This introduction contextualizes the special issue's articles in the broader continental dynamics. It discusses the Eurocentric bias of the historiography and suggests that the view that Europe was responsible for the legal abolition of slavery in Africa should be nuanced and qualified. Some independent African polities abolished slavery before Europe's colonial occupation. Nowhere did European abolitionists encounter a tabula rasa: African polities had complex jurisdictions, oral or written, which formed the normative background against which slavery's abolition should be studied. To do so, however, it is misleading to imagine abolitionism as a unitary movement spreading globally out of Europe. What happened differed from context to context. Normative systems varied, and so did abolition's legal processes. This introduction examines the dynamics that led to the introduction and implementation of anti-slavery laws in African legal systems. It recenters the analysis of the legal abolition of slavery in Africa around particular African actors, concepts, strategies, and procedures.

On April 26, 1846, Ahmad Bey signed a historic emancipation decree making the Regency of Tunis the first in the modern Islamic world to formally abolish the longstanding institution of slavery. While the decree marked the first of such unprecedented measures, attracting a barrage of compliments from anti-slavery societies around the globe, it conflicted with the local notions of enslaving practices and thus prompted an earnest process of legitimation for the formal abolition of slavery before the Majlis al Shari (Sharia Council for Judicial Ordinance), without which abolition would have remained culturally and politically contentious. The paper will assess the socio-cultural context and the plural Islamic legal framework that informed both Ahmad Bey's argument favoring abolition and the divergent responses and attitudes of the religious establishment toward the abolition decree.

In 1890, Sultan Ali of Zanzibar declared in writing that “we wish by every means to stop the slave trade.” Statements like these, in addition to the actual passing of anti-slavery legislation, call into question the generally accepted scholarly understanding that the sultans of Zanzibar only agreed to pass and enforce anti-slavery legislation because they were under duress from European, mainly British, powers, who negotiated favorable political and economic benefits in return for (gradual) abolition. A close analysis of the sources tells a more complicated story of both collaboration and conflict between the Zanzibari sultans, their subjects, and the British agents. Moreover, each sultan had distinctive political and religious beliefs, as well as individual personal experiences and outlooks. This paper explores the anti-slavery legislation passed under three sultans of Zanzibar: Barghash bin Said (1870–1888) who prohibited the transport of slaves by sea in 1873, Ali bin Said (1890–1893) who passed the Slave Trade Prohibition Decree of 1890, and Hamoud bin Mohammed (1896–1902) who passed the Abolition Decree of 1897. By analyzing draft treaties and correspondence before and after the passing of legislation, this paper argues that the sultans and their advisors were not devoid of ideological interest in ending slavery; and that British agents and explorers in the region were too hastily hailed as abolitionists.

This article draws on a variety of primary sources to first illustrate the rise of African abolitionism in the Fante region in the mid-nineteenth century and then situate local abolitionists in the context of colonial legal abolition in the Gold Coast. When the British abolished slavery in 1874, various Fante groups had been developing local anti-slavery views and strategies closely connected to the evolution of a Fante ethnic identity fashioned against the “barbaric” Asante. Tensions arose between the Fante intelligentsia, which spearheaded local abolitionism, and British colonial elites. The article examines the rise of local abolitionism among the coastal Fante through specific ideas, individuals, and events, and discusses subsequent dynamics in the “first age” (1874–1900) of colonial abolitionism in the Gold Coast. It shows that the 1874 abolition was opposed by members of the Fante anti-slavery movement not—as has been argued—because Fante intellectuals were pro-slavery or opposed to the idea of abolition, but because they held different visions of emancipation and were critical of British abolition laws that, unlike in the West Indies, did not compensate slaveowners.

Slavery and the slave trade were fundamental institutions in Ethiopian history. Their abolition was a protracted process that involved developing, debating, passing, and applying multiple anti-slavery and anti-slave trade edicts and decrees under successive rulers. While slavery existed in various societies that were later integrated in the Abyssinian empire since the second half of the nineteenth century and took different forms based on different legal traditions, this article focuses specifically on the Christian kingdom and its successor empire. It analyzes changes and continuities in legal approaches to slavery and its suppression through consecutive Ethiopian governments starting with a discussion of slavery's regulation in the ancient Christian law code, the Fetha nagast (“The Law of the Kings”). The article then considers how successive Christian emperors developed anti-slavery policies in response to both local and global dynamics.

This article examines ways in which slaves and missionaries used public declarations before witnesses to carve out a distinctive space of legal proceedings in pursuit of emancipation in western Tanzania. This way of pursuing emancipation shows slaves deploying their intellectual creativity and cultural knowledge to shape the German and British colonial legal systems. Interviews provide evidence that these public declarations drew on long-standing practices of oathing in western Tanzanian societies, while administrative sources indicate that oaths had been used in Islamic legal practice. Both mission and administrative sources show that these public declarations became a fairly routine means to facilitate slave emancipation between about 1907 and the 1920s. They were seen as legitimate by both (ex)owners and (ex)slaves, and were welcomed by officials as they mitigated tensions between owners and slaves, and between slave owners and missions. This legal practice was not codified in either the gradualist German-era laws on slavery or the more proactive abolitionist laws enacted by the British. It was a bottom-up innovation, developed in a context in which effective emancipation depended on drawn-out struggles and negotiations over personal autonomy and malleable social norms.
