In the 1970s and early 1980s, the Beta Israel were required to undergo a modified conversion ceremony involving immersion in a mikveh (ritual bath), a declaration accepting Rabbinic law, and, for men, a "hatafat dam brit" (symbolic recircumcision). Avraham Shapira later waived the "hatafat dam brit" stipulation, which is only a requirement when the "halakhic" doubt is significant. More recently, Shlomo Amar has ruled that descendants of Ethiopian Jews who were forced to convert to Christianity are "unquestionably Jews in every respect". With the consent of Ovadia Yosef, Amar ruled that it is forbidden to question the Jewishness of this community, pejoratively called Falash Mura in reference to their having converted.
