African leaders have called for slavery reparations from former colonial powers at the 38th AU Summit in Ethiopia.

From the 15th to the 19th century, at least 12.5 million Africans were kidnapped, forcibly transported by mostly European merchants, and sold into slavery.

UN Secretary-General Antonio Guterres said in an address to the summit that the bitter fruit of the transatlantic slave trade and colonial exploitation is having a lasting impact on the continent.

How can Africans and people of African descent secure the justice they're calling for? And what forms could reparations for slavery take?
