Which event is closely associated with the term "Great Disappointment"?

The term "Great Disappointment" is closely associated with the prediction of Christ's coming in 1844. This event arose from the 19th-century Millerite movement, led by William Miller, who interpreted biblical prophecies and calculated that Christ would return on October 22, 1844. When this date passed without the expected Second Coming, many followers experienced profound disappointment, leading to a significant crisis of faith for many in the movement.

This pivotal moment had lasting effects, ultimately contributing to the formation of the Seventh-day Adventist Church as a distinct religious group. The experience shaped the theology and identity of the church, especially regarding eschatology, or teachings on the end times.
