"The seeds planted by the Paarl thought leadership did not bear much fruit so long as Afrikaners were divided between colonial and republican regimes. ... In spite of many setbacks, Afrikaner leadership gradually attained their nationalist goals... They also re-segregated the white group into Afrikaans-speaking versus the rest. Afrikaans became the premier official language while English was given second-class treatment. The leadership vowed that there was to be no mixing of language, no mixing of cultures, no mixing of religions and no mixing of races."
