The discovery of gold along the Witwatersrand in 1886 transformed South Africa into the world's leading gold producer by 1914. Yet this economic miracle was built on a foundation that would prove both exploitative and ultimately unsustainable: a continent-wide system of migrant labour that drew hundreds of thousands of Black workers from across southern Africa, housed them in compounds far from their families, and created patterns of underdevelopment that persist to this day.
The Architecture of Exploitation
From the outset, South Africa's gold industry relied on a carefully orchestrated system of labour migration. The Witwatersrand Labour Organisation (WNLA), established in 1900 and later absorbed into The Employment Bureau of Africa (TEBA) in 1977, held monopoly recruitment rights across vast territories. Workers were contracted for 18-month periods with no guarantee of re-employment, housed in ethnically segregated compounds, and systematically prevented from advancing up the skills ladder, barriers that reinforced both racial and economic hierarchies.
The recruitment net cast wide. By 1899, two-thirds of mine labour came from Mozambique, with significant numbers also drawn from the Transvaal and Cape provinces. Over the following decades, this expanded to include workers from up to twenty territories across southern and central Africa, from nearby Lesotho and Swaziland to distant Angola, Zambia, and Tanzania.
Numbers That Tell a Story
The scale of this labour system was staggering. The workforce fluctuated dramatically with global and local events, reaching its peak of approximately 480,000 Black miners in 1987-88. These numbers rose and fell like a seismograph of southern African history, reflecting wars, economic depressions, political upheavals, and the volatile gold price.
The South African War of 1899-1902 devastated employment, reducing the workforce from 90,000 to just 45,000. The failed experiment with Chinese indentured labour from 1904-1910 demonstrated the industry's desperation for cheap workers. The Great Depression, paradoxically, saw employment surge as gold's fixed price made South African mines highly profitable while other economies collapsed.
World War II brought another downturn, followed by recovery driven by the discovery of gold in the Orange Free State in 1946. Political tensions in the 1960s—marked by the Sharpeville massacre and Harold Macmillan's "Winds of Change" speech—temporarily stabilized numbers as capital fled the country. The renaissance came in the 1970s as gold prices soared, leading to the industry's employment peak in the late 1980s.
The Geography of Dependence
Three regions consistently dominated labour supply throughout the century: Lesotho, the former Transkei (now part of the Eastern Cape), and Mozambique. By the 1980s, these three areas alone provided over sixty percent of the total workforce. The dependence was mutual but unequal, while the mines needed workers, entire communities became economically dependent on mine wages.
In Lesotho, remittances from South African mines constituted an estimated 75% of the country's gross domestic product. With only 16% of the land arable and under constant threat of erosion, the small mountain kingdom had few alternatives. Similarly, in the former Transkei, more than half of local GDP in many areas came from absent miners' wages.
The Human Toll
This system exacted an enormous human cost. Villages across the region were stripped of their adult male population, leaving women to manage farms, raise children, and maintain households while men worked thousands of kilometres away. The compounds themselves were sites of high mortality, in 1907, the death rate reached 470 per 100,000 employees annually, primarily from pneumonia, tuberculosis, and other diseases.
The illiteracy and linguistic diversity among workers, deliberately maintained to prevent organization, meant that most miners remained trapped in the lowest-paid, most dangerous jobs. The compound system, with its rigid ethnic segregation and authoritarian control, became a laboratory for the apartheid policies that would later be imposed across South African society.
Political Winds and Economic Realities
From the 1970s onward, political pressures began reshaping the labour system. African leaders like Kenneth Kaunda of Zambia banned their citizens from working in South African mines, while disasters like the 1974 aircraft crash that killed 74 Malawian miners led to temporary recruitment bans. The Chamber of Mines responded by launching a drive to replace foreign workers with South Africans, reducing the foreign component from 37% in 1966 to 16% by 1979.
However, this "localization" coincided with a broader decline in the industry's fortunes. Rising production costs, falling gold prices, increased taxation, and global competition gradually eroded profitability. Between 1985 and 2000, while mine output value increased by over 250%, employment fell by half. The workforce that had peaked at nearly half a million in the late 1980s collapsed to just 180,000 by 1995.
Legacy of Underdevelopment
The migrant labour system's collapse revealed its true cost to the source regions. Communities that had organized their entire social and economic structure around male labour migration suddenly faced mass unemployment. In the Eastern Cape and Lesotho, returning miners found depleted agricultural systems, eroded soils, and few alternative sources of income.
The "development" that mining wages had supposedly brought proved illusory. Instead of building local economies, the migrant system had created chronic dependence while systematically undermining traditional agricultural and social systems. Women, who had carried the double burden of family and farm work throughout the century, now faced even greater hardship as remittances dried up.
The AIDS Crisis: A Final Blow
The HIV/AIDS epidemic added a devastating dimension to the industry's decline. The very mobility that had defined the migrant system, men moving between rural homes and urban compounds, proved a perfect vector for disease transmission. Studies documented increasing numbers of HIV-related cancers among miners, while the epidemic further undermined both individual workers and the broader communities dependent on their earnings.
Lessons from a Century of Extraction
The story of migrant labour in South Africa's gold mines reveals how seemingly economic arrangements can reshape entire societies. What began as a solution to labour shortages became a system that subordinated human development to capital accumulation across multiple countries and generations.
The migrant labour system succeeded in its narrow objective: it provided cheap, controllable labour that helped make South Africa the world's dominant gold producer for much of the twentieth century. But this success came at an enormous social cost, the systematic underdevelopment of vast rural areas, the destruction of family structures, and the creation of patterns of dependency and inequality that outlasted the system itself.
As South Africa grapples with the legacies of apartheid and underdevelopment, the century-long history of migrant labour offers crucial insights. It demonstrates how economic systems that prioritize short-term profits over human development create long-term costs that far exceed any temporary gains. The villages of Lesotho and the Eastern Cape, still struggling with poverty and unemployment decades after the migrant labour system's collapse, stand as monuments to this fundamental truth.
The gold may have made South Africa wealthy, but as historian C.W. de Kiewiet observed, the country was built not just on precious metals but on the availability of cheap Black labour. Understanding this history is essential for anyone seeking to address southern Africa's contemporary challenges, because the patterns established in the compounds and recruitment centres of a century ago continue to shape the region's development trajectory today.
