12 July 1843
The plural marriage revelation is dictated at Nauvoo
William Clayton records a revelation on the eternity of the marriage covenant, including plurality of wives. It is not published. George A. Smith later said it was known to perhaps one or two hundred persons.
28–29 August 1852
Plural marriage publicly announced at a special conferencehinge
At a special missionary conference in Salt Lake City, Orson Pratt delivered a prepared discourse defending plural marriage and the 1843 revelation was read publicly for the first time. Pratt argued from modern revelation, the constitution, the promises to Abraham and the claim that monogamy invited immorality.
Why this is a hingeIt converted a private practice into a public doctrine and set the terms of every Mormon defense for the next forty years.
Disputed Whether Pratt spoke extemporaneously, as tradition holds, or from an announcement leaders had been preparing for weeks.
1 July 1862
Morrill Anti-Bigamy Act
Congress made bigamy in the territories punishable by five years and a $500 fine, annulled the Utah legislature's incorporation of the church, and barred it from holding property worth more than $50,000. Enforcement was almost nonexistent during the Civil War and Reconstruction.
6 January 1870
Women organize in the Fifteenth Ward Relief Society hall
Sarah M. Kimball chaired a meeting where leading women drafted resolutions against the pending Cullom Bill and adopted a resolution calling for the right to vote. Eliza R. Snow arrived partway through and told them they should rise up in the dignity of their calling and speak for themselves.
Disputed The published Deseret News minutes omitted the suffrage resolution.
13 January 1870
The Great Indignation Meetinghinge
Between three and five thousand women filled the old adobe tabernacle to protest the Cragin and Cullom bills. Sarah Kimball presided and no men were present except reporters. Similar meetings followed in dozens of settlements across the territory, and newspapers nationwide reprinted the speeches.
Why this is a hingeIt broke the assumption, on which most antipolygamy politics rested, that Mormon women were silent victims waiting to be rescued.
Disputed Attendance figures range from three thousand to five thousand in the accounts held here.
12 February 1870
Utah women given the vote
The all-male territorial legislature passed a woman suffrage bill unanimously and acting governor S. A. Mann signed it. About twenty-five women voted in a Salt Lake City municipal election two days later, making Utah women the first in the nation to cast ballots under an equal suffrage law.
Disputed Whether enfranchisement was primarily a church strategy to enlarge its voting bloc or a result of women's own prior organizing.
June 1874
Poland Act
Congress gave federal judges jurisdiction over antipolygamy prosecutions in Utah and the power to select jurors, stripping the Mormon-dominated probate courts of criminal jurisdiction. Church leaders then arranged a test case to challenge the Morrill Act.
6 January 1879
Reynolds v. United Stateshinge
A unanimous Supreme Court upheld George Reynolds's conviction and the constitutionality of the 1862 act. Chief Justice Waite wrote that laws are made for the government of actions, and while they cannot interfere with mere religious belief and opinions, they may with practices.
Why this is a hingeIt removed the constitutional defense the Saints had relied on and remains a foundation of American free-exercise doctrine.
Disputed Whether the church litigated it as a free-exercise case at all, or primarily as a question of local autonomy.
22 March 1882
Edmunds Act creates the crime of unlawful cohabitation
Congress made cohabiting with more than one woman a misdemeanor, requiring no proof of a marriage ceremony. It disqualified polygamists from juries, office and the vote, and vacated Utah's election machinery in favour of five federally appointed commissioners who added a test oath of their own devising.
Disputed The commission inserted the phrase "in the marriage relation" into the cohabitation clause, words that appear nowhere in the statute.
October–November 1884
Rudger Clawson convicted, the first under the Edmunds Act
Clawson told the court he regretted that the laws of his country should come into conflict with the laws of God, but that when they did he would invariably choose the latter. The judge, who had intended leniency, sentenced him to four years and fines totalling $800.
1 February 1885
John Taylor's last public sermon; leaders go underground
Taylor told the Saints that no man had a right to control his conscience, then went into hiding. Church leaders instituted an organized underground; over the next years nearly every Utah settlement was raided by federal marshals, often at night.
1885
Colonies founded in northern Mexico
The First Presidency established settlements in Chihuahua and Sonora as a refuge, beginning with Colonia Juarez, Colonia Dublan and Colonia Diaz. Mexican federal statutes since 1884 also prohibited marriage where one partner was already married, a fact church leaders knew from the outset.
