Accoring to the 2008 Forbes International Billionaire List, Aliko Dangote, with a net worth of $3.3 billion is the richest black person in the world, over taking Oprah Winfrey who was listed as the only black billionaire for three straight years. South African gold magnate, Patrice Motsepe , was also listed with a net worth of $2.4 billion. Aliko Dangote and Motseps are the first black Africans to ever appear on the Forbes internationl rich list, however, Mobutu, the Congolese president, and Sani Abacha, the Nigerian military leader, were probably billionaires when they were alive but Forbes could never confirm this (according to Forbes magazine's Kerry Dolan).
