The Kingdom of eSwatini is the correct match for Swaziland. In April 2018, King Mswati III officially renamed the country from the Kingdom of Swaziland to the Kingdom of eSwatini to mark the 50th anniversary of independence and avoid international confusion with Switzerland [2]. Regarding the other options, historical records show that Nyasaland became Malawi upon independence in 1964, while Bechuanaland became Botswana in 1966. Southern Rhodesia was renamed Zimbabwe in 1980 [1]. Ceylon is the former name of Sri Lanka, not Zimbabwe. The name 'eSwatini' translates to 'land of the Swazis' in the local language and represents a return to indigenous nomenclature following the colonial era [2].
