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.
In English history, the penal laws were a series of laws that sought to enforce the State-decreed religious monopoly of the Church of England and, following the 1688 revolution, of Presbyterianism in Scotland, against the continued existence of illegal and underground communities of Catholics, nonjuring Anglicans, and Protestant nonconformists. The Penal laws also imposed various forfeitures, civil penalties, and civil disabilities upon recusants from mandatory attendance at weekly Sunday services of the Established Church. The penal laws in general were repealed in the early 19th-century due to the successful activism of Daniel O'Connell for Catholic Emancipation. Penal actions are civil in nature and were not English common law.
Sedition is overt conduct, such as speech or organization, that tends toward rebellion against the established order. Sedition often includes subversion of a constitution and incitement of discontent toward, or insurrection against, established authority. Sedition may include any commotion, though not aimed at direct and open violence against the laws. Seditious words in writing are seditious libel. A seditionist is one who engages in or promotes the interest of sedition.
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effective during World War II to facilitate the prosecution and execution of enemy spies, suspended afterwards, and repealed in 1968 or 1973, territory depending.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 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 Treason Act 1795 was one of the Two Acts introduced by the British government in the wake of the stoning of King George III on his way to open Parliament in 1795, the other being the Seditious Meetings Act 1795. The Act made it high treason to "within the realm or without compass, imagine, invent, devise or intend death or destruction, or any bodily harm tending to death or destruction, maim or wounding, imprisonment or restraint, of the person of ... the King". This was derived from the Sedition Act 1661, which had expired. The 1795 Act was originally a temporary Act which was to expire when George III died, but it was made permanent by the Treason Act 1817.
The Criminal Law Act 1967 is an act of the Parliament of the United Kingdom that made some major changes to English criminal law, as part of wider liberal reforms by the Labour government elected in 1966. Most of it is still in force.
Constructive treason is the judicial extension of the statutory definition of the crime of treason. For example, the English Treason Act 1351 declares it to be treason "When a Man doth compass or imagine the Death of our Lord the King". This was subsequently interpreted by the courts to include imprisoning the king, on the ground that history had shown that when a king is held captive by a usurper, he often dies in captivity. Despite legislative efforts to restrict the scope of treason, judges and prosecutors in common law jurisdictions still succeeded in broadening the reach of the offence by "constructing" new treasons. It is the opinion of one legal historian that:
The word "constructive" is one of the law's most useful frauds. It implies substance where none exists. There can be constructive contracts, constructive trusts, constructive fraud, constructive intent, constructive possession, and constructive anything else the law chooses to baptize as such. "Constructive" in this sense means "treated as". ... Constructive treason wasn't "real" treason but a vaguely defined, less potent category of conduct that the court deciding the particular case felt should be "treated as" treason. It was the perfect instrument of oppression, being virtually whatever the authorities wanted it to be.
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.
