Nelson Mandela: The Prisoner Who Negotiated Apartheid's End in Secret, Without His Own Movement's Permission

He chose armed struggle, then from a prison cell chose to talk to the regime that jailed him, acting alone and unauthorised, refusing his own release until the government agreed to deal with the ANC itself.

In November 1985 the world's most famous political prisoner lay in a private ward of Volks Hospital in Cape Town, recovering from prostate surgery, when an unexpected visitor walked in: Kobie Coetsee, South Africa's minister of justice, the man in charge of the country's prisons, come unannounced. To Mandela the gesture was unmistakable. "Though I acted as though this was the most normal thing in the world, I was amazed," he later wrote. "The government, in its slow and tentative way, was reckoning that they had to come to some accommodation with the ANC. Coetsee's visit was an olive branch."

The visit planted the seed of the decision that would define the second half of his life. The thing to fix on is what Mandela did next, and what he did not do: he did not tell his comrades. For twenty-one years, since the Rivonia Trial of 1964, he and Walter Sisulu, Govan Mbeki and the others had thought as a collective. Now, held apart from them in an isolation cell at Pollsmoor, he decided to open a channel to the apartheid state on his own, calculating that his four fellow prisoners would veto the move if he consulted them. He sent a message out through his lawyer George Bizos to Oliver Tambo, the ANC president in exile in Lusaka, promising he would commit to nothing without the organisation's approval. With that reassurance dispatched, he reached for the olive branch.

This is the reversal at the centre of Mandela's life, and it is easy to miss because the later iconography makes it look inevitable. The man who had founded the ANC's armed wing, who had stood in a Pretoria courtroom and told a judge he was prepared to die, chose, from a prison cell, to talk to the government that had put him there. He did it without instructions, without permission, and against the instincts of his own side. Then he used his captivity to force that government to the table not with him, but with the movement it had spent decades trying to destroy.

The earlier choice: sabotage, and the speech that dared the judge

To see how startling the 1985 reversal was, go back to the choice that put him in prison. Mandela was not a pacifist by temperament, though the ANC of his youth had been committed to non-violence. By 1961 he had concluded that the state had closed every peaceful door. After "a long and anxious assessment of the South African situation," he and a few colleagues decided that "as violence in this country was inevitable, it would be unrealistic and wrong for African leaders to continue preaching peace and non-violence at a time when the government met our peaceful demands with force." The result was Umkhonto we Sizwe, the Spear of the Nation, formed in November 1961.

What is striking is how narrowly he calibrated the violence. He laid out the reasoning three years later, from the dock at the Rivonia Trial on 20 April 1964, in a statement that lasted the better part of three hours. "I did not plan it in a spirit of recklessness, nor because I have any love for violence," he told the court. "I planned it as a result of a calm and sober assessment of the political situation that had arisen after many years of tyranny, exploitation, and oppression of my people by the whites." Then he walked the judges through the logic that would haunt every later accusation that he was a terrorist: "Four forms of violence were possible. There is sabotage, there is guerrilla warfare, there is terrorism, and there is open revolution. We chose to adopt the first method, and to exhaust it before taking any other decision." Sabotage, he argued, "did not involve loss of life, and it offered the best hope for future race relations," and operatives were ordered from the start that "on no account were they to injure or kill people." The point was to frighten the state into change, not to start a race war that would leave the country in ruins for generations.

The trial turned on a second decision, just as deliberate. Mandela and his co-accused chose not to testify as witnesses, which would have exposed them to cross-examination by the state prosecutor Percy Yutar. Instead he gave a prepared statement from the dock, putting the apartheid system itself on trial. His lawyers begged him to cut the final passage, fearing it would provoke the judge into a death sentence. He refused, adding only the qualifier "if needs be," convinced he would hang regardless and would not trim what he believed. Then he delivered the lines that end his statement in the official court transcript: "During my lifetime I have dedicated myself to this struggle of the African people. I have fought against white domination, and I have fought against black domination. I have cherished the ideal of a democratic and free society in which all persons live together in harmony and with equal opportunities. It is an ideal which I hope to live for and to achieve. But if needs be, it is an ideal for which I am prepared to die." He looked the judge, Quartus de Wet, directly in the eye as he said it. On 11 June 1964, de Wet sentenced him and seven others to life imprisonment rather than death. Mandela later said he believed the speech had "dared" the judge to do so.

The prison that became a school

Eighteen of his twenty-seven years were spent on Robben Island, in a cell eight feet by seven, sleeping on a straw mat, breaking rocks and quarrying limestone in dust and glare that permanently damaged his eyes. The conventional reading of those decades is that they were a black hole, a life suspended. Mandela's authorised biographer, Anthony Sampson, who had known him since 1951, argued the opposite. "The prison years are often portrayed as a long hiatus in the midst of Mandela's political career," Sampson wrote, "but I see them as the key to his development, transforming the headstrong activist into the reflective and self-disciplined world statesman."

The evidence is in Mandela's own hand. On 1 February 1975 he wrote to his wife Winnie, then herself locked up in Kroonstad Prison, a letter that reads less like a consolation than a manual for self-construction. "The cell is an ideal place to learn to know yourself," he told her, "to search realistically and regularly the process of your own mind and feelings." He warned her against measuring a life by "external factors such as one's social position, influence and popularity, wealth and standard of education," and pointed instead to "internal factors," the qualities "within easy reach of every soul": "Honesty, sincerity, simplicity, humility, pure generosity, absence of vanity, readiness to serve others," the "foundation of one's spiritual life." And the line he would return to decades later: "Never forget that a saint is a sinner who keeps on trying."

