Born Rolihlahla Dalibhunga Mandela on July 18, 1918 (he was nicknamed "Nelson" by a teacher), Mandela works in his parents' rural village of Qunu, South Africa, tilling fields and herding cattle with elders from the local Tembu tribe. After his father dies in 1930, the then-12-year-old is chosen as a future leader of the tribe because of his intelligence – life, however, has other plans.

MAN OF ACTION
Mandela's activism starts early; in 1940 he's expelled from the University of Fort Hare after organizing a strike to protest limitations placed on the student council. He heads to Johannesburg, where he earns a job at a legal firm, starts working on his law degree and meets and marries his first wife, Evelyn Ntoko Mase, with whom he has four children.

A SECOND MARRIAGE
During his time in Johannesburg, Mandela meets 20-year-old social worker Nomzamo Winnie Madikizela. "I cannot say for certain if there is such a thing as love at first sight," he wrote in his 1994 autobiography. "But I do know that the moment I first glimpsed Winnie Nomzamo, I knew that I wanted to have her as my wife." He divorces Evelyn in 1955 and marries Winnie three years later, welcoming daughters with her in 1958 and 1960.

Mandela doesn't go quietly, however; he disappears underground and forms a military wing of the left-leaning African National Congress, helping to stage bombings on power plants, rail lines and other such targets when civilians aren't present. Eluding authorities for a while, he's eventually captured and, in June 1964, is convicted of sabotage and treason and sentenced to life in prison.

FREE AT LAST
On Feb. 11, 1990, 71-year-old Mandela is freed from prison after serving 27 years. South African president F. W. de Klerk was in part responsible for the decision, after taking office and reversing the ban on the African National Congress and other anti-apartheid organizations. Mandela's release is broadcast live around the world.

A GLOBAL ICON
Three years after his release, Mandela receives a Nobel Peace Prize in conjunction with de Klerk, in recognition of their efforts to avoid a South African civil war, joining forces to calm fears and relieve racial tensions. There is, however, tension at home; Mandela and Winnie separate in 1992 and eventually divorce in 1996.

FEELING THE PEACE
Tied by their activism, Bono and Mandela enjoy a longtime friendship, with the U2 frontman even penning a song, "46664," named after Mandela's prisoner number. But their time together is a little less heavy at the 2000 Laureus Sports Awards in Monaco, where they spread a simple message backstage.

DAYS GONE BY
Hundreds of people congregate outside of Mandela's South Africa hospital room on July 18, 2013, to celebrate the critically ill former president's 95th birthday – and his reportedly improving health. Sadly, it was announced on Dec. 5 that Mandela had passed away. "Let us recall the values for which [he] fought. Let us reaffirm his vision of a society in which none is exploited, oppressed or possessed by another. Let us commit ourselves to strive together sparing neither strength nor courage to build a united, non-racial, non-sexiest, democratic and prosperous South Africa," the nation's president Jacob Zuma said when delivering the news.
