In the mid-1940s, coastal Kenya was gripped by a chilling rumor. People spoke of Watu wa Mumiani or blood collectors believed to abduct locals and drain their blood to make a substance called mumia. Some believed these figures were connected to the colonial government.
Today, historians like Zebulon Dingley, writing in The Journal of African History, argue that we shouldn’t treat this as a literal vampire story. Instead, as Dingley explores in his 2018 study of the 1945 “Mumiani” scares, these rumors reflected the brutal conditions people were living under.
Between 1944 and 1945, over 1,500 Digo men were forced into labor in Taveta. At the same time, famine devastated the region. Land was controlled, labour was forced, and food was scarce. When people feel exploited and abandoned, trust collapses, and in that vacuum stories grow.
It raises an uncomfortable question- when societies face crisis like hunger, unemployment, environmental disasters, or governments that feel against the very people they are meant to serve, how do people make sense of it? History sometimes reveals how people explain power when it stops protecting them.
What do you think the Watu wa Mumiani story was really about?
