History of Bat Mitzvah
The bat mitzvah ceremony is of relatively recent vintage, with the first American observance in 1922.
The first American bat mitzvah in 1922 initiated a ceremony that continues its development even today. Whereas the bat mitzvah in the liberal movements is now, in most synagogues, identical to the bar mitzvah. In traditional settings, where communal and religious values still dictate that women not take an active role in religious services, women are struggling with how to formulate a religiously acceptable, public ceremony to mark a girl's coming of age. One venue for the bat mitzvah not mentioned below is in a women's prayer service. Excerpted with permission from A Time for Every Purpose Under Heaven (Farrar, Straus and Giroux, LLC).
For larger and larger parts of the Jewish people, girls at 12 or 13 years of age are undertaking exactly the same ceremony as boys. For American Jews, this process famously began in 1922 when Rabbi Mordecai Kaplan, the founder of Reconstructionism, arranged for his daughter Judith to celebrate becoming a bat mitzvah at a public synagogue ceremony.
But in fact her ceremony did not involve a full aliyah to the Torah [going up to the Torah and reciting blessings over its reading], and was thus a much-diminished version of what boys did. It bore considerable resemblance to a way of celebrating this passage in the synagogue that some girls in Italy and France had begun even earlier, and Rabbi Kaplan may have used for his daughter's rite what he had heard or seen of an Italian ceremony.
Elsewhere, too, in Jewish life, girls entering adulthood had begun to take part in a public ceremony. Late in the 19th century, Joseph Hayyim Eliyahu ben Moshe of Baghdad, Ben Ish Hai. wrote (as translated by Howard Tzvi Adelman):
"And also the daughter on the day that she enters the obligation of the commandments, even though they don't usually make for her a seudah [celebratory meal], nevertheless that day will be one of happiness. She should wear Sabbath clothing and if she is able to do so she should wear new clothing and bless the Shehecheyanu prayer [for the One 'Who gives us life, lifts us up, and carries us to this moment'] and be ready for her entry to the yoke of the commandments. There are those who are accustomed to make her birthday every year into a holiday. It is a good sign, and this we do in our house."
Another bat mitzvah ceremony, in the synagogue, was celebrated in Lwow in 1902 by Rabbi Dr. Yehezkel Caro, "rabbi for the enlightened Jews."
What gave long-term importance to Judith Kaplan's moment was that American culture supported transfoming this hesitant beginning into wholehearted change. By the end of the 20th century, in almost all non-Orthodox congregations girls were celebrating their coming-of-age as b'not mitzvah through much the same ceremonies their brothers experienced.
