Mandela, who always praised Gandhi for his principles of 'Satya and Ahimsa', at an unveiling of Gandhi Memorial in South Africa in 1993, had said, "The Mahatma is an integral part of our history because it is here that he first experimented with truth; here that he demonstrated his characteristic firmness in pursuit of justice; here that he developed Satyagraha as a philosophy and a method of struggle." "Gandhi is most revered for his commitment to non-violence and the Congress Movement was strongly influenced by this Gandhian philosophy, it was a philosophy that achieved the mobilisation of millions of South Africans during the 1952 defiance campaign, which established the ANC as a mass-based organisation," Mandela had said in his address
