The Seventh-day Adventist Church pioneers were members of Seventh-day Adventist Church, part of the group of Millerites, who came together after the Great Disappointment across the United States and formed the Seventh-day Adventist Church. In 1860, the pioneers of the fledgling movement settled on the name, Seventh-day Adventist, representative of the church's distinguishing beliefs. Three years later, on May 21, 1863, the General Conference of Seventh-day Adventists was formed and the movement became an official organization.
