# The Great Disappointment of 1844 | World Religions

## Definition

The Great Disappointment of 1844 was the Millerites’ failed prediction that Jesus would return on October 22, 1844. In World Religions, it shows how a failed prophecy can split a movement and create new denominations.

## What It Is

The Great Disappointment of 1844 was the moment when the Millerites, a Protestant revival movement in the United States, expected Jesus Christ to return on October 22, 1844, and that event did not happen. In World Religions, this term usually refers not just to a failed prediction, but to the way a religious community reacts when a hoped-for apocalypse does not come.

The movement came from William Miller’s reading of biblical prophecy, especially the book of Daniel. He and his followers believed they had found a timeline for Christ’s Second Coming, and many people prepared emotionally and spiritually for that date. When nothing happened, the letdown was so intense that the event became known as the Great Disappointment.

What makes this term worth studying is the aftermath. A failed prophecy does not always end a movement. Sometimes it produces debate, reinterpretation, and new branches. Some Millerites abandoned the movement, but others tried to explain the failure by reworking the prophecy or the meaning of the date. That process helped shape later groups, especially Seventh-day Adventism.

This is a classic example of apocalypticism in action. Apocalyptic movements often expect dramatic divine change, usually soon, and they can become very committed to signs, dates, and interpretation of sacred texts. When the expected event does not happen, the group has to decide whether the prophecy was wrong, the timing was misunderstood, or the meaning was more symbolic than literal.

In a World Religions class, you can think of the Great Disappointment as a case study in how religious ideas move from text to belief to community behavior. It shows how scripture, charisma, expectation, and disappointment can combine to produce new forms of religion rather than simply ending a movement.

## Why It Matters

The Great Disappointment matters because it shows how new religious movements can form around interpretation, not just around a brand-new scripture or founder. The Millerites built a timeline from the Bible, and when that timeline failed, the movement had to answer a harder question: what do believers do when their sacred reading does not match reality?

That question comes up again and again in World Religions. You see it in millenarian movements, in groups that revise prophecy after a failed prediction, and in denominations that split over authority and interpretation. The event is a clean example of how religion is lived by communities, not just read in texts.

It also helps you spot the difference between belief, expectation, and organization. A group can keep its faith after a disappointment, but the structure may change. That is why the Great Disappointment is often discussed alongside the rise of Seventh-day Adventism and other offshoots that came out of the Millerite movement.

## Connections

### William Miller

William Miller was the preacher and biblical interpreter whose calculations led to the 1844 prediction. His role matters because the Great Disappointment starts with his authority as a reader of prophecy. If you are tracing the event, Miller is the person whose interpretation gave the movement its timeline and urgency.

### [Millerites](/hs-world-religions/key-terms/millerites)

The Millerites were the followers who expected Christ’s return in 1844. Studying them shows how a religious movement can grow quickly when people share a strong expectation about the end times. They are the community most directly affected by the disappointment, and their reactions explain the movement’s split and survival.

### Seventh-day Adventism

Seventh-day Adventism grew out of some former Millerites who reinterpreted what happened in 1844. This connection shows that a failed prophecy can become the starting point for a new denomination instead of the end of the story. The Great Disappointment is one of the key background events for understanding this tradition.

### [Apocalypticism](/hs-world-religions/key-terms/apocalypticism)

Apocalypticism is the belief that history is moving toward a dramatic, divinely caused end. The Great Disappointment is a textbook example because the Millerites expected a sudden apocalyptic event. The term helps you classify the movement’s mindset, especially its focus on dates, signs, and end-times expectation.

## On the AP Exam

A quiz question or short-response prompt may ask you to identify the Great Disappointment as a failed apocalyptic prediction and explain what happened next. The best move is to name the date, say that Christ did not return as expected, and connect the event to the rise of new groups like Seventh-day Adventism.

If you get a passage or timeline item, look for clues about prophetic interpretation, millennial expectation, or a religious group splitting after a disappointment. In an essay or discussion, you can use it as evidence that failed prophecy does not always destroy a movement. Sometimes it forces believers to reinterpret texts, change leadership, or form a new denomination.

## The Great Disappointment of 1844 vs Second Coming

The Second Coming is the Christian belief that Christ will return, while the Great Disappointment is the failed expectation that he would return on October 22, 1844. One is the doctrine, the other is a specific historical event tied to a prediction that did not come true.
