The ancestors of the Iraqw are credited as the builders of the Iron Age settlement at Engaruka in Northern Tanzania. Complex irrigation systems supporting intensive agriculture supported an estimated peak population of 40,000. It is recognised as the largest abandoned system of irrigated agricultural fields and terraces in sub-Saharan Africa.[14][15][16]

The Bantu expansion from West Africa likely happened in several stages.[87] 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".[86] Ndembwike says 100–200 AD.[88]
Several durations are given by sources, including 38,[89][90] 40[91] and 45[92] 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.[93]
There is no exact figure for the number of deaths in the Maji Maji Rebellion. German officials at the time estimated 75,000.[94] Most sources say over 200,000.[94][95][96]
