("The Crushing") Series of Zulu and other Nguni wars and forced migrations in the early 19th century that changed the demographic, social, and political configuration of southern and central Africa.

Ethnic group was set against ethnic group in an ever-increasing radius, resulting in the creation of large refugee populations as well as the establishment of new kingdoms under the Basuto, Gaza, Ndebele , and Swazi peoples.
