22 October 1844: the Day Passed

In the early 1840s a former farmer named William Miller convinced tens of thousands of Americans that the Second Coming would fall within the decade, most precisely on 22 October 1844, a date derived from a reading of the "cleansing of the sanctuary" in Daniel 8:14. When the day came, followers gathered on hillsides and rooftops in white "ascension robes," watching the sky.

Nothing happened. The psychological and social fallout was severe: some followers were left in financial ruin, having given away their possessions; newspapers mocked the movement; Miller himself was shaken. The movement itself is described under Millerites. The episode became known as the Great Disappointment, one of the most documented failures of a predicted end in modern history.

What came after is the instructive part. The movement did not vanish. One strand concluded that Christ had begun a "heavenly" ministry on the date (the "investigative judgment" reading), founding the Adventist movement and, under Ellen G. White, the Seventh-day Adventist Church. Another became a major American denomination. The Millerite case is the archetype of the modern dated apocalypse: a calculation from scripture, a fixed date, a mass expectation, a non-event, and an adaptive survival. Norman Cohn traced the same mechanics in medieval millenarianism; the Millerites show them in the newspaper age.

The movement that waited is treated under Modern Manufactured Apocalypticism.

The date itself had a history inside the movement. Miller first preached only "about the year 1843"; it was Samuel Snow who supplied the exact day in the summer of 1844, by way of Karaite calendar reckoning, and the "seventh-month movement" that carried his correction swept up many who had previously resisted fixing a day. The October gathering was therefore not Miller's own schedule but a revision he was persuaded to accept weeks beforehand, which made the disconfirmation harder to absorb: those on the hillsides had watched one date already pass that spring.

The census of belief is also worth recording. Estimates of adherents run between fifty thousand and a hundred thousand across the Northeast, with perhaps double that number sympathetic; the movement sustained at least forty-eight periodicals at its peak, most of them founded by Joshua Himes, whose promotional machinery mattered as much as Miller's exegesis.
