Swaziland, officially the Kingdom of Swaziland, 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. At no more than 200 kilometres (120 mi) north to south and 130 kilometres (81 mi) east to west, Swaziland is one of the smallest countries in Africa.
