On 29 April 1972, Tiro made one of the most consequential revolutionary addresses in South African history. Dubbed the Turfloop Testimony, Tiro's anti-apartheid speech saw him and many of his fellow student activists expelled, igniting a series of strikes in tertiary institutions across the country. By the time he went into exile in Botswana, Tiro was president of the Southern African Student Movement (SASM), permanent organiser of the South African Student Organisation (SASO) and a leading Black Consciousness proponent, hailed by many as the 'godfather' of the June 1976 uprisings.
