Emmanuel Katongole is a professor of peace studies at Notre Dame. He says he sees a lot of connections between his teachings and the legacy of Nelson Mandela.

"He speaks volumes about the journey to peace and what it looks like," Katongole says.  "It's a long road to freedom." 

Katongole's coworker, Father Oliver Williams, worked with Mandela about 20 years ago.  He says while meeting Mandela, he learned a lot about forgiveness.
