The Jameson Raid was a pivotal moment in the history of South Africa, linking events from the Anglo-Boer War to the declaration of the Union of South Africa in 1910. For more than a century, the failed revolution has been interpreted through the lens of British imperialism, with responsibility laid at the feet of Cecil Rhodes. Yet, the raid was less a serious attempt to overthrow a Boer government than a wild adventure with transnational roots in American filibustering. In The Cowboy Capitalist, renowned South African historian Charles van Onselen challenges a historiography of over 120 years, locating the raid in American rather than British history and forcing us to rethink the histories of at least three nations. Through a close look at the little-remembered figure of John Hays Hammond, a confidant of both Rhodes and Jameson, he discovers the American Old West on the South African Highveld. This radical reinterpretation challenges the commonly held belief that the Jameson Raid was quintessentially British and, in doing so, drives splinters into our understanding of events as far forward as South Africa’s critical 1948 general election, with which the foundations of Grand Apartheid were laid.
