Swaziland, officially the Kingdom of Swaziland (Swazi: Umbuso weSwatini), and sometimes called Ngwane or eSwatini, 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.