What he was doing on Robben Island was not only introspection. He was studying his enemy with the patience of a lawyer preparing a case. He learned Afrikaans, the language of his Afrikaner jailers, read their history, mapped their vanities and grievances, and befriended the guards, the sort of men Sampson described as "brutal, near-illiterate," finding in them the human material he would later need. The journalist John Carlin, who reported on the transition, put it bluntly: prison was "a laboratory or school" in which Mandela "quite consciously prepared" for the day he would have to "persuade the white government to cede power rather than to do so by force of arms." Carlin's harder point is that the famous forgiveness was not Gandhian saintliness. Mandela, he observed, "is over and above all else a political leader," a man who had founded an army and who, "had he emerged from prison and judged that the most effective and swiftest way to achieve the liberation of his people was through force of arms and revenge, he would have gone for it." Forgiveness became, in his hands, "a political tool," chosen in a cell because revenge would not win.

It cost him everything he was not allowed to keep. He was refused permission to attend his mother's funeral and the funeral of his eldest son Thembi, killed in a car crash at twenty-four. In his autobiography he offered a self-judgement William Finnegan called "a harsh but not an overblown" one: "my commitment to my people, to the millions of South Africans I would never know or meet, was at the expense of the people I knew best and loved most." Prison let him become the leader the country needed; it did not let him remain much of a father.

The gamble: talking alone, refusing release

By 1985 the calculation inside his cell had shifted. South Africa was burning under a state of emergency; the regime could no longer contain the townships, and the cost of holding him was becoming greater than the cost of dealing with him. Mandela read his move from Pollsmoor to an isolation cell as a signal that the government was finally ready to talk, and he decided to test it.

The secret contacts unfolded over four years in stages so tentative they nearly collapsed at every turn. After Coetsee's hospital visit came meetings at the minister's residence at Savernake, then a working group headed by Niel Barnard, the head of the National Intelligence Service, whose brief was, in Barnard's words, to understand "how Mr Mandela's head worked." Between 1985 and December 1989 Coetsee and Mandela met at least fifteen times; Barnard's committee met the prisoner forty-eight times. The government team spent eighteen months trying to make Mandela abandon the armed struggle, break with the Communist Party, and drop the demand for majority rule as the price of further talks. They failed. Mandela would not concede the cornerstones of the ANC's position in exchange for his own freedom.

The decisive document is one Mandela wrote by hand for a meeting with the state president, P. W. Botha, on 5 July 1989, and it survives in full. He opened by admitting what his comrades did not yet know: "I make this move without consultation with the ANC. I am a loyal and disciplined member of the ANC, my political loyalty is owed primarily, if not exclusively to this organisation and particularly to our Lusaka Headquarters." Then he drew the line that protected the movement from being outflanked by his captivity: "I must stress that no prisoner, irrespective of his status or influence, can conduct negotiations of this nature from prison." He insisted: "The step I am taking should, therefore, not be seen as the beginning of actual negotiations between the government and the ANC. My task is a very limited one, and that is to bring the country's two major political bodies to the negotiating table." And he closed off the regime's easiest exit: "The question of my release from prison is not an issue, at least at this stage of discussions, and I am certainly not asking to be freed."

That was the mechanism. A prisoner, speaking only for himself, offering the government the one thing it could not manufacture from outside, the legitimacy of his name, while refusing to let that name substitute for the organisation. The ANC's exile leadership used his handwritten document as the basis for the Harare Declaration, the blueprint for negotiations that the OAU, the frontline states and the Non-Aligned Movement all endorsed. The agenda was no longer whether to talk to the ANC, but how.

The meeting with Botha went ahead, brief and almost cordial, the state president pouring tea. Mandela used it to press one demand, the release of his comrade Walter Sisulu, and made plain that he was not the man to bargain with: Botha "had to negotiate with the ANC," Mandela later said, "and not with me." Barnard, watching, recalled being "so struck by his presence," by "his alertness, his composure, his bearing, the way he met these people as though he had been a pinstriped leader all his life," and concluded: "I think that was the day I realised this could be the man that would become the President."

The payoff, and the man who refused the halo

The rest compressed fast once the logic held. Botha resigned; F. W. de Klerk took office and, on 2 February 1990, legalised the ANC and unbanned every liberation movement. Nine days later Mandela walked out of Victor Verster Prison and, facing the press for the first time in twenty-seven years, quoted the last sentence of his Rivonia speech. The negotiations that followed, the CODESA talks, the assassinations and the marches and the moments when the whole settlement nearly came apart, ran on the same engine he had built in his cell: a refusal to let either side's extremists set the terms, and a willingness to absorb humiliation to keep the table intact. He shared the Nobel Peace Prize with de Klerk in 1993, was inaugurated as South Africa's first democratically elected president in 1994, and stepped down after one term.

He spent his last active years trying to take the halo off. In 2010 the Nelson Mandela Foundation published Conversations with Myself, drawn from his prison letters, notebooks, desk-calendar jottings and dozens of hours of recorded talk, a book he had nursed for years because the official story had made him a plaster saint. It closes with a correction he had wanted to make for decades. "One issue that deeply worried me in prison," he wrote, "was the false image that I unwittingly projected to the outside world: of being regarded as a saint." Then the line that loops back to the letter he had sent Winnie from a cell thirty-five years earlier: "I was never one, even on the basis of the earthly definition of a saint as a sinner who keeps on trying."

That is the thread to hold onto. The life that gets mistaken for hagiography is a record of a man who kept making hard, unpopular, calculated decisions: who chose sabotage over pacifism when the state left him no other door, then chose talk over arms when the state finally opened one, and who in both cases was willing to act alone and absorb the loneliness that came with it. He did not become a symbol by accident. He became one by refusing, over and over, to take the deal that would have freed his body at the cost of his strategy, and by insisting that the government he was trapped inside negotiate not with the prisoner in front of it, but with the people he would not betray.
