes, was accused of violating Tennessee's Butler Act, which had made it illegal for teachers to teach human evolution in any state-funded school. The trial was deliberately staged in order to attract publicity to the small town of Dayton, Tennessee, where it was held. Scopes was unsure whether he had ever actually taught evolution, but he incriminated himself deliberately so the case could have a defendant.
