Zara Yaqob
Zar'a Ya`qob or Zera Yacob
(Ge'ez ዘርአ:ያዕቆብ "zar'ā yāʿiqōb", English: "Descendant of Jacob"; 1399 – 26 August 1468) was the Emperor ("nəgusä nägäst") of Ethiopia, and a member of the Solomonic dynasty who ruled under regnal name Kwestantinos
I (Ge'ez ቈስታንቲኖስ "qʷastāntīnōs") or Constantine I, from the old province of Shewa, where the capital of the Amhara emperors was located before the post-16th-century Oromo migrations and the destructive war with Gran Ahmad.
Born at Telq in the province of Fatajar (now part of the Oromia Region, near the Awash River), Zara Yaqob was the youngest son of Dawit I and his youngest wife, Igzi Kebra.
The British expert on Ethiopia, Edward Ullendorff, stated that Zara Yaqob "was unquestionably the greatest ruler Ethiopia had seen since Ezana, during the heyday of Aksumite power, and none of his successors on the throne – excepted only the emperors Menelik II and Haile Selassie – can be compared to him."
Paul B. Henze repeats the tradition that the jealousy of his older brother Tewodros I forced the courtiers to take Zara Yaqob to Tigray where he was brought up in secret, and educated in Axum and at the monastery of Debre Abbay.
While admitting that this tradition "is invaluable as providing a religious background for Zar'a-Ya'iqob's career", Taddesse Tamrat dismisses this story as "very improbable in its details.
" The professor notes that Zara Yaqob wrote in his "Mashafa Berhan" that "he was brought down from the royal prison of Mount Gishan only on the eve of his accession to the throne."
