Zambia, in south-central Africa, is the continent's biggest copper producer and home to the Victoria Falls, one of the Seven Natural Wonders of the World. The Victoria Falls - also known locally as the ''Smoke that Thunders'' - are to be found along the Zambezi River and have UNESCO World Heritage status. They are one of the country's many natural features which have been enticing a growing number of tourists, along with the wide variety of wildlife to be found in large game parks. Another draw for visitors is the fact that Zambia has been peaceful and generally trouble-free, especially compared to some of the eight neighbours with which it shares a border. The neighbouring countries are the Democratic Republic of Congo to the north, Tanzania to the north-east, Malawi to the east, Mozambique, Zimbabwe, Botswana and Namibia to the south, and Angola to the west. The area of Zambia was colonised in the 1800s and ruled by Britain as Northern Rhodesia until 1964, when it made a peaceful transition to independence.
