Latter-day Saints believe that the marriage of one man and one woman is the Lord’s standing law of marriage. In biblical times, the Lord commanded some to practice plural marriage—the marriage of one man and more than one woman. 1 By revelation, the Lord commanded Joseph Smith to institute the practice of plural marriage among Church members in the early 1840s. For more than half a century, plural marriage was practiced by some Latter-day Saints under the direction of the Church President. 2 
 
 Latter-day Saints do not understand all of God’s purposes in instituting, through His prophets, the practice of plural marriage. The Book of Mormon identifies one reason for God to command it: to increase the number of children born in the gospel covenant in order to “raise up seed unto [the Lord].”3 
 
 Plural marriage did result in the birth of large numbers of children within faithful Latter-day Saint homes. It also shaped 19th-century Mormon society in many ways: marriage became available to virtually all who desired it; per-capita inequality of wealth was diminished as economically disadvantaged women married into more financially stable households; and ethnic intermarriages were increased, which helped to unite a diverse immigrant population. Plural marriage also helped create and strengthen a sense of cohesion and group identification among Latter-day Saints. Church members came to see themselves as a “peculiar people,” covenant-bound to carry out the commands of God despite outside opposition.4 
 
 The Beginnings of Plural Marriage in the Church 
 
 Polygamy had been permitted for millennia in many cultures and religions, but, with few exceptions, it was rejected in Western cultures. In Joseph Smith’s time, monogamy was the only legal form of marriage in the United States. 
 
 The revelation on plural marriage, recorded in Doctrine and Covenants 132, emerged partly from Joseph Smith’s study of the Old Testament in 1831. Latter-day Saints understood that they were living in the latter days, in what the revelations called the “dispensation of the fulness of times.”5 Ancient principles—such as prophets, priesthood, and temples—would be restored to the earth. Plural marriage, practiced by ancient patriarchs like Abraham, Isaac, Jacob, and Moses, was one of those ancient principles.6 
 
 The same revelation that taught of plural marriage was embedded within a revelation about eternal marriage—the teaching that marriage could last beyond death. Monogamous and plural marriages performed by priesthood power could seal loved ones to each other for eternity, on condition of righteousness.7 
 
 The revelation on marriage stated general principles; it did not explain how to implement plural marriage in all its particulars. In Nauvoo, Joseph Smith married additional wives and authorized other Latter-day Saints to practice plural marriage. The practice was introduced carefully and incrementally, and participants vowed to keep their participation confidential, anticipating a time when husbands and wives could acknowledge one another publicly.

 Plural Marriage and Families in 19th-Century Utah 
 
 Between 1852 and 1890, Latter-day Saints openly practiced plural marriage. Most plural families lived in Utah. Women and men who lived within plural marriage attested to challenges and difficulties but also to the love and joy they found within their families. They believed it was a commandment of God at that time and that obedience would bring great blessings to them and their posterity. Church leaders taught that participants in plural marriages should seek to develop a generous spirit of unselfishness and the pure love of Christ for everyone involved. 
 
 Although some leaders had large polygamous families, two-thirds of polygamist men had only two wives at a time. Church leaders recognized that plural marriages could be particularly difficult for women. Divorce was therefore available to women who were unhappy in their marriages; remarriage was also readily available. Women sometimes married at young ages in the first decade of Utah settlement, which was typical of women living in frontier areas at the time. At its peak in 1857, perhaps one half of all Utah Latter-day Saints experienced plural marriage as a husband, wife, or child. The percentage of those involved in plural marriage steadily declined over the next three decades. 
 
 During the years that plural marriage was publicly taught, not all Latter-day Saints were expected to live the principle, though all were expected to accept it as a revelation from God. Indeed, this system of marriage could not have been universal due to the ratio of men to women. Women were free to choose their spouses, whether to enter into a polygamous or a monogamous union, or whether to marry at all. Some men entered plural marriage because they were asked to do so by Church leaders, while others initiated the process themselves; all were required to obtain the approval of Church leaders before entering a plural marriage.