Disputed Whether the colonies were principally a polygamous refuge or part of a broader pattern of Mormon out-migration; most colonization occurred after 1890.
27 September 1886
A document in John Taylor's hand refuses to revoke the covenant
About 150 words found after Taylor's death declare that everlasting covenants cannot be abrogated. Lorin C. Woolley, one of Taylor's bodyguards, later claimed that Joseph Smith and Jesus Christ appeared that night and that Taylor ordained five men to keep plural marriage alive whatever the church did.
Disputed The document's existence is not in dispute; the visitation and the ordinations rest on Woolley's accounts of 1912 and 1929, which faithful writers say grew in detail after the other named participants had died.
3 March 1887
Edmunds–Tucker Acthinge
The act dissolved the church corporation and the Perpetual Emigrating Fund, directed the attorney general to escheat church property above $50,000, abolished spousal privilege so wives could be compelled to testify, required an antipolygamy oath of voters, jurors and officeholders, and revoked the vote from every woman in Utah.
Why this is a hingeIt converted the campaign from prosecuting individuals into dismantling the institution, and it is the only instance in United States history in which Congress stripped women of voting rights.
Disputed Congress passed the act on 19 February 1887; it became law on 3 March 1887 without President Cleveland's signature. Sources cite either date — the Supreme Court in Late Corporation (1890) says 19 February, Sunstone 61 n.54 gives both.
25 July 1887
John Taylor dies on the underground
Taylor died in hiding, still pursued. Wilford Woodruff, as president of the Twelve, took charge of a church whose property was being escheated and whose leadership was largely in concealment or prison.
19 May 1890
Late Corporation v. United States upholds the escheat
The Supreme Court sustained the dissolution of the church corporation and the forfeiture of its property to the United States, with an exception for buildings used exclusively for worship. The temples were now plainly at risk.
24–25 September 1890
The Manifesto is written and releasedhinge
Woodruff wrote in his journal that he was under the necessity of acting for the temporal salvation of the church. He drafted the statement in the third person, intending signatures from the Presidency and Twelve; George Q. Cannon edited it down by roughly 150 words and it went out as a personal declaration over Woodruff's name alone.
Why this is a hingeThe document that ended public plural marriage was a first-person statement of intention and advice, not a declaration of the First Presidency and Twelve.
Disputed Whether the shortening and the first-person framing were a deliberate legal hedge or simply Woodruff's own preference, and whether several of its retrospective factual claims were accurate.
6 October 1890
The Manifesto sustained in general conferencehinge
Lorenzo Snow moved that the conference accept Woodruff's declaration concerning plural marriages as authoritative and binding, recognizing him as the only man on earth holding the keys of the sealing ordinances. The vote was unanimous. Zina D. H. Young wrote that day that the hearts of all were tried but looked to God and submitted.
Why this is a hingeThe sustaining vote is what made the Manifesto binding on the church rather than a personal statement, and it is the act later printed in the Doctrine and Covenants.
Disputed Later church statements date the Manifesto 26 September 1890 while Snow's motion dates it 24 September.
October 1891
Woodruff testifies that the Manifesto covers cohabitation
Asked before the master in chancery whether existing plural relations should also cease, Woodruff answered that that had been the intention. Restoration of the escheated property depended on such assurances. George Q. Cannon testified the same month that he knew of no plural marriage entered into since the Manifesto.
Disputed Diaries kept by Abraham H. Cannon record private counsel in the same period that men should keep their covenants with their families, which is not what the public testimony said.
1891
Woodruff explains the Manifesto at Brigham City and Logan
He put a question to the Saints: whether it was wiser to continue attempting plural marriage against the laws of the nation and at the cost of the temples, or to submit. He said the Lord had shown him by vision and revelation exactly what would take place, and that he would have gone to prison himself had God not commanded otherwise.
1894
Enabling Act opens the way to statehood
Congress invited Utah to apply a seventh time. In April of the same year, at a meeting of the Presidency and Twelve in the Salt Lake Temple, Woodruff told George Q. Cannon that the day was near when there would be no difficulty in the way of good men securing noble wives; that year the Presidency authorized plural marriages in Canada, Mexico and two Utah temples.
