The former US president will give the annual speech to commemorate Mandela's centennial.
Every year the Nelson Mandela Foundation invites prominent figures to Johannesburg to discuss pressing social matters affecting the global community for its 16th annual Nelson Mandela Lecture. This year, that figure is none other than former US president Barack Obama.
This year's theme is "Renewing the Mandela Legacy and Promoting Active Citizenship in a Changing World." The lecture will focus on"creating conditions for bridging divides, working across ideological lines, and resisting oppression and inequality," said the foundation in a statement.
