When the British sought to end the slave-trade in the 19th century, African rulers resisted. The Asante Kingdom, in what is now Ghana, was a major participant in the West African slave trade, including the transatlantic trade. The ancestors of the President of Ghana, John Dramani Mahama, who is LEADING the campaign for reparations from Britain, were probably slave-owners. I am not saying this facetiously; it is what the history suggests (thank you @NigelBiggar)
