Kilimanjaro in the context of Hans Meyer (geographer)

The geography of North Africa has been reasonably well known among Europeans since classical antiquity in Greco-Roman geography. Northwest Africa (the Maghreb) was known as either Libya or Africa, while Egypt was considered part of Asia.

European exploration of sub-Saharan Africa begins with the Age of Discovery in the 15th century, pioneered by the Kingdom of Portugal under Henry the Navigator. The Cape of Good Hope was first reached by Bartolomeu Dias on 12 March 1488, opening the important sea route to India and the Far East, but European exploration of Africa itself remained very limited during the 16th and 17th centuries. The European powers were content to establish trading posts along the coast while they were actively exploring and colonizing the New World. Exploration of the interior of Africa was thus mostly left to the Muslim slave traders, who in tandem with the Muslim conquest of Sudan established far-reaching networks and supported the economy of a number of Sahelian kingdoms during the 15th to 18th centuries.

Africa is a continent comprising 63 political territories, representing the largest of the great southward projections from the main mass of Earth's surface. Within its regular outline, it comprises an area of 30,368,609 km (11,725,385 sq mi), excluding adjacent islands. Its highest mountain is Kilimanjaro; its largest lake is Lake Victoria.

Separated from Europe by the Mediterranean Sea and from much of Asia by the Red Sea, Africa is joined to Asia at its northeast extremity by the Isthmus of Suez (which is transected by the Suez Canal), 130 km (81 mi) wide. For geopolitical purposes, the Sinai Peninsula of Egypt – east of the Suez Canal – is often considered part of Africa. From the most northerly point, Ras ben Sakka in Tunisia, at 37°21′ N, to the most southerly point, Cape Agulhas in South Africa, 34°51′15″ S, is a distance approximately of 8,000 km (5,000 mi); from Cap-Vert, 17°31′13″W, the westernmost point, to Ras Hafun in the Somali Puntland region, in the Horn of Africa, 51°27′52″ E, the most easterly projection, is a distance (also approximately) of 7,400 km (4,600 mi).

This is an incomplete list of the highest mountains of Africa. Peaks with less than 500 metres (1,640 ft) of topographic prominence (such as Mount Kenya's Nelion and Lenana peaks) are considered sub-peaks rather than independent mountains, and thus are not included.

The highest African mountain is Kilimanjaro, which has three peaks, named Kibo, Mawenzi and Shira, of which Kibo is the tallest and Mawenzi is sufficiently prominent to be a mountain. Mount Kenya is the second highest mountain in Africa which also has three main peaks, namely Batian, Nelion and Lenana Point.

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.

Johann Ludwig Krapf (11 January 1810 – 26 November 1881) was a German missionary in East Africa, as well as an explorer, linguist, and traveler. Krapf played an important role in exploring East Africa with Johannes Rebmann. They were the first Europeans to see Mount Kenya with the help of Akamba who dwelled at its slopes and Kilimanjaro. Ludwig Krapf visited Ukambani, the homeland of the Kamba people, in 1849 and again in 1850. He successfully translated the New Testament to the Kamba language. Krapf also played a key role in exploring the East African coastline, especially in Mombasa.

The Volcanic Seven Summits are the highest volcanoes on each of the seven continents, just as the Seven Summits are the highest peaks on each of the seven continents. Two of the Volcanic Seven Summits are also on the Seven Summits list. Kilimanjaro and Mount Elbrus, which were formed volcanically, are the highest peaks of their respective continents.
