Operation Vula was a secret domestic programme of the African National Congress (ANC) during the final years of apartheid in South Africa. Initiated in 1986 at the ANC headquarters in Lusaka and launched in South Africa in 1988, its operatives infiltrated weapons and banned ANC leaders into the country, in order to establish an underground network linking domestic activist structures with the ANC in exile. It was responsible for facilitating the only direct line of communication between ANC headquarters and Nelson Mandela, who at the time was imprisoned and was discussing a negotiated settlement with the government on the ANC's behalf. The operation was disbanded in 1990, after its existence had been publicly revealed and eight of its leaders charged under the Internal Security Act with terrorism and plotting an armed insurrection.
