The call to Make South Africa ungovernable was a political slogan of the anti-apartheid movement in South Africa. It is closely associated with mass mobilisation against apartheid in the latter half of the 1980s. The slogan originated in a series of speeches by African National Congress (ANC) leader Oliver Tambo in 1984 and 1985, but it was adopted inside South Africa by the supporters of the United Democratic Front and associated civic organisations.
The slogan conveyed a rhetorical rejection of illegitimate state authority and a strategic endorsement of mass mobilisation, which the ANC viewed as a prelude to democratic revolution. Critics of the campaign claimed that it legitimised political violence and vigilantism and permanently undermined acceptance of state authority in South Africa.
