U.N. Calls African Slave Trade the ‘Gravest Crime Against Humanity,’ but U.S. Is 1 of 3 Countries to Vote Against

On 25 March 2026, the United Nations General Assembly adopted a resolution designating the transatlantic slave trade as “the gravest crime against humanity.” This significant vote coincided with the International Day of Remembrance of the Victims of Slavery and the Transatlantic Slave Trade. Spearheaded by Ghana’s President, John Dramani Mahama, the resolution not only condemned the historic atrocity but also advocated for reparations as part of a broader push for justice and equity to combat systemic racism.

In the vote, 123 member nations expressed support for the resolution. However, it garnered opposition from the United States, Argentina, and Israel, while an additional 52 countries, including the United Kingdom and all 27 European Union member states, chose to abstain.

The resolution elaborated on why the African slave trade was labeled as the gravest crime. It cited its significant impact on world history due to its scale, duration, systemic brutality, and enduring repercussions that continue to affect global society today. The text further aimed to stress the necessity of justice, human rights, and dignity, suggesting that reparations constitute a vital step toward rectifying these historical injustices.

In a statement explaining the U.S. opposition to the resolution, Ambassador Dan Negrea, the U.S. Representative to the U.N.’s Economic and Social Council, articulated concerns about the language and implications of the resolution. He expressed that while the U.S. acknowledges the historical wrongs associated with the transatlantic slave trade, it does not recognize a legal basis for current reparations claims for actions that were not deemed illegal under international law at the time they occurred.

Negrea also raised objections regarding the resolution’s implicit ranking of human rights violations, warning that such hierarchies could diminish the suffering experienced by victims of other atrocities throughout history. He reinforced the country’s commitment to addressing past injustices while cautioning against oversimplified interpretations of comparative suffering.

Echoing the U.S. position, U.K. U.N. Ambassador James Kariuki characterised the slave trade as “abhorrent.” However, he cautioned against establishing hierarchies among historical atrocities, arguing that this would undermine the broader complexities of different historical events and the distinct suffering experienced by various communities.

The EU, represented by Cyprus’ deputy U.N. ambassador Gabriella Michaelidou, also expressed similar concerns, stating that the language used in the resolution could perpetuate an inaccurate narrative of historical events. She emphasised that the concept of a hierarchy of atrocity crimes remains legally problematic and inconsistent with established U.N. practices.

Despite the opposition and abstentions, the resolution calls for a mandatory discussion among U.N. member nations on actions to eliminate systemic racism and promote reparatory justice. It encourages collaborative efforts to ensure equitable development and access to essential services such as education, health care, employment, housing, and a safe environment.

Furthermore, the resolution encourages partnerships with regional entities, including the African Union and the Caribbean Community, to facilitate reconciliation and reparations discourse. This reflects an understanding that addressing the legacy of the transatlantic slave trade is critical not only for historical justice but also for fostering a more inclusive and equitable global society.

The adoption of this resolution signifies a critical step towards recognising the impact of the transatlantic slave trade, not merely as a historical footnote but as an ongoing legacy that continues to shape societal structures today. While opposition remains pronounced among certain nations, many see the call for reparations as an essential aspect of acknowledging and addressing historical wrongs.

As the world grapples with the implications of this significant vote, the path to reparatory justice and the promotion of equity will likely dominate discussions in international forums as nations continue to navigate the complex legacies of their colonial pasts.
