in 1840, garrison's promotion of woman's rights within the anti-slavery movement was one of the issues that caused some abolitionists, including new york brothers arthur tappan and lewis tappan, to leave the aas and form the american and foreign anti-slavery society, which did not admit women. in june of that same year, when the world anti-slavery convention meeting in london refused to seat america's women delegates, garrison, charles lenox remond, nathaniel p. rogers, and william adams refused to take their seat as delegates as well, and joined the women in the spectator's gallery. the controversy introduced the woman's rights question not only to england, but also to future woman's rights leader elizabeth cady stanton, who attended the convention as a spectator, accompanying her delegate-husband, henry b. stanton.
