Which act did the ACLU challenge in the famous Scopes Monkey Trial of 1925?

In the famous Scopes Monkey Trial of 1925, the American Civil Liberties Union (ACLU) challenged a state law that prohibited the teaching of evolution in public schools. This law was rooted in the beliefs of Christian fundamentalism, which advocated for a literal interpretation of the Bible and opposed the teaching of Darwin's theory of evolution. The trial showcased the conflict between science and religion in American schools and highlighted issues of academic freedom and the separation of church and state.

The ACLU's involvement was primarily focused on defending John T. Scopes, a teacher accused of violating this law by teaching evolution. The case became a significant legal battle emblematic of the broader cultural clash during that era and set a precedent for discussions surrounding educational content and religious influence in public education.
