Former President Barack Obama will speak at an event in South Africa to mark what would have been Nelson Mandela's 100th birthday.
The Nelson Mandela Foundation and the Obama Foundation said Monday the former U.S. president will give a lecture in Johannesburg this July.
The two foundations said Obama's lecture will focus on "creating conditions for bridging divides, working across ideological lines, and resisting oppression and inequality."
Obama has mostly stayed out of the spotlight since he left office. But he has made several appearances on behalf of his foundation.
And he's met with leaders from China, France, Canada and Australia.
About 4,000 people are expected to attend Obama's Mandela lecture.
