Lusaka is the capital and largest city of Zambia. It is located in the southern part of the central plateau, at an elevation of about 1,300 metres (4,265 feet). It has a population of about 1.7 million (2010 census). It is a commercial centre as well as the centre of government, and the four main highways of Zambia head north, south, east and west from it. The two main languages spoken in Lusaka are English and Nyanja (a Bantu language). English is the official language.
Lusaka was the site of a village named after its headman Lusakasa, which, according to history, was located at Manda Hill, near where the Zambia's National Assembly building now stands. In the Nyanja language, Manda means graveyard. The area was expanded by European (mainly British) settlers in 1905 with the building of the railway.
In 1935, due to its fairly central location, its situation on the railway and at the crossroads of the Great North Road and Great East Road, it was chosen to replace Livingstone as the capital of the British colony of Northern Rhodesia.
After the federation of Northern and Southern Rhodesia in 1953, it was a centre of the independence movement amongst some of the educated elite that led to the creation of the Republic of Zambia. In 1964, Lusaka became the capital of the newly independent Zambia.
In recent years, Lusaka has become a popular urban settlement for Zambians and tourists alike. Its central nature and fast growing infrastructure sector has increased donor confidence and as such Zambians are seeing signs of development in the form of job creation, housing, etc. Consequently, it is thought that with proper and effective economic reforms, Lusaka as well as Zambia as a whole will develop considerably. Lusaka is home to a diverse community of foreigners, many of whom work in the aid industry as well as diplomats, representatives of religious organizations and some business people.
