Answer:
The Butler Act was a law passed in Tennessee in 1925 that prohibited the teaching of evolution in public schools. The law was named after its sponsor, John Washington Butler, a state representative. The law was met with significant opposition from those who saw it as an infringement on academic freedom and the separation of church and state.
Many people cared about the Butler Act because it represented a larger cultural and political battle over the teaching of evolution and the role of religion in public schools.
