Mfecane

The Mfecane, meaning "the crushing" in Zulu and also known by the Sesotho name Difaqane, was a period of widespread warfare, forced migration and state formation across southern Africa in the early to mid-nineteenth century, roughly the 1810s to the 1840s. It is most closely associated with the rise of the Zulu Kingdom under Shaka, whose military reorganization set off a chain reaction of displacement among neighboring chiefdoms, though historians debate how much of the upheaval originated with Zulu expansion versus drought, the ivory and slave trades, and pressure from Cape Colony's own frontier expansion. The era reshaped the political map of the region, producing new states including the Ndebele, Sotho and Swazi kingdoms and displacing hundreds of thousands of people, and its scale and causes remain a genuinely contested subject in southern African historiography.
