Treason is the crime of attacking a state authority to which one owes allegiance. This typically includes acts such as participating in a war against one's native country, attempting to overthrow its government, spying on its military, its diplomats, or its secret services for a hostile and foreign power, or attempting to kill its head of state. A person who commits treason is known in law as a traitor.
Capital punishment in the United Kingdom predates the formation of the UK, having been used within the British Isles from ancient times until the second half of the 20th century. The last executions in the United Kingdom were by hanging, and took place in 1964; capital punishment for murder was suspended in 1965 and finally abolished in 1969. Although unused, the death penalty remained a legally defined punishment for certain offences such as treason until it was completely abolished in 1998; the last execution for treason took place in 1946. In 2004 the 13th Protocol to the European Convention on Human Rights became binding on the United Kingdom; it prohibits the restoration of the death penalty as long as the UK is a party to the convention.
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; committing adultery with the sovereign's consort, with the sovereign's 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.
The Treachery Act 1940 was an Act of the Parliament of the United Kingdom effective during World War II to facilitate the prosecution and execution of enemy spies, suspended afterwards, and repealed in 1968 or 1973, territory depending. The law was passed on 23 May 1940, in the month after Nazi Germany invaded France and Winston Churchill became prime minister.
The "Bloody Code" was a series of laws in England, Wales and Ireland in the 18th and early 19th centuries which mandated the death penalty for a wide range of crimes. It was not referred to by this name in its own time; the name was given later owing to the sharply increased number of people given the death penalty, even for crimes considered minor by 21st century standards.
The Treason Act 1351 is an Act of the Parliament of England which codified and curtailed the common law offence of treason. No new offences were created by the statute. It is one of the earliest English statutes still in force, although it has been very significantly amended. It was extended to Ireland in 1495 and to Scotland in 1708. The Act was passed at Westminster in the Hilary term of 1351, in the 25th year of the reign of Edward III and was entitled "A Declaration which Offences shall be adjudged Treason". It was passed to clarify precisely what was treason, as the definition under common law had been expanded rapidly by the courts until its scope was controversially wide. The Act was last used to prosecute William Joyce in 1945 for collaborating with Germany in World War II.

One clause which was included in the Treason Act 1695 was later adapted for the United States Constitution.

On 19 July 1797 Parliament extended the scope of that Act to cover all coins made of copper. The Acts are now repealed.
