This article is an anthropological history of the bar/bat mitzvah ceremony in the Yishuv and Israel of the 1940s and the 1950s, when this ceremony radically grew in terms of the space, time, and economic resources devoted to it, as well as expanded to include girls. To explain that shift, I suggest distinguishing classic rites of initiation from the system of life-cycle ceremonies typical of modern consumer culture, which emphasizes the transition between temporal markers rather than social statuses and imposes no task on the birthday celebrant.
