1911 Encyclopædia Britannica/Gumus
GUMUS, or Gumz, Negroes of the Shangalla group of tribes, dwelling in the mountainous district of Fazogli on the Sudan-Abyssinian frontier. They live in independent groups, some being mountaineers while others are settled on the banks of the Blue Nile. Gumz in the native tongue signifies “people,” and the sub-tribes have distinctive names. The Gumus are nature-worshippers, God and the sun being synonymous. On ceremonial occasions they carry parasols of honour (see Shangalla).
