As Commonwealth leaders convene in Antigua for their annual summit, debates over calls for British reparations for transatlantic slavery are expected to intensify. Earlier this year, the United Nations General Assembly adopted a resolution spearheaded by Ghana’s President John Mahama, describing the transatlantic slave trade as “the gravest crime against humanity” and urging reparations as a necessary measure to address historical injustices. Guyana’s President Mohamed Irfaan Ali echoed these sentiments last month, asserting that Britain “benefited tremendously from the darkest days of human history.”

However, some scholars and commentators challenge the basis for reparations on historical, moral, and political grounds. David Eltis, a leading historian of the slave trade, contends that the economic benefit Britain derived from transatlantic slavery was modest, with its impact on Britain’s industrial economy described as “small” and on Liverpool—its largest slave-trading port in the mid-18th century—as “trivial.” Nobel laureate Joel Mokyr supports this assessment, emphasizing that the economic contribution of slavery to Britain was limited.

Transatlantic slavery, while profoundly unjust, was part of a broader historical context in which slavery and slave trading were widespread globally, practiced across continents by diverse groups. Historical records indicate that Africans and Arabs played significant roles in African slave trading long before and alongside European involvement. Estimates suggest that approximately 34.5 million Africans were enslaved and exported via the Atlantic, Sahara, Mediterranean, and Indian Ocean routes combined. British involvement accounted for roughly 9 percent of this trade.

In 1804, there were an estimated 45 million individuals in chattel slavery worldwide, with the British West Indies accounting for only about 1.7 percent. Other regions, such as northern Nigeria, reportedly held several million slaves during the mid-19th century under the Fulani, while Arab trade routes supplied tens of thousands of slaves annually, often under brutal conditions.

Critics of the reparations demand also emphasize that Britain was the first major power to abolish both the slave trade in 1807 and slavery itself in subsequent decades. The nation subsequently took an active role in global efforts to suppress slavery in places such as Brazil, Africa, and Australasia. Given this history, some argue that singling out Britain for reparations is disproportionate and overlooks broader historical complexities.

Observers suggest that, rather than engage in reparations debates, Commonwealth leaders use the summit to acknowledge the enduring human suffering caused by slavery while highlighting Britain’s early abolitionist efforts. A constructive focus, they argue, would be to promote collaborative actions against contemporary forms of slavery prevalent in countries including Mauritania, Mali, Niger, Sudan, and Libya. This approach may better serve the Commonwealth’s agenda by addressing present-day challenges without becoming entangled in divisive historical disputes.
