Shortly after the film was made, the UN withdrew from the Congo after running out of money, and Tshombe became the country’s premier. However, he was treated as a pariah by Africa’s left-wing establishment, who considered him an agent of “neocolonialists.” In 1964, when he flew to Egypt to attend the Cairo Conference of Nonaligned Nations, Egypt’s president Gamal Abdel Nasser placed him under house arrest for the duration of the conference.
In 1965, Tshombe was overthrown in a coup d’etat led by “Diamond Joe” Mobutu, who set up a kleptocracy that ruled for more than three decades. Meanwhile, in 1967, a plane carrying Tshombe was hijacked to Algiers, where he was imprisoned by the left-wing dictatorship of Houari Boumédienne. He died there two years later.
Excellent postscript. Thanks you.
