This article explores the widespread phenomenon of anti-colonial movements that relied on magical rituals for protection against European weapons. It examines both the beliefs of the magical practitioners themselves, and those of colonizing observers whose fascination with stories of “primitive magic” contributed to their contrasting self-representations as superior beings in possession of technological wonders. North America’s Ghost Dance movement, China’s Boxer Rebellion, and East Africa’s Maji Maji uprising took place on three different continents but occurred almost simultaneously. The cases come from a narrow period of time, roughly 1890 to 1910, during a peak of colonial violence all over the world.
