Swaziland, officially the Kingdom of Swaziland (Umbuso weSwatini), and sometimes called Ngwane or Swatini, is a landlocked country in Southern Africa, bordered to the north, south and west by South Africa, and to the east by Mozambique. The nation, as well as its people, are named after the 19th century king Mswati II.

Swaziland is a small country, no more than 200 kilometres (120 mi) north to south and 130 kilometres (81 mi) east to west. The western half is mountainous, descending to a lowveld region to the east. The eastern border with Mozambique and South Africa is dominated by the escarpment of the Lebombo Mountains. The climate is temperate in the west, but may reach 40 °C (104 °F) in summer in the lowveld. Rainfall occurs mainly in the summer and may reach 2 metres (6.6 ft) in the west.

The area that Swaziland now covers has been continuously inhabited since prehistory. Today, the population is primarily ethnic Swazis whose language is siSwati, though English is spoken as a second language. The Swazi people descend from the southern Bantu who migrated from Central Africa in the 15th and 16th centuries. The Anglo-Boer War saw the United Kingdom make Swaziland a protectorate under its direct control. Swaziland gained independence in 1968. Swaziland is a member of the Southern African Development Community, the African Union, and the Commonwealth of Nations. The head of state is the king, who appoints the prime minister and a small number of representatives for both chambers of parliament. Elections are held every five years to determine the majority of the representatives. A new constitution was adopted in 2005.

Mswati III (born Makhosetive Dlamini on April 19, 1968) is the King of Swaziland and head of the Swazi Royal Family. In 1986, he succeeded his father Sobhuza II as ruler of the southern African kingdom. He is generally considered to be one of the last absolute monarchs in the world, as he has the authority to appoint the country's Prime Minister, members of the cabinet, and the judiciary. However, he is bound to a certain degree by Swazi traditions and he does not have the authority to choose his heir.

Mswati III is known for his taste for luxury and his practice of polygamy (although at least two wives are appointed by the state), and has been criticized abroad for pursuing his personal interests at the expense of his country, one of the poorest in the world. In 2001 he attempted to curb the AIDS epidemic by invoking an ancient chastity rite, the umchwasho, that banned women under the age of 18 from sex. Within Swaziland, Mswati is a respected and largely popular figure. However, his policies and opulent lifestyle have also triggered domestic protests and international criticism.
