The Treason Act 1423 (2 Hen.6 c.17) was an Act of the Parliament of England.
 It made it high treason for a person who had been indicted for treason to escape from prison (whether they were guilty of the original allegation of treason or not).
 This form of treason was abolished by the Treason Act 1547, although the Act was formally repealed in 1863.
The Treason Act (Ireland) 1765 (5 Geo 3 c. 21 (I.)) was an Act of the former Parliament of Ireland which gave defendants in trials for high treason under the Treason Act 1351 the right to be represented by counsel and the right to be given a copy of the indictment in advance of their trial.
 (These rights had been available under English law since the Treason Act 1695, and under Scottish law since that Act was extended to Scotland by the Treason Act 1708.)
 The Act's long title was "An Act for the better regulating of trials in cases of high treason under the statute of the twenty fifth of Edward the third" (sic).
 It was repealed by the Treason Act 1945, by which time it had long been obsolete.
The Treason Act 1795 (sometimes also known as the Treasonable and Seditious Practices Act) (36 Geo.
 3 c. 7) 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 Treason (Ireland) Act 1854 (17 & 18 Vict.
 c. 26) is an Act of the Parliament of the United Kingdom of Great Britain and Ireland.
 It extended part of the Treason Act 1708 to Ireland, specifically the rules about giving the defendant advance notice of the witnesses and jurors in his case.
 It was repealed by the Treason Act 1945, which abolished the unique procedural rules which applied in treason cases.
The Sedition Act 1661 (13 Car 2 St 1 c 1) was an Act of the Parliament of England, although it was extended to Scotland in 1708.
 Passed shortly after the Restoration of Charles II, it is no longer in force, but some of its provisions continue to survive today in the Treason Act 1695 and the Treason Felony Act 1848.
 One clause which was included in the Treason Act 1695 was later adapted for the United States Constitution.
Marcus Simon Sarjeant (born 1964) is a Briton who fired six blank shots at Queen Elizabeth II as she rode down The Mall to the Trooping the Colour ceremony in 1981.
An Acte agaynst counterfeting of forrayne Coyne (4 Hen.
 7 c. 18) was an Act of the Parliament of England passed in 1488.
 It made it high treason to counterfeit coinage from other countries.
 (It was already treason to counterfeit English coins, under the Treason Act 1351.)
 It was repealed by the Treason Act 1553, but another Act passed later in the same year recreated the offence.
The Treason Act 1415 (3 Hen.
 5 st.2 c.6) was an Act of the Parliament of England which made clipping coins high treason, punishable by death.
 (It was already treason to counterfeit coins.)
 The Act was repealed by the Treason Act 1553, and then revived again in 1562.
 The Act originally only protected English coins, but was later extended in 1575 to cover foreign coins "current" within England.
 By this time the Coin Act 1572 had already made it misprision of treason to clip foreign coins "not" current within the Realm.
The Treason Act 1842 (5 & 6 Vict.
 c.51) is an Act of the Parliament of the United Kingdom of Great Britain and Ireland.
 It was passed early in the reign of Queen Victoria.
 It was last used in 1981 to prosecute Marcus Sarjeant.
On 6 February 2017, the Sapphire Jubilee of Queen Elizabeth II, marking sixty-five years of her reign, occurred.
 The longest-reigning monarch in British history, Queen Elizabeth II was the first British monarch to have a sapphire jubilee.
 This Jubilee featured blue stamps from the Royal Mail, commemorative coins from the Royal Mint, and a reissue of an official 2014 portrait of Queen Elizabeth II by David Bailey.
 In this official portrait the Queen wears sapphire jewellery which she received as a wedding present from her father.
 The Jubilee also involved a gun salute at the Tower of London, a gun salute in Green Park, gun salutes in several other places around the United Kingdom, and the ringing of the bells in Westminster Abbey.
 Theresa May, the Prime Minister of the United Kingdom, congratulated Queen Elizabeth II in regard to the occasion, saying in part, "I know the nation will join with me today in celebrating and giving thanks for the lifetime of service Her Majesty the Queen has given to our country and to the Commonwealth."
