[1] It was instituted on 6 December 2002, and is granted by the President of South Africa to foreign citizens who have promoted South African interests and aspirations through co-operation, solidarity, and support.
The order is named after the late Oliver Tambo, who was the African National Congress's president-in-exile for many years.
Recipients are also presented with a carved wooden walking stick, which has a serpent wound around the shaft and a spoon-shaped head displaying the badge of the order and the national arms.
The walking stick symbolises support and solidarity, and a commitment to stand by the recipient in return.
On 28 January 2008, New Zealand anti-apartheid activist John Minto created a controversy over his letter to former South African President Thabo Mbeki after being nominated for the award, saying that he would refuse, on principle, to accept any award from the ANC.
