Chiefage
(重定向自Chevage)
A chiefage, or chevage, according to Henry de Bracton, was a tribute by the head; or a kind of poll-money paid by those who held lands in villeinage, or otherwise, to their lords, in acknowledgement.
The word seems also to have been used for a sum of money annually given to a man of power, for his patronage and protection, as to their chief.
