Charles Grandison Finney (1792–1875), often called "America's foremost revivalist," was a major leader of the Second Great Awakening that had a profound impact on the history of the United States.

In its wake, converts generated movements for social reform in morality (temperance, anti-tobacco, anti-prostitution), honoring the Sabbath, the humane treatment of prisoners, the insane and the handicapped, women's rights and the abolition of slavery was where they had their greatest impact.
