Why did settler rule last so long in southern Africa?

The short answer

• Why settler rule endured. Rhodesia’s quarter-million whites and South Africa’s much larger settler population held land, mines, and political power in a region they considered their only home. A transfer to majority rule therefore seemed to threaten their security and possessions as well as their authority. As in Algeria, settlers resisted a change they feared would cost them everything. Their willingness to endure sanctions and war helps explain why a negotiated handover remained so difficult, even as colonies farther north became independent.
• Rhodesia and sanctions. Rhodesia’s white government made two calculations when it declared independence unilaterally in 1965. It expected Britain to shrink from using force against fellow whites, and it expected to find ways around sanctions. Britain did not intervene militarily; trade through South Africa and Portuguese Mozambique, along with breached embargoes, kept the regime supplied. Sanctions did not bring it down during the fifteen years that followed. Their pressure accumulated nevertheless, and guerrilla war and the loss of the Portuguese buffer in 1975 made governing and sustaining the economy increasingly difficult.
• The bargain at Lancaster House. By 1979, guerrilla pressure and sanctions had helped bring Rhodesia’s white rulers to accept majority rule. Lancaster House made that agreement possible by giving them constitutional guarantees: white parliamentary seats were reserved for a period, and land transfers were subject to a willing-buyer, willing-seller clause for ten years. These terms helped end the war and secure a peaceful transfer of power. They also left the colonial distribution of land in place. The grievance behind it would erupt two decades later.
• The battle and negotiations. Fighting in south-east Angola in 1987–88 became the largest battle in Africa since El Alamein. Some historians see the bloody stalemate at Cuito Cuanavale, rather than the victory Pretoria expected, as the military hinge of the regional endgame. South Africa’s army could be checked, and Cuba and Angola entered negotiations in a stronger position. The subsequent linkage deal joined Cuban withdrawal to Namibian independence. Whether South Africa suffered a clear defeat or a check remains disputed; the changed bargaining position is easier to establish.

What it changed

Zimbabwe and the land question. Zimbabwe’s independence under Mugabe was a peaceful transfer achieved after a long war. Lancaster House made it possible, but its ten-year land clause left the colonial distribution intact. Once that protection and the patience behind it expired, the unresolved grievance remained for the new state to confront. Violent seizures followed in 2000, as did economic collapse. The settlement had ended the immediate conflict without settling the land question.

Namibia becomes independent. After 75 years of South African rule and 23 years of war, Namibia became independent through the linkage deal. SWAPO’s Sam Nujoma took office after a UN-supervised transition that became a model. On the map, the second-to-last charcoal territory turns red; South Africa remains. The pressures that helped free Namibia, including the demonstration that apartheid’s state could be checked, now bore on Pretoria itself.

Pressure on Pretoria. The loss of friendly or controlled territory north of South Africa changed Pretoria’s position. Mozambique, Zimbabwe, and Namibia no longer formed a buffer around the apartheid state. Its army had been bloodied abroad; sanctions and capital flight were damaging the economy; and its townships were ungovernable. By 1990 these pressures were converging on a government with fewer regional defenses. The next two chapters follow its reckoning.
