 Evidence of agriculture and iron use dates from about the 4th century and people speaking languages ancestral to current Sotho and Nguni languages began settling no later than the 11th century.The Swazi settlers, then known as "the Ngwane" (or "bakaNgwane"), before entering Swaziland had been settled on the banks of the Pongola River and prior to that in the area of the Tembe River near present-day Maputo.Continuing conflict with the Ndwandwe people pushed them further north, with Ngwane III establishing his capital at Shiselweni at the foot of the Mhlosheni hills.
