Brazil has pledged its support for John Dramani Mahama’s campaign at the United Nations to formally recognise the Transatlantic Slave Trade as the gravest crime against humanity.

The endorsement was announced by Brazilian President Luiz Inácio Lula da Silva during talks with Ghana’s Foreign Affairs Minister, Samuel Okudzeto Ablakwa, on the sidelines of the CELAC-Africa Summit in Colombia on Saturday, March 21.

Brazil’s backing is expected to strengthen growing international support for Ghana’s initiative, which aims to advance global discussions on reparatory justice for the historical injustices of slavery.

The support is particularly significant given Brazil’s deep historical ties to Africa and its status as home to the largest population of people of African descent outside the continent.

President Mahama is scheduled to table a landmark resolution at the United Nations General Assembly on March 25, 2026, seeking to formally declare the transatlantic slave trade as the gravest crime against humanity.

Advocates say such recognition would mark a major step toward addressing the enduring legacy of slavery, including its social, economic, and cultural impacts on descendants across the world.

If successful, the move could reshape global discourse on historical accountability and strengthen calls for justice and restitution for affected communities.