 Anti-Polygamy Legislation and the End of Plural Marriage 
 
 Beginning in 1862, the U.S. government passed laws against the practice of plural marriage. After the U.S. Supreme Court found the anti-polygamy laws to be constitutional in 1879, federal officials began prosecuting polygamous husbands and wives during the 1880s. Believing these laws to be unjust, Latter-day Saints engaged in civil disobedience by continuing to practice plural marriage and by attempting to avoid arrest by moving to the homes of friends or family or by hiding under assumed names. When convicted, they paid fines and submitted to jail time. 
 
 One of the anti-polygamy laws permitted the U.S. government to seize Church property. Federal officers soon threatened to take Latter-day Saint temples. The work of salvation for both the living and the dead was now in jeopardy. In September 1890, Church President Wilford Woodruff felt inspired to issue the Manifesto. “Inasmuch as laws have been enacted by Congress forbidding plural marriages,” President Woodruff explained, “I hereby declare my intention to submit to those laws, and to use my influence with the members of the Church over which I preside to have them do likewise.”8 
 
 The full implications of the document were not apparent at first. The Lord’s way is to speak “line upon line; here a little, there a little.”9 Like the beginning of plural marriage in the Church, the end of the practice was gradual and incremental, a process filled with difficulties and uncertainties. 
 
 The Manifesto declared President Woodruff’s intention to submit to the laws of the United States, and new plural marriages within that jurisdiction largely came to an end. But a small number of plural marriages continued to be performed in Mexico and Canada, under the sanction of some Church leaders. As a rule, these marriages were not promoted by Church leaders and were difficult to get approved. Either one or both of the spouses who entered into these unions typically had to agree to remain in Canada or Mexico. On an exceptional basis, a smaller number of plural marriages were performed within the United States between the years 1890 and 1904. 
 
 The Church’s role in these marriages became a subject of intense public debate after Reed Smoot, an Apostle, was elected to the U.S. Senate in 1903. At the April 1904 general conference, Church President Joseph F. Smith issued a forceful statement, known as the Second Manifesto, making new plural marriages punishable by excommunication.10 Since President Smith’s day, Church Presidents have repeatedly emphasized that the Church and its members are no longer authorized to enter into plural marriage and have underscored the sincerity of their words by urging local leaders to bring noncompliant members before Church disciplinary councils.

 Conclusion 
 
 Plural marriage was among the most challenging aspects of the Restoration. For many who practiced it, plural marriage was a trial of faith. It violated both cultural and legal norms, leading to persecution and revilement. Despite these hardships, plural marriage benefited the Church in innumerable ways. Through the lineage of these 19th-century Saints have come many Latter-day Saints who have been faithful to their gospel covenants as righteous mothers and fathers; loyal disciples of Jesus Christ; devoted Church members, leaders, and missionaries; and good citizens and prominent public officials. Modern Latter-day Saints honor and respect these faithful pioneers who gave so much for their faith, families, and community.

 Originally published October 2014. ||||| After receiving a revelation commanding him to practice plural marriage, Joseph Smith married multiple wives and introduced the practice to close associates. This principle was among the most challenging aspects of the Restoration—for Joseph personally and for other Church members. Plural marriage tested faith and provoked controversy and opposition. Few Latter-day Saints initially welcomed the restoration of a biblical practice entirely foreign to their sensibilities. But many later testified of powerful spiritual experiences that helped them overcome their hesitation and gave them courage to accept this practice. 
 
 Latter-day Saints believe that monogamy—the marriage of one man and one woman—is the Lord’s standing law of marriage. 1 In biblical times, the Lord commanded some of His people to practice plural marriage—the marriage of one man and more than one woman. 2 Some early members of The Church of Jesus Christ of Latter-day Saints also received and obeyed this commandment given through God’s prophets. 
 
 Although the Lord commanded the adoption—and later the cessation—of plural marriage in the latter days, He did not give exact instructions on how to obey the commandment. Significant social and cultural changes often include misunderstandings and difficulties. Church leaders and members experienced these challenges as they heeded the command to practice plural marriage and again later as they worked to discontinue it after Church President Wilford Woodruff issued an inspired statement known as the Manifesto in 1890, which led to the end of plural marriage in the Church. Through it all, Church leaders and members sought to follow God’s will. 
 
