Overview

Under the law of the United Kingdom, high treason is the crime of disloyalty to the Crown. Offences constituting high treason include plotting the murder of the sovereign; having sexual intercourse with the sovereign's consort, with his eldest unmarried daughter, or with the wife of the heir to the throne; levying war against the sovereign and adhering to the sovereign's enemies, giving them aid or comfort; and attempting to undermine the lawfully established line of succession. Several other crimes have historically been categorised as high treason, including counterfeiting money and being a Catholic priest.

High treason was formerly distinguished from petty treason, a treason committed against a subject of the sovereign, the scope of which was limited by statute to the murder of a legal superior. Petty treason comprised the murder of a master by his servant, of a husband by his wife, or of a bishop. Petty treason ceased to be a distinct offence from murder in 1828.

Considered to be the most serious of offences, high treason was often met with extraordinary punishment, because it threatened the security of the state. A particularly horrific manner of execution known as hanging, drawing and quartering was often employed. The last treason trial was that of William Joyce, who was executed in 1946.
