    Star of South Africa diamond found

    also in Land and resources

    An 83.5-carat diamond found near the Orange River was sold for a large sum and publicized in London, proving South Africa held commercially significant diamond deposits. The find triggered a much larger wave of prospectors heading inland.

    Britain annexes Griqualand West

    also in Land and resources

    The British Crown annexed the diamond-bearing territory around Kimberley, overriding competing Boer republic and African claims to the land. Colonial administration of the diggings followed, formalizing British control over the diamond fields.

    Cecil Rhodes arrives at the Kimberley diggings

    also in Land and resources

    Cecil Rhodes, an 18-year-old English immigrant, arrived at the diamond diggings and began working claims and running water pumps for other miners. His early profits in Kimberley became the financial base for his later mining and political career.

    Kimberley diamond fields named after Lord Kimberley

    also in Land and resources

    The mining camp at Colesberg Kopje and the surrounding diggings were officially renamed Kimberley, after the British Colonial Secretary, the Earl of Kimberley. By this point the diggings held thousands of small claims worked by both white diggers and black laborers.

    Barney Barnato arrives in Kimberley

    also in Land and resources

    Barney Barnato, a London-born entrepreneur, arrived at the Kimberley diggings and began buying up claims. He would become Cecil Rhodes's chief rival in the consolidation of the diamond fields over the following fifteen years.

    Deepening pits force consolidation of Kimberley claims

    also in Land and resources

    As individual claims were dug deeper, cave-ins, flooding, and the cost of hauling ore up steep pit walls made small-scale digging increasingly unworkable. Wealthier operators began buying out adjoining claims to consolidate mining operations, a process that accelerated through the 1870s and 1880s.

    De Beers Mining Company founded by Cecil Rhodes

    also in Land and resources

    Cecil Rhodes and Charles Rudd formed the De Beers Mining Company, named after the De Beers brothers whose farm sat atop the diamond deposits, to consolidate claims at the De Beers mine. It became the vehicle Rhodes used over the next eight years to buy out rival claim holders.

    Pass laws formalized for African mineworkers in Kimberley

    also in Land and resources

    Colonial authorities and mine owners in Griqualand West extended pass-law requirements to control the movement of African laborers to and from the diamond mines. Workers had to carry documents identifying their employer and permission to travel, restricting their freedom outside the compounds.

  12. new

    Closed compound system introduced for black mineworkers

    also in Land and resources

    Kimberley mine owners, led by De Beers, began confining African laborers to closed compounds for the duration of their contracts, ostensibly to stop diamond theft. Workers lived in fenced barracks, were searched on exit, and had their movements controlled, a system that became the template for compound labor across southern African mining.

    De Beers Consolidated Mines formed, merging Rhodes and Barnato's holdings

    also in Land and resources

    After a bidding war, Cecil Rhodes and Barney Barnato merged their rival companies into De Beers Consolidated Mines, giving the new company control of nearly all diamond production in the Kimberley area. The merger effectively ended the era of open competition among individual claim holders and created a near-total monopoly over South African diamond output.

    British South Africa Company granted royal charter

    also in Land and resources

    Cecil Rhodes obtained a royal charter for his British South Africa Company, empowering it to acquire mineral rights, administer territory, and raise its own police force north of the Limpopo River. Rhodes used profits and prestige from De Beers to finance and legitimize the charter, extending the diamond fortune into a vehicle for territorial expansion.

  17. new

    London Diamond Syndicate formed to control diamond sales

    also in Land and resources

    A syndicate of London diamond merchants agreed with De Beers to buy its entire output at fixed prices and manage the pace at which diamonds reached the market. The arrangement let De Beers regulate global supply without directly running the retail trade, an early version of the single-channel marketing system it would use for the next century.

    British South Africa Company occupies Mashonaland

    also in Land and resources

    The Pioneer Column, organized and funded by Rhodes's British South Africa Company, occupied Mashonaland and raised the company flag at Fort Salisbury. The occupation, financed substantially by De Beers-derived wealth, opened the territory that would become Southern Rhodesia to settler colonization.

    First and Second Matabele Wars

    also in Land and resources

    British South Africa Company forces fought the Ndebele kingdom, using Maxim guns to defeat larger Ndebele forces and seize their land and cattle. A second uprising in 1896-97 was likewise suppressed, cementing company and settler control over what became Southern Rhodesia.

    Jameson Raid

    also in Land and resources, South Africa: a deep history, The Boer War: gold, the camps, and the making of South Africa

    A raiding party led by Leander Starr Jameson, backed by Cecil Rhodes, invaded the Transvaal in a failed attempt to trigger an Uitlander uprising against the Boer government of Paul Kruger. The raid collapsed within days and its failure forced Rhodes to resign as Cape Prime Minister. The episode badly damaged British-Boer relations and is widely seen as a key step toward the Second Anglo-Boer War.

    Siege of Kimberley during the Second Boer War

    also in Land and resources

    Boer forces besieged Kimberley for 124 days, trapping Cecil Rhodes inside the town along with the De Beers mining operations. De Beers workshops were converted to produce an armored train and an artillery piece, nicknamed Long Cecil, for the town's defense until British forces relieved the siege in February 1900.

    Ernest Oppenheimer arrives in Kimberley

    Ernest Oppenheimer, a young diamond buyer from a German-Jewish trading family, arrived in Kimberley to represent the London diamond merchant firm A. Dunkelsbuhler & Co. He began building relationships in the diamond trade that he would later use to challenge De Beers's control.

