 Under the leadership of King Zwide, the Ndwandwe nation destroyed the Mthethwa under their king Dingiswayo, and the power vacuum was filled by Shaka Zulu and the Zulu tribe.In a common front against the Ndwandwe, Shaka collected the remains of the Mthethwa and other regional tribes, and survived the first encounter of the Zulu Civil War with Zwide at the Battle of Gqokli Hill in 1818.In 1819, Zwide made another expedition against the Zulus, but Shaka again changed his tactics, letting the Ndwandwe army penetrate his territory and responding with guerrilla warfare.
