Because of the large-scale conquests of the Ngunis in the 1820s a lot of the Ndau ancestry evolved to include the Nguni bloodline and ancestry. This is evident in the wealth of Nguni words in the Ndau language, Nguni names and surnames. In the 1820s, during a period of severe drought, northern Nguni armies particularly the (Zulu, Swazi, Ndwandwe,Khumalo and Ndebele) people who speak related Bantu languages and inhabit southeast Africa from Cape Province to southern Mozambique, began to migrate to Mozambique from what is now South Africa. One Nguni chief, Nxaba, established a short-lived kingdom inland from Sofala, but in 1837 he was defeated by Soshangane, a powerful Nguni rival. Eventually Soshangane established his capital in the highlands of the middle Sabie River in what is present day Zimbabwe. The Nguni-Shangaans established the Gaza-kingdom in southern Mozambique and subjugated many of the Ndau people who were already living in that area. This history shows that the Nguni invaders had slain a lot of the Ndau men and taken their wives. Due to this, a lot of the "Ndau people" have a lineage with Nguni influences. This was further cemented by the intermarriages between the Nguni and Ndau. The more appropriate term to describe the resultant group including the modern Ndau is Shangaan. The Ndau culture also evolved to include Nguni practices in the same that many Nguni words became part of the Ndau language.
