Favorable political opportunity structure shifts facilitated black mobilization against apartheid

Evidence

Figure 5.1 indicates that POS became less favorable to South African blacks between 1948 and 1970, but then reversed as independent centers of power, backed by foreign pressure, began to form, political alignments within the regime became more unstable, and influential allies and supporters became more available both domestically and internationally despite the government’s own resistance to new actors and deployment of increasingly heavy-handed repression. Those changes facilitated black mobilization and resistance. By 1990, runs the analysis, all elements of POS were moving decisively toward greater opportunity for previously repressed political actors. — Charles Tilly, Regimes and Repertoires, 630
