Other people have been celebrating his demise.History will always judge people differently based on who is writing it. For many in South Africa though, Castro has, and always will, symbolise anti-imperialism.His unwavering support for the freedom of South Africa and his stance against the apartheid regime will ensure his name is recorded in our history books as one of the foremost international supporters of our liberation struggle.I had the opportunity of accompanying him to Robben Island in September 1998. I was struck by both his easy-going nature and the great interest he paid to the history of the prison.In later years, I was reminded of the trip on two specific occasions: when Raul Castro and Barack Obama shook hands at the funeral of Fidel's contemporary, Nelson Mandela; and when I accompanied the recently released "Cuban Five" on a similar tour of the island.Castro came from a generation of leaders who envisioned a more equitable society, based on mutual co-operation, especially between developing nations.His popularity in South Africa was undeniable. It was Castro who received the loudest applause from the audience at the Union Buildings in 1994 as Mandela was sworn in as president. The only other world figure to have come close to receiving that level of welcome was Palestinian leader Yasser Arafat.It is not a surprise that Castro was held in such high esteem, not only by the South African public, but by many others across the African continent. Cuba supported many liberation organisations, often at the loss of Cuban lives.It was Cuba that intervened militarily against apartheid forces in Angola and Namibia.Cuba is also well known for its medical internationalism, as well as for hosting African students at its universities.In his 1998 speech in the South African parliament, Castro stated that some 400,000 Cuban forces "fought together with African soldiers and officers on this continent for national independence or against foreign aggression"."From the African land in which they worked and fought voluntarily and selflessly, they only took back to Cuba the remains of their fallen comrades and the honour of having fulfilled their duty," he said."That is why we know and value the human qualities of the children of Africa much more than those that for centuries colonised and exploited this continent."In the same speech, Castro also called for a more equitable society, highlighting the great rift between rich and poor in South Africa.He described two South Africas: "one that enjoys wellbeing and freedom, the other having been able to conquer freedom but without wellbeing".His analysis some 18 years ago still rings true today. As we remember his legacy, it is this message for a "more generous, more jointly responsible, more humane" society that should continue inspiring us.This is because the constant struggle towards a more just and equitable future is often a difficult one. As Castro himself once said: "A revolution is not a bed of roses. A revolution is a struggle between the future and the past."Ahmed Kathrada is a former Robben Island prisoner and anti-apartheid activist. The foundation in his name aims to deepen non-racialism...
