The Swazi are a Bantu Nguni-speaking people in southeastern Africa, chiefly in Swaziland and South Africa. Besides their language, Siswati, they speak Afrikaans in South Africa and English in South Africa and Swaziland. There have been more Swazi people living in South Africa than in Swaziland since the late 1800s. The Swazi people and the Kingdom of Swaziland today are named after Mswati II, who became king in 1839. Their royal lineage can be traced to a chief named Dlamini I; this is still the royal clan name. About three-quarters of the clan groups are Nguni; the remainder are Sotho and Tsonga descendants. These groups have intermarried freely. There are slight differences among Swazi groups, but Swazi identity extends to all those with allegiance to the twin monarchs Ingwenyama "the Lion" (the king) and Indlovukati "the She-Elephant" (the queen mother).
