Millerites

The Millerites were a mid-nineteenth-century American movement, led by the former farmer William Miller, that expected the visible Second Coming of Christ in the early 1840s, most precisely on October 22, 1844. When the date passed without event, the result was the "Great Disappointment," one of the most documented episodes of failed prophecy in modern history, and the seed of several enduring religious movements.

The calculation

Miller, a Baptist layman, studied the prophecies of Daniel and Revelation and concluded that the "cleansing of the sanctuary" in Daniel 8:14, a period of "2,300 days," should be read as 2,300 literal years beginning with the Persian decree to rebuild Jerusalem (which he dated to 457 BCE). That placed the end at 1843. When 1843 passed, the date was refined to October 22, 1844, based on a different reading of the Jewish calendar. Tens of thousands of followers, across the northeastern and midwestern United States, came to believe the world would end that day.

The Great Disappointment

On October 22, 1844, Millerites gathered on hillsides and rooftops, dressed in white "ascension robes," watching the sky. The date's arithmetic is recorded under the timeline entry. Nothing happened. The psychological and social fallout was severe: some followers were left in financial ruin, having given away or sold their possessions; others experienced profound crisis of faith. Newspapers mocked the movement, and Miller himself was shaken.

What came after

The movement did not simply vanish. Out of the disappointment came new interpretations and new denominations. One group concluded that Christ had indeed begun a "heavenly" ministry on that date (the "investigative judgment" reading), founding the Adventist movement, from which the Seventh-day Adventist Church grew. Another strand, under Ellen G. White, became a major American denomination. The Millerite episode is thus a case study in how a failed date can become not the end of a belief but the birth of one, through reinterpretation.

Why it matters

The Millerites belong in this wiki as the archetypal modern dated-apocalypse. They show the mechanics that would repeat in the Witnesses' 1914 and the 2012 scares: a calculation from scripture, a fixed date, a mass expectation, a non-event, and an adaptive survival. Norman Cohn's study of such movements, in The Pursuit of the Millennium, places the Millerites in a long line of remnant groups who read their own time as the world's last. The Great Disappointment is the moment the pattern became historical fact.
