ORIGIN
USAGE
Formerly, there were two types of crime to which the term treason was applied: petty treason (the crime of murdering one's master) and high treason (the crime of betraying one's country). As a classification of offense, the crime of petty treason was abolished in 1828. In modern use, the term high treason is now often simply called treason.
