Capital punishment in the United Kingdom predates the formation of the UK, having been used in Britain and Ireland 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 to be executed for treason was William Joyce, in 1946. In 2004, Protocol No. 13 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.
Petty treason or petit treason was an offence under the common law of England in which a person killed or otherwise violated the authority of a social superior, other than the king. In England and Wales, petty treason ceased to be a distinct offence from murder by virtue of the Offences against the Person Act 1828. It was abolished in Ireland in 1829. It never existed in Scotland. It has also been abolished in other common-law countries.
Arson in royal dockyards and armories was a criminal offence in the United Kingdom and the British Empire. It was among the last offences that were punishable by capital punishment in the United Kingdom. The crime was created by the Dockyards etc. Protection Act 1772 passed by the Parliament of Great Britain, which was designed to prevent arson and sabotage against vessels, dockyards, and arsenals of the Royal Navy.
The Treason Act 1351 is an Act of the Parliament of England wherethrough, according to William Blackstone, common law treason offences were enumerated and no new offences were, by statute, created. 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.
The Offences against the Person Act 1861 is an Act of the Parliament of the United Kingdom of Great Britain and Ireland. It consolidated provisions related to offences against the person from a number of earlier statutes into a single Act. For the most part these provisions were, according to the draftsman of the Act, incorporated with little or no variation in their phraseology. It is one of a group of Acts sometimes referred to as the Criminal Law Consolidation Acts 1861. It was passed with the object of simplifying the law. It is essentially a revised version of an earlier consolidation act, the Offences Against the Person Act 1828, incorporating subsequent statutes.

The Offences Against the Person Act 1828, also known as Lord Lansdowne's Act, was an act of the Parliament of the United Kingdom that consolidated for England and Wales provisions in the law related to offences against the person from a number of earlier piecemeal statutes into a single act. Among the laws it replaced was clause XXVI of Magna Carta, the first time any part of Magna Carta was repealed, and the Buggery Act 1533. The act also abolished the crime of petty treason.
The Offences Against the Person Act 1837 was an act of the Parliament of the United Kingdom that amended the law to lessen the severity of punishment of offences against the person, lessening the severity of the punishment of offences.
To be hanged, drawn and quartered was a method of torturous capital punishment used principally to execute men convicted of high treason in medieval and early modern Britain and Ireland. The convicted traitor was fastened to a hurdle, or wooden panel, and drawn behind a horse to the place of execution, where he was then hanged, emasculated, disembowelled, beheaded, and quartered. His remains would then often be displayed in prominent places across the country, such as London Bridge, to serve as a warning of the fate of traitors. The punishment was only ever applied to men; for reasons of public decency, women convicted of high treason were instead burned at the stake.
The Treason by Women Act (Ireland) 1796 was an act of the Parliament of the Kingdom of Ireland which reduced the penalty for women convicted of high treason and petty treason from death by burning to death by hanging. It was the Irish equivalent of the Treason Act 1790 passed by the Parliament of the Kingdom of Great Britain.
Aiding and abetting is a legal doctrine related to the guilt of someone who aids or abets another person in the commission of a crime. It exists in a number of different countries and generally allows a court to pronounce someone guilty for aiding and abetting in a crime even if he or she is not the principal offender. The words aiding, abetting and accessory are closely used but have differences. While aiding means providing support or assistance to someone, abetting means encouraging someone else to commit a crime. Accessory is someone who in fact assists "commission of a crime committed primarily by someone else". However, some jurisdictions have merged being an accessory before the fact with aiding and abetting.
The Coinage Offences Act 1832 was an act of the Parliament of the United Kingdom that consolidated England and Wales all legislation concerning the counterfeiting and clipping of coins into one act. Such conduct was often considered to be high treason: this act downgraded the offence to felony and abolished the death penalty for all coinage offences.
The Criminal Justice Act 1948 is an Act of the Parliament of the United Kingdom. It implemented several widespread reforms of the English criminal justice system, mainly abolishing penal servitude, corporal punishment, and the right of peers to be tried for treason and felony in the House of Lords. The act also dealt with more minor aspects of criminal law, such as the procedure regarding bail. Early versions of the bill attempted to abolish the death penalty, but this would not occur until 1965.
The Forgery Act 1837 was an act of the Parliament of the United Kingdom that abolished the punishment of the death penalty for all offences of forgery, substituting it for transportation or imprisonment.
The Crimes Act of 1790, formally titled An Act for the Punishment of Certain Crimes Against the United States, defined some of the first federal crimes in the United States and expanded on the criminal procedure provisions of the Judiciary Act of 1789.

The Act was the result of the efforts of the law reformer Sir Samuel Romilly MP, who had failed to pass a similar bill in 1813.
The Criminal Law Act 1827 was an act of the Parliament of the United Kingdom, applicable only to England and Wales. It abolished many obsolete procedural devices in English criminal law, particularly the benefit of clergy. It was repealed by the Criminal Law Act 1967.
