 They were behind the first armed resistances against colonisation in the region, with Muhumusa encouraging their followers not to fear European guns because Nyabinghi would turn the Europeans' bullets into water.Muhumusa's rebellion created a great deal of concern among the European colonisers in the region, and well as the European missionaries who were attempting to spread Christianity, prompting the Germans and British to join forces.On September 29, 1911, they surrounded Muhumusa's forces and, after a short battle, arrested her.
