46664: global campaign for change
Nelson Mandela was sent to prison on Robben Island in 1964; he was the 466th prisoner to arrive that year. He was given the prison number 46664.
Thirty-eight years later, Mandela gave his number to a global HIV/AIDS prevention and awareness campaign as a reminder of the sacrifices he made for a cause he believed in. 46664 (pronounced "four, double six, six four") was established in 2002 as an independent, not-for-profit organisation.
Mandated to engage the world's youth, a series of high-profile concerts was planned - starting with a concert in November 2003 in Cape Town, which saw artists such as Beyoncé, Baaba Maal, Angelique Kidjo, Peter Gabriel, Yvonne Chaka Chaka and the Eurythmics perform.
In the following years, Norway, Spain and the UK also hosted concerts. In 2008, a special tribute concert was held in London in celebration of Madiba's 90th birthday.
'It's in our hands'
At the concert, Mandela told the Wembley Stadium audience, "even as we celebrate, let us remind ourselves that our work is far from complete. Where there is poverty and sickness including Aids, where human beings are being oppressed, there is more work to be done.
"Our work is for freedom for all... it's time for new hands to lift the burdens. It's in your hands now."
The 46664 campaign has broadened its approach to heed Mandela's call, taking up issues of social injustice and to ensure his humanitarian legacy.
