The Liberator (newspaper)The Liberator (1831–1865) was a weekly abolitionist newspaper, printed and published in Boston by William Lloyd Garrison and, through 1839, by Isaac Knapp. Religious rather than political, it appealed to the moral conscience of its readers, urging them to demand immediate freeing of the slaves ("immediatism"). It also promoted women's rights, an issue that split the American abolitionist movement. Despite its modest circulation of 3,000, it had prominent and influential readers, including all the abolitionist leaders, among them Frederick Douglass, Beriah Green, Arthur and Lewis Tappan, and Alfred Niger.
