The republic's Christian founders emphasized that no faith should have a privileged position in America, and religion should not interfere with government workings.
A century ago, journalists and spectators gathered in Dayton, Tennessee, to witness the infamous "monkey trial."
Local high school science instructor John T. Scopes, 24, was accused of violating a new Tennessee law by teaching Charles Darwin's theory of evolution.