 Many details about the early practice of plural marriage are unknown. Plural marriage was introduced among the early Saints incrementally, and participants were asked to keep their actions confidential. They did not discuss their experiences publicly or in writing until after the Latter-day Saints had moved to Utah and Church leaders had publicly acknowledged the practice. The historical record of early plural marriage is therefore thin: few records of the time provide details, and later reminiscences are not always reliable. Some ambiguity will always accompany our knowledge about this issue. Like the participants, we “see through a glass, darkly” and are asked to walk by faith.3 
 
 The Beginnings of Plural Marriage in the Church 
 
 The revelation on plural marriage was not written down until 1843, but its early verses suggest that part of it emerged from Joseph Smith’s study of the Old Testament in 1831. People who knew Joseph well later stated he received the revelation about that time.4 The revelation, recorded in Doctrine and Covenants 132, states that Joseph prayed to know why God justified Abraham, Isaac, Jacob, Moses, David, and Solomon in having many wives. The Lord responded that He had commanded them to enter into the practice.5 
 
 Latter-day Saints understood that they were living in the latter days, in what the revelations called the “dispensation of the fulness of times.”6 Ancient principles—such as prophets, priesthood, and temples—would be restored to the earth. Plural marriage was one of those ancient principles. 
 
 Polygamy had been permitted for millennia in many cultures and religions, but, with few exceptions, was rejected in Western cultures.7 In Joseph Smith’s time, monogamy was the only legal form of marriage in the United States. Joseph knew the practice of plural marriage would stir up public ire. After receiving the commandment, he taught a few associates about it, but he did not spread this teaching widely in the 1830s.8 
 
 When God commands a difficult task, He sometimes sends additional messengers to encourage His people to obey. Consistent with this pattern, Joseph told associates that an angel appeared to him three times between 1834 and 1842 and commanded him to proceed with plural marriage when he hesitated to move forward. During the third and final appearance, the angel came with a drawn sword, threatening Joseph with destruction unless he went forward and obeyed the commandment fully.9 
 
 Fragmentary evidence suggests that Joseph Smith acted on the angel’s first command by marrying a plural wife, Fanny Alger, in Kirtland, Ohio, in the mid-1830s. Several Latter-day Saints who had lived in Kirtland reported decades later that Joseph Smith had married Alger, who lived and worked in the Smith household, after he had obtained her consent and that of her parents.10 Little is known about this marriage, and nothing is known about the conversations between Joseph and Emma regarding Alger. After the marriage with Alger ended in separation, Joseph seems to have set the subject of plural marriage aside until after the Church moved to Nauvoo, Illinois. 
 
 Plural Marriage and Eternal Marriage 
 
 The same revelation that taught of plural marriage was part of a larger revelation given to Joseph Smith—that marriage could last beyond death and that eternal marriage was essential to inheriting the fulness that God desires for His children. As early as 1840, Joseph Smith privately taught Apostle Parley P. Pratt that the “heavenly order” allowed Pratt and his wife to be together “for time and all eternity.”11 Joseph also taught that men like Pratt—who had remarried following the death of his first wife—could be married (or sealed) to their wives for eternity, under the proper conditions.12 
 
 The sealing of husband and wife for eternity was made possible by the restoration of priesthood keys and ordinances. On April 3, 1836, the Old Testament prophet Elijah appeared to Joseph Smith and Oliver Cowdery in the Kirtland Temple and restored the priesthood keys necessary to perform ordinances for the living and the dead, including sealing families together.13 Marriages performed by priesthood authority could link loved ones to each other for eternity, on condition of righteousness; marriages performed without this authority would end at death.14 
 
 Marriage performed by priesthood authority meant that the procreation of children and perpetuation of families would continue into the eternities. Joseph Smith’s revelation on marriage declared that the “continuation of the seeds forever and ever” helped to fulfill God’s purposes for His children.15 This promise was given to all couples who were married by priesthood authority and were faithful to their covenants. 
 
