The abolition of slavery in the nineteenth and twentieth centuries was a long process. In terms of the economic views of abolitionists, there has been an excessive focus on the economic ideas of liberal abolitionists and their approach to “Civilization, Christianity, and Commerce.” However, there was a “developmental abolitionism” that has received little attention. Afro-American Martin R. Delany and Liberian James S. Payne were writers who approached abolitionism through this developmentalism. They favored more interventionist measures aimed at building the material power and national autonomy of Black nations to undercut the power of slave-using African chiefs, to provide indigenous Africans with employment, and to undermine the profitability of slave-based cotton production in the Americas. They also implicitly and indirectly approached labor scarcity with solutions ranging from promoting labor-saving technology to cultivating national prosperity that would improve emigration to Africa or increase birth rates.

十九世纪和二十世纪废除奴隶制是一个漫长的过程。就废奴主义者的经济观点而言，人们过度关注自由废奴主义者的经济思想及其“文明、基督教和商业”的态度。然而，有一种“发展废奴主义”却很少受到关注。非裔美国人马丁·R·德拉尼和利比里亚人詹姆斯·S·佩恩是通过这种发展主义来探讨废奴主义的作家。他们赞成采取更多干预主义措施，旨在建立黑人国家的物质力量和民族自治权，以削弱使用奴隶的非洲酋长的权力，为非洲土著提供就业机会，并削弱美洲奴隶制棉花生产的盈利能力。他们还含蓄地、间接地解决了劳动力短缺问题，提出了各种解决方案，从推广节省劳动力的技术到培养国家繁荣，以增加非洲移民或提高出生率。
