migration. Between the 14th and 15th centuries, large medieval Southeast African kingdoms and states emerged, such as the Buganda, Bunyoro and Karagwe kingdoms of Uganda and Tanzania. During the early 1960s, the Southeast African nations achieved independence from colonial rule. Southern Africa Settlements of Bantu-speaking peoples, who were iron-using agriculturists and herdsmen, were already present south of the Limpopo River by the 4th or 5th century displacing and absorbing the original Khoisan speakers. They slowly moved south, and the earliest ironworks in modern-day KwaZulu-Natal Province are believed to date from around 1050. The southernmost group was the Xhosa people, whose language incorporates certain linguistic traits from the earlier Khoisan inhabitants. They reached the Fish River in today's Eastern Cape Province. Monomotapa was a medieval kingdom (c. 1250–1629), which existed between the Zambezi and Limpopo rivers of Southern Africa in the territory of modern-day Zimbabwe and Mozambique. Its old capital was located at Great Zimbabwe. In 1487, Bartolomeu Dias became the first European to reach the southernmost tip of Africa. In 1652, a victualling station was established at the Cape of Good Hope by Jan van Riebeeck on behalf of the Dutch East India Company. For most of the 17th and 18th centuries, the slowly expanding settlement was a Dutch possession. In 1795, the Dutch colony was captured by the British during the French Revolutionary Wars. The British intended to use Cape Town as a major port on the route to Australia and India. It was later returned to the Dutch in 1803, but soon afterward the Dutch East India Company declared bankruptcy, and the Dutch (now under French control) and the British found themselves at war again. The British captured the Dutch possession yet again at the Battle of Blaauwberg, commanded by Sir David Blair. The Zulu Kingdom was a Southern African tribal state in what is now KwaZulu-Natal in southeastern South Africa. The small kingdom gained world fame during and after their defeat in the Anglo-Zulu War. During the 1950s and early 1960s, most sub-Saharan African nations achieved independence from colonial rule. Demographics Population According to , the population of sub-Saharan Africa was 1.1 billion in 2019. The current growth rate is 2.3%. The UN predicts for the region a population between 2 and 2.5 billion by 2050 with a population density of 80 per km2 compared to 170 for Western Europe, 140 for Asia and 30 for the
