Medieval warfare was dominated by the great proprietors. In the Chansons de Geste the king and his followers, the great lords and their honourable companions, ride out into battle. They are collectively the “chivalry”; a complex word whose meaning encompasses the notion of an armed elite, a style of war and a code of military behaviour in which personal honour is paramount. Within the chivalrous society there were evident differences of status, and the lesser did honourable service to the greater, yet there was a community of shared values.

The act by which arms were bestowed on a young man for the first time had long been an important “rite of passage”. In the eleventh century, it became a distinct Christian ritual for the making of a knight. In the first third
