Iguandu is a big civilization in Africa existed from 600 B.C.E. to 800 A.D.
It was situated first in centre of Africa but it was pretty strong and started to conquer other nations.
In 273 A.D. Igaundu leader called himself as "Bantu emperor".
Iguandu is anarcho-capitalistic-theocracy.
There is no infirmation about flags and other things and how this empire fell but language is pretty same like Sawahilli, so historicals still works on it.
