He was given a suspended sentence for his part in the campaign. Shortly afterwards a banning order confined him to Johannesburg for six months. During this period he formulated the "M Plan", in terms of which ANC branches were broken down into underground cells.
By 1952 Mandela and Tambo had opened the first black legal firm in the country, and Mandela was both Transvaal president of the ANC and deputy national president.
A petition by the Transvaal Law Society to strike Mandela off the roll of attorneys was refused by the Supreme Court.
In the 'fifties, after being forced through constant bannings to resign officially from the ANC, Mandela analysed the Bantustan policy as a political swindle. He predicted mass removals, political persecutions and police terror.
For the second half of the 'fifties, he was one of the accused in the Treason Trial. With Duma Nokwe, he conducted the defence.
When the ANC was banned after the Sharpeville massacre in 1960, he was detained until 1961 when he went underground to lead a campaign for a new national convention.
Umkhonto we Sizwe (MK), the military wing of the ANC, was born the same year. Under his leadership it launched a campaign of sabotage against government and economic installations.
In 1962 Mandela left the country for military training in Algeria and to arrange training for other MK members.
On his return he was arrested for leaving the country illegally and for incitement to strike. He conducted his own defence. He was convicted and jailed for five years in November 1962. While serving his sentence, he was charged, in the Rivonia trial, with sabotage and sentenced to life imprisonment.
A decade before being imprisoned, Mandela had spoken out against the introduction of Bantu Education, recommending that community activists "make every home, every shack or rickety structure a centre of learning".
Robben Island, where he was imprisoned, became a centre for learning, and Mandela was a central figure in the organised political education classes.
In prison Mandela never compromised his political principles and was always a source of strength for the other prisoners.
During the 'seventies he refused the offer of a remission of sentence if he recognised Transkei and settled there.
In the 'eighties he again rejected PW Botha's offer of freedom if he renounced violence.
It is significant that shortly after his release on Sunday 11 February 1990, Mandela and his delegation agreed to the suspension of armed struggle.
Mandela has honorary degrees from more than 50 international universities and is chancellor of the University of the North.
He was inaugurated as the first democratically elected State President of South Africa on 10 May 1994 - June 1999
Nelson Mandela retired from Public life in June 1999. He currently resides in his birth place - Qunu, Transkei.
Nelson Mandela's greatest pleasure, his most private moment, is watching the sun set with the music of Handel or Tchaikovsky playing.
Locked up in his cell during daylight hours, deprived of music, both these simple pleasures were denied him for decades. With his fellow prisoners, concerts were organised when possible, particularly at Christmas time, where they would sing. Nelson Mandela finds music very uplifting, and takes a keen interest not only in European classical music but also in African choral music and the many talents in South African music. But one voice stands out above all - that of Paul Robeson, whom he describes as our hero.
The years in jail reinforced habits that were already entrenched: the disciplined eating regime of an athlete began in the 1940s, as did the early morning exercise. Still today Nelson Mandela is up by 4.30am, irrespective of how late he has worked the previous evening. By 5am he has begun his exercise routine that lasts at least an hour. Breakfast is by 6.30, when the days newspapers are read. The day s work has begun.
With a standard working day of at least 12 hours, time management is critical and Nelson Mandela is extremely impatient with unpunctuality, regarding it as insulting to those you are dealing with.
When speaking of the extensive travelling he has undertaken since his release from prison, Nelson Mandela says: I was helped when preparing for my release by the biography of Pandit Nehru, who wrote of what happens when you leave jail. My daughter Zinzi says that she grew up without a father, who, when he returned, became a father of the nation. This has placed a great responsibility of my shoulders. And wherever I travel, I immediately begin to miss the familiar - the mine dumps, the colour and smell that is uniquely South African, and, above all, the people. I do not like to be away for any length of time. For me, there is no place like home.
Mandela accepted the Nobel Peace Prize as an accolade to all people who have worked for peace and stood against racism. It was as much an award to his person as it was to the ANC and all South Africa s people. In particular, he regards it as a tribute to the people of Norway who stood against apartheid while many in the world were silent.
We know it was Norway that provided resources for farming; thereby enabling us to grow food; resources for education and vocational training and the provision of accommodation over the years in exile. The reward for all this sacrifice will be the attainment of freedom and democracy in South Africa, in an open society which respects the rights of all individuals. That goal is now in sight, and we have to thank the people and governments of Norway and Sweden for the tremendous role they played.
