The following excerpt is from the March 21, 2017 article posted at OnlineEthiopia.net:
The Ethiopian Jews, who primarily relocated from Ethiopia to Israel through Israeli rescue missions in the 1980s, form a unique minority of today’s Israeli population. Back In Ethiopia, they were known as Falasha, meaning “strangers”, and have referred to themselves as Beta Israel, or “the house of Israel”. Their settlements were scattered in the northwestern area of Ethiopia and the border zone with the Sudan.
The approach and methodology of the conventional theory on the origins of the Ethiopian Jewry, as proposed by James Quirin, rejects the existence of an ancestral connection between the contemporary Ethiopian Jewish community and the ancient Israelite-Jews. Proponents of this theory trace the origins of the group to what they perceive as a local Ethiopian separatist movement within Christianity in the 14th-to-16th century.
