Swaziland, officially the Kingdom of Swaziland ( or ; Swazi: Umbuso weSwatini ; sometimes called kaNgwane or Eswatini), is a sovereign state in Southern Africa. It is neighboured by  Mozambique to its east and by South Africa to its north, west and south. The country and its people take their names from Mswati II, the 19th-century king under whose rule Swazi territory was expanded and unified.
