Aid, the term given to the payments, originally voluntary, made by a tenant to his lord under the feudal system. Aids afterwards became compulsory, and were exacted (1) for the ransom of the lord, (2) the expenses of marrying his eldest daughter, or (3) of making his eldest son a knight. This tax was abolished in 1672.

Aid was also used as the name for a subsidy granted to the king by Parliament as part of his revenue.
