Cecil rhodes the 19th century british colonist created huge fortunes by controlling diamond exports from which region of the world

Cecil Rhodes who lived from 1853 to 1902, was a British financier, statesman, and colonist in South Africa. He made a huge fortune by controlling diamond exports from South Africa, Zimbabwe and Sierra Leone. Rhodes strongly believed in the British rights to colonize and to expand its control, so he helped Britain gain control of South Africa. He also colonized the territory now known as Zimbabwe and Rhodesia. In 1888 he organized the diamond-mining company De Beers Consolidated Mines, Ltd. and he became prime minister of Cape Colony in 1890. By 1891, Rhodes' company owned 90 percent of the world’s production of diamonds.
