The Seventh-day Adventist Church had its roots in the Millerite movement of the 1830s to the 1840s, during the period of the Second Great Awakening, and was officially founded in 1863. Prominent figures in the early church included Hiram Edson, Ellen G. White, her husband James Springer White, Joseph Bates, and J. N. Andrews. Over the ensuing decades the church expanded from its original base in New England to become an international organization. Significant developments such the reviews initiated by evangelicals Donald Barnhouse and Walter Martin, in the 20th century led to its recognition as a Christian denomination.

Hiram Edson (1806–1882) was a pioneer of the Seventh-day Adventist Church, known for introducing the sanctuary doctrine to the church. Hiram Edson was a Millerite adventist, and became a Sabbath-keeping Adventist. Like all Millerites, Edson expected that the Second Coming of Jesus Christ would occur on October 22, 1844. This belief was based on an interpretation of the 2300 day prophecy which predicted that "the sanctuary would be cleansed" which Millerites took to mean that Christ would return on that day.
