Coming of age is a young person's transition from being a child to being an adult. The specific age at which this transition takes place varies between societies, as does the nature of the change. It can be a simple legal convention or can be part of a ritual or spiritual event, as practiced by many societies. In the past, and in some societies today, such a change is associated with the age of sexual maturity (puberty), especially menarche and spermarche. In others, it is associated with an age of religious responsibility. Particularly in western societies, modern legal conventions which stipulate points at around the end of adolescence and the beginning of early adulthood (most commonly 18, with the range being 16–21) when adolescents are generally no longer considered minors and are granted the full rights and responsibilities of an adult) are the focus of the transition. In either case, many cultures retain ceremonies to confirm the coming of age, and coming-of-age stories are a well established sub-genre in literature, film industry, and other forms of media.
In certain states in Ancient Greece, such as Sparta and Crete, adolescent boys were expected to enter into a mentoring relationship with an adult man, in which they would be taught skills pertaining to adult life, such as hunting, martial arts and fine arts.

The puberty ritual for the young Roman male involved shaving his beard and taking off his bulla, an amulet worn to mark and protect underage youth, which he then dedicated to his household gods, the Lares. He assumed the toga virilis ("toga of manhood"), was enrolled as a citizen on the census, and soon began his military service. Traditionally, the ceremony was held on the Liberalia, the festival in honor of the god Liber, who embodied both political and sexual liberty, but other dates could be chosen for individual reasons.
Rome lacked the elaborate female puberty rituals of ancient Greece, and for girls, the wedding ceremony was in part a rite of passage for the bride.
