Mbabane, with an estimated population of 95,000 (2007), is the capital and largest city of Swaziland. It is located on the Mbabane River and its tributary the Polinjane River in the Mdimba Mountains. It is located in the district of Hhohho, of which it is also the capital. The average elevation of the city is 3,800 ft. The population (estimated) in 1987 was 30,000. The town grew after the nation's administrative centre moved from Bremersdorp in 1902. It derives its name from a Chief, Mbabane Kunene, who lived in the area when British settlers arrived. It is also a commercial hub for the surrounding region, while tin and iron were mined nearby.
