History of Africa the early part of the 19th century was undergoing its Industrial Revolution. Nationalist rivalries and prestige were at play. Acquiring African colonies would show rivals that a nation was powerful and significant. These factors culminated in the Scramble for Africa. Knowledge of Africa increased. Numerous European explorers began to explore the continent. Mungo Park traversed the Niger River. James Bruce travelled through Ethiopia and located the source of the Blue Nile. Richard Francis Burton was the first European at Lake Tanganyika. Samuel White Baker explored the Upper Nile. John Hanning Speke located a source of the Nile at Lake Victoria.
Mountains of the Moon (Africa) Speke in 1862 sought the source of the White Nile in the Great Lakes region. Henry Morton Stanley finally found glacier-capped mountains possibly fitting Diogenes's description in 1889 (they had eluded European explorers for so long due to often being shrouded in mist). Today known as the Rwenzori Mountains, the peaks are the source of some of the Nile's waters, but only a small fraction, and Diogenes would have crossed the Victoria Nile to reach them. Many modern scholars doubt that these were the Mountains of the Moon described by Diogenes, some holding that his reports were wholly fabricated. G.W.B.
