Despite being a quintessentially Arab ideology, Nasserism influenced to a degree left-wing movements in other parts of the developing world, particularly Sub-Saharan Africa and Latin America. Under Nasser, the Egyptian government gave support both moral and material to Sub-Saharan liberation movements fighting European imperialism. Nelson Mandela, the former South African President and Leader of the African National Congress, remarked that this support was crucial in helping sustain the morale of such movements, including in South Africa. Similar sentiments have been expressed by Fidel Castro, the former Cuban President, with regard to the Cuban Revolution and Cuba's later adversities with the United States Government. Both men stated that Egypt's resistance under Nasser against the joint British, French and Israeli invasion of Egypt in 1956 proved to be inspirational for their own movements.
