The United Nations General Assembly has adopted a landmark resolution declaring the enslavement of Africans during the transatlantic slave trade as “the gravest crime against humanity,” marking a significant moment in global efforts to confront the legacy of slavery.
The resolution, proposed by Ghana and backed by African and Caribbean states, was adopted with 123 votes in favour, while the United States, Israel, and Argentina voted against. A further 52 countries abstained, including the United Kingdom and several European Union member states.
Although General Assembly resolutions are not legally binding, they carry political and moral weight, and the decision is expected to shape ongoing discussions around reparatory justice, historical accountability, and racial inequality.
While addressing the assembly ahead of the vote, Ghana’s President John Mahama framed the resolution to declare the slave trade the gravest crime against humanity as both a recognition of history and a statement of present responsibility.
“Let it be recorded that when history beckoned, we did what was right for the memory of the millions who suffered the indignity of the slave trade and those who continue to suffer racial discrimination,” he said. He added that the adoption of the resolution “serves as a safeguard against forgetting” while confronting the lasting impact of slavery.
The resolution calls on the UN member states to consider issuing formal apologies for their roles in the transatlantic slave trade, which is now officially recognised as the gravest crime against humanity and to contribute to a reparations framework, though it does not specify financial figures or mechanisms.
Ghana’s Foreign Minister, Samuel Okudzeto Ablakwa, emphasised that the initiative is focused on justice rather than direct financial gain.
“We are demanding compensation, and let us be clear, African leaders are not asking for money for themselves. We want justice for the victims and causes to be supported, educational and endowment funds, skills training funds,” he said.
The push for reparations has gained renewed momentum in recent years. The African Union designated 2025 as the year of reparatory justice, while Commonwealth leaders have also called for structured dialogue on the issue.
Historical estimates indicate that between 12 and 15 million Africans were forcibly taken across the Atlantic between the 16th and 19th centuries, with more than two million people dying during the journey. The resolution notes that the consequences of slavery continue to be felt through persistent racial inequalities and economic disparities affecting people of African descent globally.
Support for the resolution was strong among African and Caribbean states, many of which share historical links to the transatlantic slave trade. Delegates repeatedly pointed to the enduring social and economic effects of that history as justification for formal recognition at the international level.
However, opposition from some Western countries highlighted ongoing divisions around the issue of finally recognising the slave trade as the gravest crime against humanity. The United Kingdom acknowledged the historical harm caused but raised concerns about the legal framing of the resolution, arguing that no single historical atrocity should be ranked above others.
The United States similarly rejected the proposal’s approach, stating that it does not recognise a legal basis for reparations tied to actions that were not considered illegal under international law at the time. Its representative also questioned how any reparatory framework would identify beneficiaries.
Despite these divisions, the adoption of the resolution marks a shift in how the international community is formally addressing the legacy of the slave trade. It places the issue more firmly within global institutional discourse, moving it beyond historical acknowledgement into a structured political question.
For Ghana, the vote to declare the enslavement of Africans the gravest crime against humanity reflects years of sustained advocacy rooted in both history and diplomacy. Along its coastline, the forts that once held enslaved Africans remain standing, serving as physical reminders of a system whose effects continue to shape global inequalities.
What this resolution of declaring the transatlantic slave trade the gravest crime against humanity ultimately changes is the language of the conversation. By placing the transatlantic slave trade at the highest level of historical wrongdoing, it sets a new reference point that future debates on reparations and accountability will have to contend with.
