Timeline of English Law
Explore 800+ years of legal history — from Magna Carta to the modern era. Click any event to learn about its lasting significance.
Magna Carta
King John sealed the Magna Carta at Runnymede under pressure from rebellious barons. It established that the King was subject to the law, guaranteed the right to a fair trial, and limited arbitrary royal taxation.
Statute of Merton
The oldest English statute still partly in force, enacted at a meeting of the King's council at Merton Priory. It addressed land law, the status of children born before marriage, and the enclosure of common land.
First elected Parliament — de Montfort's Parliament
Simon de Montfort summoned the first Parliament to include elected representatives from towns and counties, alongside the lords and clergy. Though de Montfort was killed months later, the precedent endured.
Statute of Westminster II
A sweeping legislative package enacted under Edward I that reformed land law, created the entailed estate (fee tail), and expanded the writ system that governed access to royal courts.
Statute Quia Emptores
Prohibited subinfeudation — the practice of tenants creating new feudal relationships by granting land to sub-tenants. Instead, land could only be transferred by substitution.
Year Books begin
Anonymous law reporters began compiling the Year Books — the earliest systematic reports of court proceedings in England. Written in Law French, they recorded arguments and judicial reasoning.
Treason Act 1351
Defined high treason for the first time in statute, including compassing the King's death, levying war against the King, and counterfeiting the Great Seal. It distinguished high treason from petty treason.
Justices of the Peace Act 1361
Formalised the role of Justices of the Peace (magistrates), giving local gentlemen the power to arrest and try criminals. It established the magistrates' court system.
Rise of the Court of Chancery
The Lord Chancellor began hearing petitions from subjects who could not obtain justice in the common law courts. The Court of Chancery developed its own body of rules — equity — to supplement and correct the common law.
Fortescue's De Laudibus Legum Angliae
Sir John Fortescue, Chief Justice of the King's Bench, wrote this influential treatise praising English law and comparing it favourably to continental civil law systems.
Statute of Uses 1535
Henry VIII enacted this statute to close a tax loophole. Landowners had been placing land 'in use' (an early form of trust) to avoid feudal dues payable on death. The statute converted equitable interests into legal ones.
Statute of Wills 1540
For the first time, landowners were permitted to leave their freehold land by will. Previously, land passed automatically by the rules of inheritance and could not be devised.
East India Company chartered
Queen Elizabeth I granted a royal charter to the East India Company, creating one of the first joint-stock companies with a monopoly on English trade with the East Indies.
Calvin's Case (1607)
The Court of Exchequer Chamber ruled that Robert Calvin, born in Scotland after James VI became James I of England, was a natural-born subject of both kingdoms and could own land in England.
Dr Bonham's Case (1610)
Chief Justice Coke declared that 'when an Act of Parliament is against common right and reason… the common law will control it and adjudge such Act to be void.' The College of Physicians had tried to fine and imprison Dr Bonham.
Petition of Right 1628
Parliament presented this petition to Charles I, asserting four fundamental liberties: no taxation without Parliament's consent, no imprisonment without cause, no quartering of soldiers on citizens, and no martial law in peacetime.
Abolition of the Star Chamber
Parliament abolished the Court of Star Chamber, which had become an instrument of royal tyranny under Charles I. The court had operated without juries, used torture, and imposed arbitrary punishments.
Bushel's Case (1670)
Juror Edward Bushel was imprisoned for acquitting William Penn of unlawful assembly. Chief Justice Vaughan ruled that jurors could not be punished for their verdicts, establishing jury independence.
Habeas Corpus Act 1679
Strengthened the ancient writ of habeas corpus, requiring that anyone detained be brought before a court to determine whether their imprisonment was lawful. It imposed penalties on officials who failed to comply.
Bill of Rights 1689
Following the Glorious Revolution, Parliament enacted the Bill of Rights, which declared the rights and liberties of subjects and settled the succession of the Crown. It prohibited the Crown from suspending laws, levying taxes, or maintaining a standing army without Parliament's consent.
Entick v Carrington
The Court of Common Pleas ruled that a general warrant issued by the Secretary of State to search for and seize papers was unlawful. Lord Camden held that every invasion of private property must be authorised by law.
Somerset v Stewart — slavery incompatible with English law
Lord Mansfield ruled that James Somerset, an enslaved man brought to England, could not be forcibly removed from the country. He held that slavery had no basis in English common law.
Slavery Abolition Act 1833
Abolished slavery throughout the British Empire (with exceptions for territories controlled by the East India Company). Provided £20 million in compensation to slave owners and introduced a system of 'apprenticeship' for former enslaved people.
M'Naghten Rules — the insanity defence
Following Daniel M'Naghten's acquittal for the murder of the Prime Minister's secretary on grounds of insanity, the House of Lords formulated the test for the insanity defence: the defendant must show they were labouring under such a defect of reason from disease of the mind as not to know the nature and quality of the act, or that it was wrong.
Judicature Acts 1873–1875 — fusion of law and equity
The Supreme Court of Judicature Acts created a single Supreme Court of Judicature (now the Senior Courts) with both common law and equitable jurisdiction. Law and equity could be administered by the same courts.
Carlill v Carbolic Smoke Ball Co
The Court of Appeal held that an advertisement promising £100 to anyone who used the smoke ball as directed and still caught influenza was a binding unilateral contract. Mrs Carlill's performance of the conditions was sufficient acceptance.
Donoghue v Stevenson — the neighbour principle
The House of Lords held that a manufacturer owed a duty of care to the ultimate consumer. Lord Atkin formulated the 'neighbour principle': you must take reasonable care to avoid acts or omissions which you can reasonably foresee would injure your neighbour.
Bolam v Friern Hospital Management Committee
Established the standard of care for medical professionals — a doctor is not negligent if acting in accordance with a practice accepted by a responsible body of medical opinion.

Brexit referendum and Article 50 litigation
The UK voted to leave the EU. In R (Miller) v Secretary of State [2017], the Supreme Court held that the government could not trigger Article 50 without an Act of Parliament, as withdrawal would change domestic legal rights.
R v Jogee — Joint enterprise corrected
The Supreme Court held that the law of joint enterprise had taken a 'wrong turn' 30 years ago. Foresight of what a co-defendant might do is evidence of intent, not a substitute for it.
R (UNISON) v Lord Chancellor — Tribunal fees struck down
