In its modern form, the Jewish feminist movement can be traced to the early 1970s in the United States. According to Judith Plaskow, the main grievances of early Jewish feminists were women's exclusion from the all-male prayer group or "minyan", women's exemption from positive time-bound "mitzvot" (mitzvot meaning the 613 commandments given in the Torah at Mount Sinai and the seven rabbinic commandments instituted later, for a total of 620), and women's inability to function as witnesses and to initiate divorce in Jewish religious courts.
