Nelson Mandela was the country bumpkin made good, running away from his rural home as a teenager to become a lawyer in the big city and, later, one of the world’s most famous guerrilla leaders and most lionized political prisoners. After 27 years of incarceration, he was freed in 1990 and, in 1994, elected leader of one of the globe’s newest democracies, South Africa. After a single term, he stepped down in a seamless transition of power, but he has remained a father figure for the nation.
