While the Ngoni were primarily agriculturalists, cattle were their main goal for raiding expeditions and migrations northward. Their reputation as refugees escaping Shaka is easily overstated; it is thought that no more than 1,000 Ngoni crossed the Zambezi river in the 1830s. They raided north, taking women in marriage and men into their fighting regiments. Their prestige became so great that by 1921, in Nyasaland alone, 245,833 people claimed membership as Ngoni although few spoke the Zulu dialect called Ngoni. The Ngoni integrated conquered subjects into their warfare and organization, becoming more a ruling class than an ethnic group, and by 1906 few individuals were of pure Ngoni descent. Only after Ngoni status began to decline did the tribal consciousness of the component groups began to rise, along with their reported numbers. In the early 1930s the Ngonde, Nyasa, Tonga and other groups once again claimed their original tribal status.
