Immediate, Not Gradual Abolition

The pamphlet was written by Elizabeth Heyrick, a British Quaker philanthropist and prolific anti-slavery campaigner. She published the explosive document anonymously at first, though her authorship became widely known later.

Heyrick fiercely argued that the enslavement of human beings was a grave moral sin that must be ended instantly, rather than phased out over decades. This directly confronted the gradualist, heavily compensated emancipation strategies favored by mainstream abolitionists like William Wilberforce.

The 1824 pamphlet radically shifted the Overton window of the British abolitionist movement by popularizing the concept of immediate, uncompensated emancipation. Its massive influence forced the Anti-Slavery Society to officially drop its gradualist approach by 1830.

Heyrick specifically targeted the West India interest because they heavily propagated the myth that slavery was a necessary, slowly reforming economic system. Her pamphlet exposed the horrific daily realities of the colonies to shatter this narrative and demand immediate legislative action.