 Plural Marriage in Nauvoo 
 
 For much of Western history, family “interest”—economic, political, and social considerations—dominated the choice of spouse. Parents had the power to arrange marriages or forestall unions of which they disapproved. By the late 1700s, romance and personal choice began to rival these traditional motives and practices.16 By Joseph Smith’s time, many couples insisted on marrying for love, as he and Emma did when they eloped against her parents’ wishes. 
 
 Latter-day Saints’ motives for plural marriage were often more religious than economic or romantic. Besides the desire to be obedient, a strong incentive was the hope of living in God’s presence with family members. In the revelation on marriage, the Lord promised participants “crowns of eternal lives” and “exaltation in the eternal worlds.”17 Men and women, parents and children, ancestors and progeny were to be “sealed” to each other—their commitment lasting into the eternities, consistent with Jesus’s promise that priesthood ordinances performed on earth could be “bound in heaven.”18 
 
 The first plural marriage in Nauvoo took place when Louisa Beaman and Joseph Smith were sealed in April 1841.19 Joseph married many additional wives and authorized other Latter-day Saints to practice plural marriage. The practice spread slowly at first. By June 1844, when Joseph died, approximately 29 men and 50 women had entered into plural marriage, in addition to Joseph and his wives. When the Saints entered the Salt Lake Valley in 1847, at least 196 men and 521 women had entered into plural marriages.20 Participants in these early plural marriages pledged to keep their involvement confidential, though they anticipated a time when the practice would be publicly acknowledged. 
 
 Nevertheless, rumors spread. A few men unscrupulously used these rumors to seduce women to join them in an unauthorized practice sometimes referred to as “spiritual wifery.” When this was discovered, the men were cut off from the Church.21 The rumors prompted members and leaders to issue carefully worded denials that denounced spiritual wifery and polygamy but were silent about what Joseph Smith and others saw as divinely mandated “celestial” plural marriage.22 The statements emphasized that the Church practiced no marital law other than monogamy while implicitly leaving open the possibility that individuals, under direction of God’s living prophet, might do so.23 
 
 Joseph Smith and Plural Marriage 
 
 During the era in which plural marriage was practiced, Latter-day Saints distinguished between sealings for time and eternity and sealings for eternity only. Sealings for time and eternity included commitments and relationships during this life, generally including the possibility of sexual relations. Eternity-only sealings indicated relationships in the next life alone. 
 
 Evidence indicates that Joseph Smith participated in both types of sealings. The exact number of women to whom he was sealed in his lifetime is unknown because the evidence is fragmentary.24 Some of the women who were sealed to Joseph Smith later testified that their marriages were for time and eternity, while others indicated that their relationships were for eternity alone.25 
 
 Most of those sealed to Joseph Smith were between 20 and 40 years of age at the time of their sealing to him. The oldest, Fanny Young, was 56 years old. The youngest was Helen Mar Kimball, daughter of Joseph’s close friends Heber C. and Vilate Murray Kimball, who was sealed to Joseph several months before her 15th birthday. Marriage at such an age, inappropriate by today’s standards, was legal in that era, and some women married in their mid-teens.26 Helen Mar Kimball spoke of her sealing to Joseph as being “for eternity alone,” suggesting that the relationship did not involve sexual relations.27 After Joseph’s death, Helen remarried and became an articulate defender of him and of plural marriage.28 
 
 Following his marriage to Louisa Beaman and before he married other single women, Joseph Smith was sealed to a number of women who were already married.29 Neither these women nor Joseph explained much about these sealings, though several women said they were for eternity alone.30 Other women left no records, making it unknown whether their sealings were for time and eternity or were for eternity alone. 
 
