The Tennessee Butler Act prohibited the teaching of evolution in school.
Explanation:
The Butler Act was a Tennessee law promulgated in 1925 prohibiting teachers of public education from denying the origin of Man as written in the Bible. By extension, the law prohibited the teaching of the evolutionary history of the human lineage, although it did not prohibit the teaching of the theory of evolution as long as it was applied only to other animals and plants. It owes its name to John Washington Butler, on the initiative of this law. The law remained in force until 1967.
