Last year I wrote about the sad state of leadership in Africa and how the five million dollar Ibrahim prize for good governance in Africa was not awarded for four of the last six years. The key requirement that failed was voluntarily leaving office.
Nelson Mandela was a great example of an Afican leader. He grew up within the Zulu royalty but chose to elevate his people rather than himself. He sacrificed 27 years of his life in prison to fight against the unfairness of Apartheid. Then, when elected as leader, sought forgiveness over revenge, progress over corruption, peace over war.
Read this excellent NY Times obituary for his whole remarkable story.
