treachery against the state, attempt to overthrow the government to which one owes allegiance
High treason, broadly defined, is an action which is grossly disloyal to one's country or
sovereign. Participating in a war against one's country, attempting to overthrow its government, or attempting to kill its head of state are perhaps the best-known examples of high treason.Historically, in
common law countries high treason was differentiated from
petty treason, which was the act of killing a lawful superior (such as a servant killing his master or mistress). It was, in effect, considered a more serious degree of
murder. As jurisdictions around the world abolished petty treason, the concept of petty treason gradually faded, and today use of the word "
treason" generally refers to "high treason." The law of some countries does not distinguish the two — for example, the
Constitution of the United States defines treason as something which, historically, would have been called high treason.
