Zambia, formally the Republic of Zambia, is a landlocked nation in Central, Southern, and East Africa, while it is most often referred to as being in Southern Africa at its most central point. The Democratic Republic of the Congo borders it to the north, Tanzania to the east, Malawi to the east, Mozambique to the southeast, Zimbabwe and Botswana to the south, Namibia to the southwest, and Angola to the west. Zambia's capital city, Lusaka, is situated in the country's south-central region. The population is centered mostly around Lusaka in the south and the Copperbelt Province in the north, the country's primary economic centres.
The area was originally populated by Khoisan peoples before being influenced by Bantu expansion in the thirteenth century. Following European explorers in the eighteenth century, the British colonised the area into the British protectorates of Barotseland-North-Western Rhodesia and North-Eastern Rhodesia in the late nineteenth century, including 73 tribes. Northern Rhodesia was formed in 1911 when these two countries combined. Zambia was ruled for the majority of the colonial era by an administration selected from London on the recommendation of the British South Africa Company.
Zambia gained independence from the United Kingdom on October 24, 1964, with Prime Minister Kenneth Kaunda serving as the initial president. From 1964 through 1991, Kaunda's socialist United National Independence Party (UNIP) ruled. Kaunda was a prominent figure in regional diplomacy, working closely with the US to find solutions to problems in Southern Rhodesia (Zimbabwe), Angola, and Namibia. From 1972 until 1991, Zambia was a one-party state, with UNIP being the only legal political party operating under Kaunda's slogan "One Zambia, One Nation." In 1991, Kaunda was replaced by Frederick Chiluba of the social-democratic Movement for Multi-Party Democracy, ushering in an era of socioeconomic progress and political decentralisation. Zambia has subsequently become a multi-party state with multiple peaceful leadership transfers.
Zambia is rich in natural resources such as minerals, wildlife, forests, freshwater, and arable land. Zambia was ranked one of the world's fastest-reforming economies by the World Bank in 2010. The headquarters of the Common Market for Eastern and Southern Africa (COMESA) are in Lusaka.
