19th century U.S. social activist contemporaries Elizabeth Cady Stanton, Susan B. Anthony, and Sojourner Truth are publicly memorialized as women’s rights pioneers. These figures’ historical proximity presents an instructive case to explore the epistemological and political stakes of claiming “woman” as a category of aggrievement and its sharp contours of race and citizenship status. To this end, I perform a textual analysis of “Declaration of Sentiments” (1848) by Elizabeth Cady Stanton, “Declaration of Rights of the Women of the United States” (1876) by Susan B. Anthony, and “Ain’t I a Woman?” (1851) by Sojourner Truth. This article reimagines U.S. women’s rights histories by introducing a conceptual toolkit that interlaces feminist and social epistemology with social movement theory.
