An admixture of free black community leaders, elite white Americans, Quaker activists, and unfree black laborers would seem to make for a strange set of allies and a disjointed reform movement. Yet this mix of historical actors firmly committed themselves to the idea of antislavery progress; or the belief that, through the agency of reformers, the trajectory of post-Revolutionary and early national America would lead toward emancipation, black uplift, and the dissolution of white prejudice. While first movement abolitionists coalesced around the idea of antislavery progress, the many obstacles they faced informed the shape and scope of their activism. For one, slavery in the Mid-Atlantic was based on racial oppression and longstanding white prejudice toward people of color, facts that would continually haunt the efforts of first movement abolitionists. Second, the American Revolution, which influenced and gave broader purchase to opposing slavery, also made abolitionism problematic. Thus, if the idea of antislavery progress informed the ethos of first movement abolitionists, the roadblocks detailed in this chapter to emancipation galvanized them into action.
