In the mid-1920s, the powerful warlords of Ethiopia were coming to the realisation that a young man of the nobility named Haile Selassie, also known as Ras Tafari, was outcompeting them all and nearing the point where he could proclaim himself their leader, unifying the country for the first time in decades.
Most of his rivals could not understand how this wispy, quiet, mild-mannered man had been able to take control. Yet in 1927, Selassie summoned the warlords, one at a time, to come to Addis Ababa to declare their loyalty and recognise him as leader.
