Mizrahi Jews in Israel constitute one of the largest Jewish sub-groups among Israeli Jews, numbering about 681,400 people of full or partial Mizrahi Jewish descent as of 2008. The other dominant sub-group are the Israeli Ashkenazi Jews and Sephardic Jews. Often Mizrahi and North African Sephardic Jews in Israel are grouped together due to the similarity of their history under Muslim rule and an overwhelming migration out of their countries of residence during the 20th century.
