The Caprivi Strip, also known simply as Caprivi, is a geographic salient protruding from the northeastern corner of Namibia. It is bordered by Botswana to the south and Angola and Zambia to the north. Namibia, Botswana and Zambia meet at a single point at the eastern tip of the Strip, which also comes within 150 m (490 ft) of Zimbabwe thus nearly forming a quadripoint. Botswana and Zambia share a 150-metre (490 ft) border at the crossing of Kazungula. The territory was acquired by then-German South West Africa in order to provide access to the Zambezi River and consequently a route to the east coast of the continent and German East Africa. The route was later found not to be navigable because of the location of the Victoria Falls, one of the world's largest waterfalls, about 65 kilometres (40 miles) east of the Caprivi Strip.[1]
