Nelson Mandela was 95 when he died at his home in Johannesburg, South Africa, on Dec. 5, 2013. According to CNN, Mandela had a long history of lung issues, having been previously hospitalized for a lung infection in June.
Imprisoned for 27 years by the South African apartheid government, Mandela was released on Feb. 11, 1990. Much of the last few years of his imprisonment was spent in hospitals as he was diagnosed with tuberculosis, just one in a long line of lung ailments that eventually led to his death. A lifelong advocate for democracy and equality, Mandela became South Africa's first democratically elected president on May 10, 1994.
