evidence: Mswati II (born c. 1825, near Manzini [now in Swaziland]—died August 1865, Swaziland) was a Southern African king and son of Sobhuza I. Mswati II was the greatest of the Dlamini-Ngwane kings, and the Swazi (as the Dlamini-Ngwane came to be called) take their name from him. He extended his kingdom northward into Rhodesia (now Zimbabwe), including territory since lost by the Swazi. Mswati was the son of Sobhuza I by his wife Thandile. He succeeded to the kingship on his father’s death sometime in 1839–40, but he began his effective rule when he was circumcised (a rite of passage signifying attainment of maturity) in 1845. He dealt with internal rebellion, pressures resulting from Boer invasions into the eastern Transvaal, and land rivalries with Mpande’s Zulu in the Ingwavuma River area. He expanded the control of Sobhuza’s original chieftaincy to include much of modern Swaziland’s Lowveld, creating one of the most powerful nations of Southern Africa. After the death of the Gaza king Soshangane (c. 1858–59), Mswati’s people interfered in the Gaza succession in a long-running series of wars and clashes. By 1865 the Swazi were hegemonic in the lowlands to the west of Delagoa Bay. In August 1865, however, Mswati died prematurely at the height of his success. His successors, Ludvongo and, after 1874, Mbandzeni, were unable to preserve Swazi power against Boer land claims and pursuit of minerals.
