The term Great Awakening can refer to several periods of religious revival in American religious history. Historians and theologians identify three or four waves of increased religious enthusiasm occurring between the early 18th century and the late 19th century. Each of these "Great Awakenings" was characterized by widespread revivals led by evangelical Protestant ministers, a sharp increase of interest in religion, a profound sense of conviction and redemption on the part of those affected, an increase in evangelical church membership, and the formation of new religious movements and denominations.
The Awakenings all resulted from powerful preaching that gave listeners a sense of personal guilt and of their need of salvation by Christ. Pulling away from ritual and ceremony, the Great Awakening made religion intensely personal to the average person by fostering a deep sense of spiritual guilt and redemption, and by encouraging introspection and a commitment to a new standard of personal morality. It brought Christianity to African-American slaves and was an apocalyptic event in New England that challenged established authority. It incited rancor and division between old traditionalists who insisted on the continuing importance of ritual and doctrine, and the new revivalists, who encouraged emotional involvement and personal commitment. It had a major impact in reshaping the Congregational church, the Presbyterian church, the Dutch Reformed Church, and the German Reformed denomination, and strengthened the small Baptist and Methodist denominations. It had little impact on Anglicans, and Quakers. Unlike the Second Great Awakening, which began about 1800 and reached out to the unchurched, the First Great Awakening focused on people who were already church members. It changed their rituals, their piety, and their self-awareness.
The First Great Awakening began in the 1730s and lasted to about 1743, though pockets of revivalism had occurred in years prior, especially amongst the ministry of Solomon Stoddard, Jonathan Edwards's grandfather. Edwards's congregation was involved in a revival later called the "Frontier Revivals" in the mid-1730s, though this was on the wane by 1737. But as American religious historian Sydney E. Ahlstrom noted, the Great Awakening "was still to come, ushered in by the Grand Itinerant", the great British Evangelist George Whitefield. Whitefield arrived in Georgia in 1738, and returned in 1739 for a second visit of the Colonies, making a "triumphant campaign north from Philadelphia to New York, and back to the South." In 1740, he visited New England, and "at every place he visited, the consequences were large and tumultuous." Ministers from various evangelical Protestant denominations supported the Great Awakening. In the middle colonies, he influenced not only the British churches, but the Dutch and Germans.
