In the 19th century, preacher William Miller predicted that Jesus would return to Earth and rapture would begin somewhere between 1843 to 1844. After his first prediction failed, he made another one (also in 1844) claiming he miscalculated dates he studied from the Bible. Thousands of followers believed in Miller but when nothing happened chaos broke out in many places, and many lost their faith. The event then became known as The Great Disappointment. Miller still held onto his belief on his deathbed, thinking (in 1849) that the rapture would happen very soon.
