Life
Amarma was the son of a woman named Aisa, who was a daughter of a man named Othman. It is unclear if this Othman corresponds to one of the mais of this name (Othman I, Othman II, or Othman III Kalinumuwa). The German researcher Dierk Lange believes on unclear grounds that Amarma's father was Bir III Othman.{{Cite book |last=Lange |first=Dierk |url=https://unesdoc.unesco.org/ark:/48223/pf0000184287 |title=General history of Africa, IV: Africa from the twelfth to the sixteenth century |date= |website= |publisher=University of California |year=1984 |isbn=978-92-3-101710-0 |editor-last=Niane |editor-first=Djibril Tamsir |pages=261 |language=en |chapter=The kingdoms and peoples of Chad}}
Amarma became mai in 1450, succeeding Muhammad III. He ruled very briefly, being succeeded by Muhammad IV in 1451. Nothing is recorded of Amarma's reign.
