Inherit the Wind by Jerome Lawrence and Robert E. Lee, is a dramatized version of the famous Scopes "Monkey" Trial of 1925. The plot is that a town passes a law, forbidding teaching anything that goes against what is said in the Book of Genesis. The law was designed to attack the teaching of Darwinism. The big contenders are Mathew Harrison Brady, a christian speaker, and Henry Drummond a very libertarian defense attorney. A very good read.

Also later turned into a movie starring Spencer Tracy and Fredric March; directed by Stanley Kramer. Luckily, the movie stayed very close to the original play.
