The mikveh is a ritual bath prescribed by ancient Jewish law for the rite of purification. It had particular significance for Jewish women, who were required to immerse themselves in the mikveh following their menstrual periods or after childbirth in order to become ritually pure and permitted to resume sexual activity. The practice has been jettisoned by many Jews but continues to be observed today, not only in Orthodox communities but also by feminists, queer Jews, and others who have reinterpreted the ritual.
