Both
August Dillmann and
Carlo Conti Rossini studied surviving Abyssinian
regnal lists and grouped them into three (lists A–C) and eight (lists A–H) types respectively. Alla Amidas appears on the following lists: Apart from Dillmann's list A/Rossini's list C, the lists are consistent in naming
Tazena as Alla Amida's successor and most name
Saladoba as his predecessor. However, only the first list in the above table provides any reign lengths. List B explicitly dates the arrival of the
Nine Saints to his reign, however at least one version of the list instead dates this event to the previous reign. Two manuscripts, called the
Gedle Aregawi and
Gedle Pentelewon, explicitly state that Alla Amidas was the son of Saladoba and father of Tazena. The latter text also precisely dates the arrival of the Nine Saints to the sixth year of his reign. The
Gedle Pentelewon states that the saints stayed for one year and nine months, while the
Gedle Pentelewon states they stayed for nine years, three years during the reign of Alla Amidas and six years during the reign of his successor Tazena. Ethiopian historian Sergew Selassie theorised that all of the saints, except
Abba Pantelewon and
Abba Liqanos, did not favour the accession of Tazena to the throne, and this is why they left Aksum, although the hagiographies preferred to claim they left because they wished to proselytize their religion. The
1922 regnal list of Ethiopia dated Alla Amidas' reign to 478–486 (
Ethiopian Calendar) and placed his reign between Saladoba and Tazena. However, Wolfgang Hahn and Vincent West dated his reign to the late 530s to 550s based on his coinage. == Notes ==
