Artifacts indicating human activity dating back to the early Stone Age 200,000 years ago have been found in the Kingdom of Swaziland. Prehistoric rock art paintings date from ca. 25,000 B.C. and continue up to the 19th century.
The earliest inhabitants of the area were Khoisan hunter-gatherers.They were largely replaced by the Bantu tribes during Bantu migrations who hailed from the Great Lakes regions of Eastern Africa. 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 Bantu people known as the Swazis established iron-working and settled farming colonies in the 15th century after crossing the Limpopo river. They experienced great economic pressure from the rival Ndwandwe clans from the south.
The country derives its name from a later king, Mswati I. However, Ngwane is an alternative name for Swaziland and Dlamini remains the surname of the royal house, while Nkosi means "king". Scholarly history of Swaziland shows that independent chiefdoms and small kingdoms dominated by various clans were initially conquered and incorporated into the growing Ngwane kingdom ruled by members of the Dlamini clan sometime in the 18th and 19th centuries, long before British colonisation.
According to Swazi royalist tradition, these clans came to be classified in the Dlamini kingdom as the Emakhandzambile category of clans ("those found ahead", e.g. the Gamedze), meaning that they were on the land prior to Dlamini immigration and conquest, as opposed to the Bomdzabuko ("true Swazi") who accompanied the Dlamini kings, and the Emafikemuva ("those who came behind") who joined the kingdom later. Emakhandzambile clans initially were incorporated with wide autonomy, and often in part by granting them special ritual and political status (cf. mediatisation), but the extent of their autonomy was drastically
