Laura Phillips (University of the Witwatersrand) joins JAH editor Marissa Moorman to discuss the entangled histories of minerals, politics, and capital in South Africa. Phillips interrogates the interplay between these forces by focusing on Ga-Mphahlele, a rural community in the northern platinum belt, over a period spanning from the late 19th century through the emergence of majority rule in 1994. Her analysis deepens existing understandings of the co-constitutiveness of political authority and mineral property, demonstrating how contingent and volatile this relationship could be. The story of platinum in Ga-Mphahlele diverges from better known stories of gold and diamonds, shaped in fascinating ways by geological realities, African land purchasing, property rights, and contests over chiefly authority. Phillips also honors the mentorship and scholarship of the late Philip Bonner. Phillips’s open access article ‘Below the Land Deals: The Making of Mineral Property in Ga-Mphahlele, South Africa, 1880–1994’ appears in Volume 63, Issue 1 of The Journal of African History.
