In which state did the Seventh-day Adventist Church originate?

The Seventh-day Adventist Church originated in New Hampshire. This foundational aspect is deeply rooted in the church's history, specifically linked to the Second Great Awakening, which influenced many religious movements during the early 19th century. In the 1840s, key figures such as William Miller, who led the Millerite movement, were part of a religious revival that spread throughout the northeastern United States. After the Great Disappointment in 1844, where many anticipated the second coming of Christ based on Miller’s predictions, several leaders, including James White and Ellen G. White, helped formally establish the Seventh-day Adventist denomination in 1863.

While other states like Ohio and Michigan played significant roles in the growth and development of the church, especially with developing educational and publishing efforts, the actual origin is tied to the movements and meetings that initially took place in New Hampshire. Choosing New Hampshire reflects an understanding of the church's early roots and the historical context in which it was established.
