The LDS Church happens to be exceedingly prickly about its short, uncommonly rich history--and no aspect of that history makes the church more defensive than "plural marriage." The LDS leadership has worked very hard to persuade both the modern church membership and the American public that polygamy was a quaint, long-abandoned idiosyncrasy practiced by a mere handful of nineteenth-century Mormons. The religious literature handed out by the earnest young missionaries in Temple Square makes no mention of the fact that Joseph Smith--still the religion's focal personage--married at least thirty-three women, and probably as many as forty-eight. Nor does it mention that the youngest of these wives was just fourteen years old when Joseph explained to her that God had commanded that she marry him or face eternal damnation.

Polygamy was, in fact, one of the most sacred credos of Joseph's church--a tenet important enough to be canonized for the ages as Section 132 of The Doctrine and Covenants, one of Mormonism's primary scriptural texts. The revered prophet described plural marriage as part of "the most holy and important doctrine ever revealed to man on earth" and taught that a man needed at least three wives to attain the "fullness of exaltation" in the afterlife. He warned that God had explicitly commanded that "all those who have this law revealed unto them must obey the same . . and if ye abide not that covenant, then are ye damned; for no one can reject this covenant and be permitted to enter into my glory."

Joseph was murdered in Illinois by a mob of Mormon haters in 1844. Brigham Young assumed leadership of the church and led the Saints to the barren wilds of the Great Basin, where in short order they established a remarkable empire and unabashedly embraced the covenant of "spiritual wifery." This both titillated and shocked the sensibilities of Victorian-era Americans, who tended to regard polygamy as a brutish practice on a par with slavery. In 1856, recognizing the strength of the anti-polygamy vote, Republican candidate John C. Fremont ran for president on a platform that pledged to "prohibit in the territories those twin relics of barbarism--Polygamy and Slavery." Fremont lost the election, but a year later the man who did win, President James Buchanan, sent the U.S. Army to invade Utah, dismantle Brigham Young's theocracy, and eradicate polygamy.

The so-called Utah War, however, neither removed Brigham from power nor ended the doctrine of plural marriage, to the annoyance and bafflement of a whole series of American presidents. An escalating sequence of judicial and legislative challenges to polygamy ensued, culminating in the Edmunds-Tucker Act of 1887, which disincorporated the LDS Church and forfeited to the federal government all church property worth more than $50,000. With their feet held fast to the fire, the Saints ultimately had no choice but to renounce polygamy. But even as LDS leaders publicly claimed, in 1890, to have relinquished the practice, they quietly dispatched bands of Mormons to establish polygamous colonies in Mexico and Canada, and some of the highest-ranking LDS authorities secretly continued to take multiple wives and perform plural marriages well into the twentieth century.

Although LDS leaders were initially loath to abandon plural marriage, eventually they adopted a more pragmatic approach to American politics, emphatically rejected the practice, and actually began urging government agencies to prosecute polygamists. It was this single change in ecclesiastical policy, more than anything else, that transformed the LDS Church into its astonishingly successful present-day iteration. Having jettisoned polygamy, Mormons gradually ceased to be regarded as a crackpot sect. The LDS Church acquired the trappings of a conventional faith so successfully that it is now widely considered to be the quintessential American religion.

Mormon Fundamentalists, however, believe that acceptance into the American mainstream came at way too high a price. They contend that the Mormon leaders made an unforgivable compromise by capitulating to the U.S. government on polygamy over a century ago. They insist that the church sold them out--that the LDS leadership abandoned one of the religion's most crucial theological tenets for the sake of political expediency. These present-day polygamists therefore consider themselves to be the keepers of the flame--the only true and righteous Mormons. In forsaking Section 132--the sacred principle of plural marriage--the LDS Church has gone badly astray, they warn. Fundamentalist prophets bellow from their pulpits that the modern church has become "the wickedest whore of all the earth."
