Elmer Gantry by Sinclair Lewis is a satirical novel that explores religious hypocrisy in early 20th-century America. The story follows Elmer Gantry, a brash, self-serving, and charismatic man who starts out as a college football player and a heavy drinker. Despite his lack of true faith, he becomes a successful evangelical preacher by exploiting people's religious beliefs for personal gain.

Gantry rises through the ranks of American revivalism, aligning himself with various religious movements and charismatic leaders. Though he preaches morality, he is frequently involved in scandalous affairs and unethical behavior. The novel exposes the corruption, showmanship, and moral contradictions within organized religion.

Published in 1927, Elmer Gantry caused significant controversy for its critique of religious institutions, but it remains a powerful commentary on ambition, manipulation, and the misuse of faith.
