Under the Banner of Heaven by Jon Krakauer explores the 1984 double murder committed by Mormon Fundamentalist brothers Ron and Dan Lafferty, who claimed divine justification for their crimes. The book intertwines this true-crime narrative with a critical examination of the history and doctrines of Mormonism, particularly its fundamentalist offshoots that practice polygamy and resist modern governance.

Who should read Under the Banner of Heaven?

This book is ideal for true crime enthusiasts, readers interested in religious extremism, and those curious about the historical tensions between the Church of Jesus Christ of Latter-day Saints (LDS) and its radical splinter groups. It appeals to fans of investigative journalism and narratives that dissect the intersection of faith and violence.

Is Under the Banner of Heaven worth reading?

It offers a chilling look at how religious fervor can justify violence, while contextualizing modern fundamentalist movements within broader Mormon history. Critics praise its depth, though some Mormon scholars dispute its accuracy.

How does Under the Banner of Heaven critique religious fundamentalism?

The book argues that fundamentalist ideologies, when divorced from societal oversight, can enable authoritarianism and violence. It highlights how leaders in offshoot Mormon sects wield absolute control—including coercive polygamy—under the guise of divine mandate, often leading to tragic outcomes like the Lafferty murders.

What role does polygamy play in the book?

Polygamy serves as a focal point for Krakauer’s critique of Mormon Fundamentalist communities. He documents cases of underage marriages and systemic oppression of women, contrasting these practices with the LDS Church’s official renunciation of plural marriage in 1890.
