1399, from Anglo-Fr.
legaunce "loyalty of a liege-man to his lord," from O.Fr.
legeance, from
liege (see
liege); erroneously associated with L.
ligare "to bind;" corrupted in spelling by confusion with the now-obsolete legal term
allegeance "alleviation." General fig. sense of "recognition of claims to respect or duty" is attested from 1732.
