What was discovered

An expedition from Zanzibar following the Arab caravan route to Ujiji, on the shore of a long, deep lake that Burton and Speke recognised as the head of the western Rift. It is the world's second-deepest lake.

A discovery only for Europeans: Swahili and Arab traders and riparian peoples knew it. Burton, ill, did not see Lake Victoria, which Speke found afterwards.

What it led to

  • Speke went on to Lake Victoria and the sources of the Nile
  • Livingstone and Stanley at Ujiji (1871)
  • mapping of the Great Lakes and the slave and ivory trade routes