4 January 1896
Utah admitted as a statehinge
The state constitution guaranteed religious toleration and provided that polygamous or plural marriages are forever prohibited. It also restored the vote to women, an issue that became the constitutional convention's most heated debate, with B. H. Roberts arguing against and Orson F. Whitney and Franklin S. Richards for.
Why this is a hingeStatehood was the prize the Manifesto bought, and it moved regulation of plural families from federal to state hands, where enforcement promptly relaxed.
3 November 1896
Martha Hughes Cannon elected to the Utah Senate
Running as a Democrat against a Republican slate that included her husband Angus M. Cannon, she outpolled him and became the first woman state senator in the United States. Two women were elected to the state house and eleven more to county offices the same day.
8 January 1900
Lorenzo Snow states that the Manifesto applies everywhere
After B. H. Roberts was barred from his seat in Congress over his three wives, Snow declared publicly that the church had positively abandoned plural marriage in this and every other state and that no officer had any authority to perform such a marriage. A small number continued to be performed.
20 January 1903
Reed Smoot elected to the U.S. Senate
The Utah legislature chose Smoot, an apostle since 1900 and a monogamist, by 46 votes to 16. The Salt Lake Ministerial Association and Protestant and reform groups petitioned that he not be seated, alleging that the church's leaders still connived at plural marriage.
2–9 March 1904
Joseph F. Smith testifies at the Smoot hearings
The church president was the first witness, testifying on six separate days. He acknowledged cohabiting with five wives and fathering eleven children since 1890, and said he had taken his chances rather than abandon his children and their mothers. Asked about new plural marriages, he distinguished acts sanctioned by the church from acts of individuals.
Disputed Whether Smith's answers were careful legal distinctions or evasions; contemporaries on his own side judged the testimony damaging.
6 April 1904
The Second Manifestohinge
Joseph F. Smith read a statement affirming that no plural marriages had been solemnized with the sanction, consent or knowledge of the church, and announcing that all such marriages were prohibited, with excommunication for any officer or member who solemnized or entered one. It was sustained unanimously.
Why this is a hingeFrancis M. Lyman said the 1890 Manifesto had only given notice that Saints need not enter plural marriage; the 1904 action made it prohibitory, with penalties, worldwide.
Disputed Seymour B. Young's diary records that those who seconded the motion did so "per arrangement," and several seconders had themselves performed or permitted post-Manifesto marriages.
28 October 1905
Taylor and Cowley sign resignations
Apostles John W. Taylor and Matthias F. Cowley, who had continued to marry and to solemnize plural marriages, signed resignations to be used if needed. They were formally dropped from the Quorum of the Twelve at the afternoon session of general conference on 8 April 1906.
Disputed Whether the resignations were a genuine disciplinary act or a political sacrifice to save Smoot's seat; Francis M. Lyman insisted the two men were truly out of harmony with the quorum.
20 February 1907
The Senate lets Smoot keep his seat
The Committee on Privileges and Elections had voted 7 to 5 in June 1906 that Smoot was not entitled to his seat. The full Senate rejected the resolution, 28 for expulsion and 42 against, short of the two-thirds required. Smoot served twenty-six more years.
28 March 1911
John W. Taylor excommunicated
Taylor was cut off for insubordination to the government and discipline of the church. Cowley's trial followed in May; he was deprived of all authority in the priesthood but not excommunicated, his fuller acknowledgements being cited as the reason for the difference.
1929–1935
Mormon fundamentalism organizes
Lorin C. Woolley published a detailed account of the 1886 night and called a priesthood council of six men. After a 1933 First Presidency statement rejecting the claim, the church began excommunicating those who continued to support plural marriage, and adherents began gathering at Short Creek on the Utah–Arizona line.
26 July 1953
The Short Creek raid
Arizona officers and National Guardsmen entered the town, jailed the men and bused women and children away; more than 160 children and their mothers remained in Arizona foster placements for nearly two years. Public revulsion at the operation contributed to a backlash, and nearly all those taken returned.
Today
The revelation stands; the sealing asymmetry remains
Doctrine and Covenants 132 is still canonized and anyone practising plural marriage is excommunicated. Under current handbook policy a living woman may be sealed to only one husband and needs a cancellation to be sealed to another, while a widower may be sealed to a second wife without cancelling the first.
Disputed Whether that asymmetry is a doctrine grounded in D&C 132 or a policy that could be changed, argued at length within faithful venues as well as by critics.