 There are several possible explanations for this practice. These sealings may have provided a way to create an eternal bond or link between Joseph’s family and other families within the Church.31 These ties extended both vertically, from parent to child, and horizontally, from one family to another. Today such eternal bonds are achieved through the temple marriages of individuals who are also sealed to their own birth families, in this way linking families together. Joseph Smith’s sealings to women already married may have been an early version of linking one family to another. In Nauvoo, most if not all of the first husbands seem to have continued living in the same household with their wives during Joseph’s lifetime, and complaints about these sealings with Joseph Smith are virtually absent from the documentary record.32 
 
 These sealings may also be explained by Joseph’s reluctance to enter plural marriage because of the sorrow it would bring to his wife Emma. He may have believed that sealings to married women would comply with the Lord’s command without requiring him to have normal marriage relationships.33 This could explain why, according to Lorenzo Snow, the angel reprimanded Joseph for having “demurred” on plural marriage even after he had entered into the practice.34 After this rebuke, according to this interpretation, Joseph returned primarily to sealings with single women. 
 
 Another possibility is that, in an era when life spans were shorter than they are today, faithful women felt an urgency to be sealed by priesthood authority. Several of these women were married either to non-Mormons or former Mormons, and more than one of the women later expressed unhappiness in their present marriages. Living in a time when divorce was difficult to obtain, these women may have believed a sealing to Joseph Smith would give them blessings they might not otherwise receive in the next life.35 
 
 The women who united with Joseph Smith in plural marriage risked reputation and self-respect in being associated with a principle so foreign to their culture and so easily misunderstood by others. “I made a greater sacrifice than to give my life,” said Zina Huntington Jacobs, “for I never anticipated again to be looked upon as an honorable woman.” Nevertheless, she wrote, “I searched the scripture & by humble prayer to my Heavenly Father I obtained a testimony for myself.”36 After Joseph’s death, most of the women sealed to him moved to Utah with the Saints, remained faithful Church members, and defended both plural marriage and Joseph.37 
 
 Joseph and Emma 
 
 Plural marriage was difficult for all involved. For Joseph Smith’s wife Emma, it was an excruciating ordeal. Records of Emma’s reactions to plural marriage are sparse; she left no firsthand accounts, making it impossible to reconstruct her thoughts. Joseph and Emma loved and respected each other deeply. After he had entered into plural marriage, he poured out his feelings in his journal for his “beloved Emma,” whom he described as “undaunted, firm and unwavering, unchangeable, affectionate Emma.” After Joseph’s death, Emma kept a lock of his hair in a locket she wore around her neck.38 
 
 Emma approved, at least for a time, of four of Joseph Smith’s plural marriages in Nauvoo, and she accepted all four of those wives into her household. She may have approved of other marriages as well.39 But Emma likely did not know about all of Joseph’s sealings.40 She vacillated in her view of plural marriage, at some points supporting it and at other times denouncing it. 
 
 In the summer of 1843, Joseph Smith dictated the revelation on marriage, a lengthy and complex text containing both glorious promises and stern warnings, some directed at Emma.41 The revelation instructed women and men that they must obey God’s law and commands in order to receive the fulness of His glory. 
 
 The revelation on marriage required that a wife give her consent before her husband could enter into plural marriage.42 Nevertheless, toward the end of the revelation, the Lord said that if the first wife “receive not this law”—the command to practice plural marriage—the husband would be “exempt from the law of Sarah,” presumably the requirement that the husband gain the consent of the first wife before marrying additional women.43 After Emma opposed plural marriage, Joseph was placed in an agonizing dilemma, forced to choose between the will of God and the will of his beloved Emma. He may have thought Emma’s rejection of plural marriage exempted him from the law of Sarah. Her decision to “receive not this law” permitted him to marry additional wives without her consent. Because of Joseph’s early death and Emma’s decision to remain in Nauvoo and not discuss plural marriage after the Church moved west, many aspects of their story remain known only to the two of them. 
 
