Until the 1980s, a substantial population of Beta Israel / ቤተ እስራኤል / ביתא ישראל (Ethiopian Jews) resided in Ethiopia. About 4,000 Jews, who claim to be one of the lost tribes of Israel are estimated to still live in Ethiopia, along with many more members of two related ethno-religious groups, the Falash Mura and the Beta Abraham. The Falash Mura are Beta Israel who, while identifying as Jews, adopted elements of Christianity due to missionary efforts, and now practice a syncretic form of Ethiopian Judaism mixed with Christianity; they number about 150,000 people. The Beta Abraham are regarded as a medieval offshoot of the Beta Israel, having incorporated elements of traditional African religion, and number about 8,000. While both still identify as Beta Israel, they exist outside the main community. The official Beta Israel community leaders tentatively accept the Falash Mura, and have requested they be allowed to migrate to Israel. The Beta Abraham have historically been shunned by most other communities, having had a reputation of being "sorcerers". In certain Ethiopian towns and villages such as Wolleka, near the Ethiopian city of Gondar, the concentration of Ethiopian-Jews is still significant but the US now has a significantly greater numbers of Ethiopian-Jews than that of Ethiopia.
