In December 1960, while the Ethiopian emperor, Haile Selassie, was out of the country, his Imperial Bodyguard took over the capital Addis Ababa and proclaimed his son the new emperor. We speak to Dr Asfa-Wossen Asserate, the grand nephew of Haile Selassie, about the coup. Dr Asfa-Wossen is the author of King of Kings, a new history of Haile Selassie's rule.
