A Legal Maxim is an established principle or proposition. The Latin term, apparently a
variant on maxima, is not to be found in Roman law with any meaning exactly analogous to
that of a legal maxim in the Medieval or modern sense of the word, but the treatises of many
of the Roman jurists on Regular definitions, and Sententiae juris are, in some measure,
collections of maxims. Most of the Latin maxims developed in the Medieval era in European
countries that used Latin as their language for law and courts.
