The Latter Day Saint movement is a religious movement within Christianity that arose during the Second Great Awakening in the early 19th century and that led to the set of doctrines, practices, and cultures called Mormonism, and to the existence of numerous Latter Day Saint churches. Its history is characterized by intense controversy and persecution in reaction to some of the movement's doctrines and practices and their relationship to mainstream Christianity. The purpose of this article is to give an overview of the different groups, beliefs, and denominations that began with the influence of Joseph Smith.

The Second Great Awakening was a Protestant religious revival during the late 18th to early 19th century in the United States. It spread religion through revivals and emotional preaching and sparked a number of reform movements. Revivals were a key part of the movement and attracted hundreds of converts to new Protestant denominations. The Methodist Church used circuit riders to reach people in frontier locations.
