Under apartheid, white oppression of the black majority was extreme, and South Africa became one of the most highly polarized countries in the world. Confronted by a counter-movement headed by the African National Congress (ANC), the ruling National Party (NP) was eventually pressured into a negotiation process that resulted in the adoption of a democratic constitution. This article outlines how democratization defused polarization, but was to be hollowed out by the ANC’s construction of a “party-state,” politicizing democratic institutions and widening social inequalities. This is stoking political tensions, which, despite societal interdependence, are provoking fears of renewed polarization along class and racial lines.
