Charles Finney is often considered the "father of modern revivalism" because he revolutionized the way that religious revivals were conducted in the 19th century by using innovative preaching techniques, emphasizing the importance of personal conversion and individual responsibility, and encouraging women and minorities to participate in religious activities. His ideas and methods had a significant impact on the Second Great Awakening and the development of evangelical Christianity in America.
