Birth of the Movement. The modern American abolition movement emerged in the early 1830s as a by-product of religious revivalism popularly known as the Second Great Awakening. Revivalistic tenets led abolitionists to see slavery as the product of personal sin and to demand emancipation as the price of repentance.
