"Patrys" is a monthly children's magazine published in Johannesburg by Voortrekker Press, a political publishing group of the Afrikaner Nationalist Party whose most senior members—including Cabinet Ministers and Prime Ministers—are to be found on the board of directors. The magazine is for white children only and is published only in Afrikaans. Its two editions therefore cover the Afrikaner two-thirds of white South African children between the ages of six and 18.

Early in the 1960s, South Africa's English-language press carried stories of an Afrikaner children's club whose members were encouraged to report their parents to the authorities if they suspected them of being un-South African. On January 30 and February 6, 1966, the Johannesburg "Sunday Express," acting on published reports that young Afrikaners calling themselves "Patry's Detectives" were indiscriminately arresting adult Africans in Johannesburg, published the result of some investigations it had made.
