John Hanning Speke

John Hanning Speke was a British explorer whose East African expeditions identified Lake Victoria as a source of the Nile. His claim became central to a prolonged geographical dispute.

Lake Victoria: Africa’s largest lake by area, shared by Tanzania, Uganda, and Kenya. Speke identified this lake as the Nile’s principal source in 1858.
Richard Francis Burton: A British explorer, linguist, and writer who led the 1857–1858 East African expedition with Speke. Burton disputed Speke’s identification of Lake Victoria as the Nile’s source.
Royal Geographical Society: A British learned society founded in 1830 to advance geographical science and exploration. The society supported and publicized expeditions to resolve the Nile’s geography.
Nile basin: The drainage region whose waters flow into the Nile River and its tributaries. Speke’s discovery shifted attention toward the lakes and rivers of the upper Nile basin.
Richard Burton: A British explorer and scholar who traveled with Speke and challenged his conclusion about the Nile’s source. Burton’s disagreement turned their shared expedition into a public rivalry.
Source of the Nile: The headwaters from which the Nile River begins its course northward. Finding the Nile’s source was the central geographic question of Speke’s expeditions.
James Augustus Grant: A Scottish explorer who accompanied Speke on the 1860–1863 expedition to the Nile. Grant supported Speke’s Lake Victoria claim and helped document the journey.
Zanzibar: An East African archipelago and historic Indian Ocean trading center, now part of Tanzania. Speke’s expeditions began from Zanzibar, a major base for inland travel.
Nile controversy: A nineteenth-century dispute among explorers and geographers over the sources and course of the Nile. The disagreement between Speke and Burton became its most public episode.
Kagera River: A river system flowing into Lake Victoria from the south and west. Its tributaries complicate any simple claim that one point is the Nile’s source.