    Death of Cecil Rhodes

    also in Land and resources

    Cecil Rhodes died at his seaside cottage near Cape Town at age 48. His will established the Rhodes Scholarship and left instructions reflecting his belief in British imperial expansion, and his death left De Beers under the control of the board he had built.

    Diamonds discovered in German South West Africa

    A railway worker found diamonds in the sand near Lüderitz, setting off a rush that revealed extremely rich alluvial diamond deposits along the Namibian coast. German colonial authorities restricted the area, and control of these deposits later passed to companies connected to Ernest Oppenheimer.

    Anglo American acquires major diamond interests in South West Africa

    Anglo American, through related companies, took control of the rich alluvial diamond fields in South West Africa that had been developed under German rule. This gave Oppenheimer a diamond-producing base independent of De Beers, strengthening his position for a future merger.

    Ernest Oppenheimer becomes chairman of De Beers

    After years of buying De Beers shares and negotiating with the company's directors, Ernest Oppenheimer was elected chairman of De Beers Consolidated Mines. The takeover merged Anglo American's diamond interests with De Beers, placing most of the world's diamond production under Oppenheimer family control for the rest of the century.

    Central Selling Organisation established

    also in Land and resources

    De Beers formally organized its marketing arm as the Central Selling Organisation, a single channel through which the great majority of the world's rough diamonds were sold to a limited list of approved dealers. The CSO let De Beers stockpile diamonds and restrict supply to keep prices high, a cartel arrangement that lasted for most of the twentieth century.

    N.W. Ayer launches the 'A Diamond Is Forever' campaign

    also in Land and resources

    De Beers hired the advertising agency N.W. Ayer, and copywriter Frances Gerety coined the slogan 'A Diamond Is Forever' for a campaign built around linking diamonds inseparably to engagement and marriage. The campaign is widely credited with creating the modern expectation that an engagement requires a diamond ring, particularly in the United States, turning a stockpiled commodity into an object of manufactured cultural necessity.

    Apartheid formalized in South Africa, extending mine labor controls nationwide

    also in Land and resources

    The National Party's election victory formalized apartheid, extending pass laws, labor compounds, and racial job restrictions that had originated in the Kimberley and Witwatersrand mines into comprehensive national policy. Historians have described the mining industry's migrant-labor and compound system as a working model that apartheid legislation later generalized across the economy.

    Angolan civil war begins, drawing in diamond-funded factions

    also in Land and resources

    Following independence from Portugal, Angola descended into a civil war between the MPLA government and UNITA rebels that lasted, with interruptions, until 2002. UNITA financed much of its war effort by controlling alluvial diamond fields in the northeast and selling stones into international markets, including through De Beers buying channels for part of the conflict.

    Sierra Leone civil war begins

    also in Land and resources

    The Revolutionary United Front launched an insurgency against the Sierra Leonean government, beginning an eleven-year civil war marked by mass amputations and the use of child soldiers. The RUF financed its campaign chiefly by seizing diamond-mining areas and smuggling rough diamonds out through neighboring Liberia.

    UN Security Council bans purchase of UNITA diamonds

    also in Land and resources

    The UN Security Council adopted Resolution 1173, prohibiting the direct or indirect import of diamonds from Angola not certified by the government, in an effort to cut off UNITA's main source of funding. It was one of the first international measures explicitly targeting conflict diamonds.

    Fowler Report details sanctions-busting diamond networks

    also in Land and resources

    A UN Security Council panel chaired by Canadian ambassador Robert Fowler published a report naming specific governments, arms dealers, and diamond buyers involved in evading sanctions to keep UNITA supplied with weapons in exchange for diamonds. The report increased international pressure for an industry-wide certification system for rough diamonds.

    Kimberley Process talks begin in South Africa

    also in Land and resources

    Southern African diamond-producing states, industry representatives, and NGOs met in Kimberley to negotiate a certification scheme that would keep conflict diamonds out of the legitimate trade. The talks, named after the town, led to a series of negotiations completed over the following two years.

    De Beers ends the Central Selling Organisation single-channel model

    also in Land and resources

    Facing antitrust pressure and competition from independent producers such as Russia's Alrosa and new Canadian mines, De Beers began dismantling the Central Selling Organisation's stockpile-and-control system in favor of a 'Supplier of Choice' model selling to a smaller set of approved clients at set prices. The change ended De Beers's decades-long role as the buyer of last resort for the entire world diamond supply.

  41. new

    Kimberley Process Certification Scheme launched

    also in Land and resources

    The Kimberley Process Certification Scheme took effect, requiring participating countries to certify shipments of rough diamonds as conflict-free and to trade only with other participating members. Critics have since argued the scheme's narrow definition of 'conflict diamond' and weak enforcement have let it miss diamonds tied to state violence and labor abuse outside civil-war contexts.

    De Beers pleads guilty to price-fixing in the United States

    also in Land and resources

    De Beers pleaded guilty to a US federal charge of conspiring to fix prices of industrial diamonds and paid a 10 million dollar fine, ending decades of the company avoiding direct business in the United States to escape antitrust prosecution. The settlement let De Beers finally operate openly in the US retail market.

    Anglo American acquires majority control of De Beers

    Anglo American plc agreed to buy the Oppenheimer family's 40 percent stake in De Beers for about 5.1 billion dollars, raising its holding to 85 percent and ending direct Oppenheimer family control of the company after 82 years. The Botswana government retained the remaining 15 percent through its long-standing partnership with De Beers.
