Isaac and Amy Post, were radical Hicksite Quakers from Rochester, New York, involved in the struggles for abolitionism and women's rights. Among the first believers in Spiritualism, they helped to associate the young religious movement with the political ideas of the mid-nineteenth-century reform movement.
Amy Post became an active and visible member of the Genesee Yearly Meeting of Hicksite Friends (GYM). Post, alongside her husband Isaac, dedicated much of her time to a very progressive group of Quakers who sought to give both men and women the same rights during the meetings of the Society of Friends. In 1837, Amy Post went against the desires of the Society of Friends elders, who disapproved of slavery but distrusted radical abolitionism, and signed her first “worldly” petition against slavery. In 1842, Amy and Isaac Post became two of the founders of the Western New York Anti-Slavery Society (WNYASS).
In 1848, the Posts also left the Genesse Meeting due to pressure from elders to end their abolitionist activities as well as to help form the Yearly Meeting of Congregational Friends (YMCF), which differed greatly from the GYM in several ways. The motto of the Congregational Friends was “common natures, common rights, and a common destiny.” They believed in abolitionist activities, did not allow racial or sex discrimination, and considered that all persons should be regarded morally, legally and politically equal.Amy and Isaac Post in Wikipedia
