Yemrehana Krestos

Yemrehana Krestos (called "Abraham" by Francisco Álvares) was negus of Ethiopia, and a member of the Zagwe dynasty. According to Taddesse Tamrat, he was the son of Germa Seyum, the brother of Tatadim; however the Italian scholar Carlo Conti Rossini published in 1902 a document that stated Yemrehana Krestos was the successor of Na'akueto La'ab, and succeeded by Yetbarak. According to a manuscript Pedro Páez and Manuel de Almeida saw at Axum, (where he is called "Imrah"), he ruled for 40 years a suspiciously round number.

Taddesse Tamrat describes him as the king of Ethiopia closest to a priest, noting that he insisted on ruling Ethiopia according to Apostolic canons. Stuart Munro-Hay speculates that "Abu Salih's description of the kings of Abyssinia as priests might have been based on information about this ruler that had reached Egypt. Francisco Alvarez also recorded the tradition that it was Yemrehana Krestos who began the tradition of confining rival heirs to the Imperial throne at Amba Geshen.
