Eswatini, officially the Kingdom of Eswatini and also known by its former official name Swaziland and formerly the Kingdom of Swaziland, is a landlocked country in Southern Africa. It is bordered by Mozambique to its northeast and South Africa to its north, west, south, and southeast. At no more than 200 km (120 mi) north to south and 130 km (81 mi) east to west, Eswatini is one of the smallest countries in Africa; despite this, its climate and topography are diverse, ranging from a cool and mountainous highveld to a hot and dry lowveld.

The Commonwealth of Nations, often simply referred to as the Commonwealth, is an international association of 56 member states, the vast majority of which are former territories of the British Empire from which it developed. They are connected through their use of the English language and historical-cultural ties. The chief institutions of the organisation are the Commonwealth Secretariat, which focuses on intergovernmental aspects, and the Commonwealth Foundation, which focuses on non-governmental relations among member states. Numerous organisations are associated with and operate within the Commonwealth.
