A *hauberk *fief; known in AnNor. as a fief de haubert. It was also known as a fief loricae. Orig. the Norman term for a knight with a *mail hauberk - a term of distinction, as not all Norman knights had one. In England the distinction was unnecessary: all enfeoffed knights were required to possess a hauberk. Feudum loricae and feudum militis (a knight's fief) were effectively one and the same. [< Lat. feudum = a fief + lorica = mail] -
Cf. Enfeoff
