Eswatini derives its name from a later king named Mswati II. ''KaNgwane'', named for Ngwane III, is an alternative name for Eswatini, the surname of whose royal house remains ''Nkhosi Dlamini''. ''Nkhosi'' literally means "king". Mswati II was the greatest of the fighting kings of Eswatini, and he greatly extended the area of the country to twice its current size. The ''Emakhandzambili'' clans were initially incorporated into the kingdom with wide autonomy, often including grants of special ritual and political status. The extent of their autonomy, however, was drastically curtailed by Mswati, who attacked and subdued some of them in the 1850s.
