The First Great Awakening, or simply Great Awakening, was a religious revitalization movement that swept the Atlantic region, and especially the American colonies in the 1730s and 1740s, leaving a permanent impact on American religion. Indeed, the First Great Awakening launched the Evangelical Christian movement in America and laid the foundation for the Evangelical successes of the Second Great Awakening of 1800-1830. The leaders were Jonathan Edwards, George Whitefield and Gilbert Tennent, among many others.
