Zambia, which is officially the Republic of Zambia (Tonga: Cisi ca Zambia; Lozi: Naha la Zambia; Nyanja: Dziko la Zambia), is a landlocked country at the crossroads of Central, Southern and East Africa. Its neighbors are the Democratic Republic of the Congo to the north, Tanzania to the north-east, Malawi to the east, Mozambique to the southeast, Zimbabwe and Botswana to the south, Namibia to the southwest, and Angola to the west. The capital city of Zambia is Lusaka, located in the south-central part of Zambia. The population is concentrated mainly around Lusaka in the south and the Copperbelt Province to the north, the core economic hubs of the country.
Originally inhabited by Khoisan peoples, the region was affected by the Bantu expansion of the thirteenth century. Following European explorers in the eighteenth century, the British colonised the region into the British protectorates of Barotziland-North-Western Rhodesia and North-Eastern Rhodesia towards the end of the nineteenth century. These were merged in 1911 to form Northern Rhodesia. For most of the colonial period, Zambia was governed by an administration appointed from London with the advice of the British South Africa Company.On 24 October 1964, Zambia became independent of the United Kingdom and prime minister Kenneth Kaunda became the inaugural president. Kaunda's socialist United National Independence Party (UNIP) maintained power from 1964 until 1991. Kaunda played a key role in regional diplomacy, cooperating closely with the United States in search of solutions to conflicts in Southern Rhodesia (Zimbabwe), Angola, and Namibia. From 1972 to 1991 Zambia was a one-party state with the UNIP as the sole legal political party under the motto "One Zambia, One Nation". Kaunda was succeeded by Frederick Chiluba of the social-democratic Movement for Multi-Party Democracy in 1991, beginning a period of social-economic growth and government decentralisation. Zambia has since become a multi-party state and has experienced several peaceful transitions of power.
Zambia contains abundant natural resources, including minerals, wildlife, forestry, freshwater and arable land. In 2010, the World Bank named Zambia one of the world's fastest economically reformed countries. The Common Market for Eastern and Southern Africa (COMESA) is headquartered in Lusaka.
