David Livingstone in the context of "Quelimane"

Slave raiding is a military raid for the purpose of capturing people and bringing them from the raid area to serve as slaves. Once seen as a normal part of warfare, it is nowadays widely considered a war crime. Slave raiding has occurred since antiquity. Some of the earliest surviving written records of slave raiding come from Sumer (in present-day Iraq). Kidnapping and prisoners of war were the most common sources of African slaves, although indentured servitude or punishment also resulted in slavery.

The many alternative methods of obtaining human beings to work in indentured or other involuntary conditions, as well as technological and cultural changes, have made slave raiding rarer.

Explorers are listed below with their common names, countries of origin (modern and former), centuries of activity and main areas of exploration.

Johannes Rebmann (January 16, 1820 – October 4, 1876), sometimes anglicised as John Rebman, was a German missionary, linguist, and explorer credited with feats including being the first European, along with his colleague Johann Ludwig Krapf, to enter Africa from the Indian Ocean coast. In addition, he was the first European to find Kilimanjaro. News of Rebmann's discovery was published in the Church Missionary Intelligencer in May 1849, but disregarded as mere fantasy for the next twelve years. The Geographical Society of London held that snow could not possibly occur let alone persist in such latitudes and considered the report to be the hallucination of a malaria-stricken missionary. It was only in 1861 that researchers began their efforts to measure Kilimanjaro. Expeditions to Tanganyika between 1861 and 1865, led by the German Baron Karl Klaus von der Decken, confirmed Rebmann's report. Together with his colleague Johann Ludwig Krapf they were also the first Europeans to visit and report Mount Kenya. Their work there is also thought to have had effects on future African expeditions by Europeans, including the exploits of Sir Richard Burton, John Hanning Speke, and David Livingstone.

Rebmann spent 29 years in East Africa. Much of his work there consisted in linguistic investigations, especially into the Swahili, Mijikenda, and Chichewa languages.

The British Central Africa Protectorate (BCA) was a British protectorate proclaimed in 1889 and ratified in 1891 that occupied the same area as present-day Malawi: it was renamed Nyasaland in 1907. British interest in the area arose from visits made by David Livingstone from 1858 onward during his exploration of the Zambezi area. This encouraged missionary activity that started in the 1860s, undertaken by the Universities' Mission to Central Africa, the Church of Scotland and the Free Church of Scotland, and which was followed by a small number of settlers. The Portuguese government attempted to claim much of the area in which the missionaries and settlers operated, but this was disputed by the British government. To forestall a Portuguese expedition claiming effective occupation, a protectorate was proclaimed, first over the south of this area, then over the whole of it in 1889. After negotiations with the Portuguese and German governments on its boundaries, the protectorate was formally ratified by the British government in May 1891.

The London Missionary Society was an interdenominational evangelical missionary society formed in England in 1795 at the instigation of Welsh Congregationalist minister Edward Williams. It was largely Reformed in outlook, with Congregational missions in Oceania, Africa, and the Americas, although there were also Presbyterians (notable for their work in China), Methodists, Baptists, and various other Protestants involved. It now forms part of the Council for World Mission.

Slavery existed in the Sultanate of Zanzibar until 1909. Slavery and slave trade existed in the Zanzibar Archipelago for at least a thousand years. During the 19th century, the rise of large-scale clove and coconut plantations under Omani Arab rule led to a significant expansion of the slave system. By some estimates, enslaved people constituted up to two-thirds of the archipelago's population at its peak. Zanzibar was internationally known as a major player in the Indian Ocean slave trade, where slaves from the Swahili coast of Eastern Africa were trafficked across the Indian Ocean to Oman in the Arabian Peninsula during the Zanzibar slave trade.

During the 19th-century, Britain conducted an international abolitionist campaign against the Sultanate and restricted and eventually abolished the slavery and slave trade in Zanzibar via a number of treaties between 1822 and 1897, resulting in the end of the slave trade and finally the end of slavery itself in 1909.

Victoria Falls (Lozi: Mosi-oa-Tunya, "Thundering Smoke/Smoke that Rises"; Tonga: Shungu Namutitima, "Boiling Water") is a waterfall on the Zambezi River, located on the border between Zambia and Zimbabwe. It is one of the world's largest waterfalls, with a width of 1,708 m (5,604 ft). The region around it has a high degree of biodiversity in both plants and animals.

Archaeology and oral history describe a long record of African knowledge of the site. Although known to some European geographers before the 19th century, Scottish missionary David Livingstone identified the falls in 1855, naming them Victoria Falls after Queen Victoria. Since the mid-20th century, the site has been a major tourist destination. Zambia and Zimbabwe both have national parks and tourism infrastructure at the site. Research in the late 2010s found that precipitation variability due to climate change is likely to alter the character of the falls.

Livingstone is a city in Southern Province, Zambia. Lying 10 km (6 mi) to the north of the Zambezi River, it is a tourist attraction due to its proximity to the Victoria Falls and its road and rail connections to Victoria Falls, Zimbabwe, the resort town on the opposite side of the falls. A historic British colonial city, its present population was enumerated at 177,393 inhabitants at the 2022 census. It is named after David Livingstone, the Scottish explorer and missionary who was the first European to explore the area. From 1911 until 1935, it served as the first capital of Northern Rhodesia. From 1907 to 2011, when replaced by Choma, Livingstone was the capital of Zambia's Southern Province.

Baron Karl Klaus (Carl Claus) von der Decken (born 8 August 1833 in Kotzen, Brandenburg, Germany; died 2 October 1865 near Bardera, Somalia) was a German explorer of eastern Africa and the first European to attempt to climb Mount Kilimanjaro.

Following a stint in the military, von der Decken first travelled to eastern Africa in May 1860. There he explored the region around Lake Nyasa, only a year after David Livingstone had been the first European to reach the area. The following year, von der Decken set out from Mombasa to survey the Kilimanjaro massif. During the journey inland, he met the young English geologist Richard Thornton (1838–1863) – who had left Livingstone's Zambezi expedition – and invited him to accompany him to Kilimanjaro. When the massif loomed into view, it was the first time it had been sighted by Europeans since Johannes Rebmann had been the first European to see it in 1848.
