What is now known as the Adventist movement traces its beginning to the 1830s and the preaching of the imminent return of Christ by Baptist preacher William Miller. Miller predicted Christ’s return in 1843, later revised to 1844. When Christ failed to return, believers gathered at a conference in Albany, New York, to consider their future. The amorphous movement took the name Evangelical Adventists and over the next decade several distinct groups began to coalesce and then assume formal organized form, though a variety of otherwise independent evangelists, writers, and periodical publishers continued to exist through the end of the century. Adventists were initially divided by the acceptance of many of sabbatarianism (the belief that Saturday, not Sunday, was the proper day for Christians to gather and worship). Sabbatarians then split over the acceptance of the prophecies of Ellen G. White, whose followers founded the Seventh-day Adventist Church. Among the Adventists who continued to gather for worship on Sunday, a series of new dates were proposed for the second coming, each date provoking the organization of those who accepted it.
