  1. ^ Sources vary as to the exact timescale of the migration of Khoisan from Southern Africa. Nurse & Spear say "as long as twenty thousand years ago".[68]
  2. ^ The Bantu expansion from West Africa likely happened in several stages.[69] Sources vary as to the exact timescale of the arrival of Bantu people to East Africa. Nurse & Spear say from "twenty-five hundred years ago".[68] Ndembwike says 100–200 AD.[70]
  3. ^ Several durations are given by sources, including 38,[71][72] 40[73] and 45[74] minutes, but the 38 minute duration is the most often quoted. The variation is due to confusion over what actually constitutes the start and end of a war. Some sources take the start of the war as the order to open fire at 09:00 and some with the start of actual firing at 09:02. The end of the war is usually put at 09:40 when the last shots were fired and the palace flag struck, but some sources place it at 09:45. The logbooks of the British ships also suffer from this with St George indicating that cease-fire was called and Khalid entered the German consulate at 09:35, Thrush at 09:40, Racoon at 09:41 and Philomel and Sparrow at 09:45.[75]
  4. ^ There is no exact figure for the number of deaths in the Maji Maji Rebellion. German officials at the time estimated 75,000.[76] Most sources say over 200,000.[76][77][78]