 Trial and Spiritual Witness 
 
 Years later in Utah, participants in Nauvoo plural marriage discussed their motives for entering into the practice. God declared in the Book of Mormon that monogamy was the standard; at times, however, He commanded plural marriage so His people could “raise up seed unto [Him].”44 Plural marriage did result in an increased number of children born to believing parents.45 
 
 Some Saints also saw plural marriage as a redemptive process of sacrifice and spiritual refinement. According to Helen Mar Kimball, Joseph Smith stated that “the practice of this principle would be the hardest trial the Saints would ever have to test their faith.” Though it was one of the “severest” trials of her life, she testified that it had also been “one of the greatest blessings.”46 Her father, Heber C. Kimball, agreed. “I never felt more sorrowful,” he said of the moment he learned of plural marriage in 1841. “I wept days. … I had a good wife. I was satisfied.”47 
 
 The decision to accept such a wrenching trial usually came only after earnest prayer and intense soul-searching. Brigham Young said that, upon learning of plural marriage, “it was the first time in my life that I had desired the grave.”48 “I had to pray unceasingly,” he said, “and I had to exercise faith and the Lord revealed to me the truth of it and that satisfied me.”49 Heber C. Kimball found comfort only after his wife Vilate had a visionary experience attesting to the rightness of plural marriage. “She told me,” Vilate’s daughter later recalled, “she never saw so happy a man as father was when she described the vision and told him she was satisfied and knew it was from God.”50 
 
 Lucy Walker recalled her inner turmoil when Joseph Smith invited her to become his wife. “Every feeling of my soul revolted against it,” she wrote. Yet, after several restless nights on her knees in prayer, she found relief as her room “filled with a holy influence” akin to “brilliant sunshine.” She said, “My soul was filled with a calm sweet peace that I never knew,” and “supreme happiness took possession of my whole being.”51 
 
 Not all had such experiences. Some Latter-day Saints rejected the principle of plural marriage and left the Church, while others declined to enter the practice but remained faithful.52 Nevertheless, for many women and men, initial revulsion and anguish was followed by struggle, resolution, and ultimately, light and peace. Sacred experiences enabled the Saints to move forward in faith.53 
 
 Conclusion 
 
 The challenge of introducing a principle as controversial as plural marriage is almost impossible to overstate. A spiritual witness of its truthfulness allowed Joseph Smith and other Latter-day Saints to accept this principle. Difficult as it was, the introduction of plural marriage in Nauvoo did indeed “raise up seed” unto God. A substantial number of today’s members descend through faithful Latter-day Saints who practiced plural marriage. 
 
 Church members no longer practice plural marriage.54 Consistent with Joseph Smith’s teachings, the Church permits a man whose wife has died to be sealed to another woman when he remarries. Moreover, members are permitted to perform ordinances on behalf of deceased men and women who married more than once on earth, sealing them to all of the spouses to whom they were legally married. The precise nature of these relationships in the next life is not known, and many family relationships will be sorted out in the life to come. Latter-day Saints are encouraged to trust in our wise Heavenly Father, who loves His children and does all things for their growth and salvation.55

 Originally published October 2014.
– The Mormon church's big revelations didn't stop with its sacred undergarments: In an online essay titled "Plural Marriage in Kirtland and Nauvoo," the church for the first time declares that founder Joseph Smith was a polygamist, with a footnote stating that "careful estimates" put his tally of wives at between 30 and 40. The essay explains that Smith was ordered to take multiple wives by an angel who visited him three times between 1834 and 1842; in the last instance, the angel was armed with a sword and threatened a reluctant Smith. The leader, then married to first wife Emma, took his first plural wife, Fanny Alger, in Kirtland, Ohio. Smith and Alger ultimately separated, and the church relocated to Nauvoo, Ill., where he married many more women. The oldest was 56, and the youngest was 14-year-old Helen Mar Kimball; some were already married, a revelation the New York Times describes as the "biggest bombshell for some." The essay explains that a number of marriages, including that with Kimball, were sealed "for eternity alone," suggesting sexual relations weren't involved (the ones that did involve sex were "for time and eternity"). What did Emma think of all this? Per the essay, she was none too pleased, though at one time she did accept four of Smith's wives into their home. And what was the reasoning behind what the essay describes as the "wrenching trial" of polygamy? Kimball said Smith told her that "the practice of this principle would be the hardest trial the Saints would ever have to test their faith." Two more essays discuss plural marriage in the church's later years; they're part of an effort the church is making to share "reliable, faith-promoting" info about its past, the church's historian tells the Times. (Part of that effort: an explanation of its undergarments.)
