The Short Answer
Magna Carta was a 63-clause peace charter that King John sealed at Runnymede on 15 June 1215, and most of it dealt with narrow feudal grievances — inheritance fees, widows' rights, debt collection, forest law, fish weirs, and standard weights and measures — rather than general liberty; only a handful of clauses, above all clause 39 on judgment by lawful peers or the law of the land, later became the basis for broader ideas of due process. It was a negotiated settlement between King John and a group of rebellious barons, and Pope Innocent III annulled it within ten weeks of its sealing.
The Answer in Full
A peace treaty, not a bill of rights
Magna Carta was negotiated as a peace settlement between King John and a group of rebel barons who had occupied London; Archbishop Stephen Langton mediated the terms, and the king met the rebels at Runnymede, near Windsor Castle, on 15 June 1215, where the charter was sealed. The barons who forced the terms on John had specific, personal grievances, mainly over inheritance payments ("reliefs"), the seizure of widows' property, debt collection practices, and John's demands for scutage and other feudal levies after the loss of Normandy in 1204 had pushed him to squeeze English revenue harder. The result was, as its opening line states, a grant "to all freemen of our kingdom" of listed liberties, sealed by John and addressed to his archbishops, bishops, abbots, earls, barons, and officials. It went beyond the barons' immediate complaints into a wider proposal for political reform, but that reform focused on free men, not on serfs and unfree labourers, who made up most of the population.
The bulk of the text: feudal housekeeping
Most of the 63 clauses are narrowly technical. Clause 2 fixed the inheritance "relief" an heir owed the Crown at a set scale, for instance £100 for an earl's whole barony and 100 shillings for a knight's fee. Clauses 3 through 8 covered wardship, marriage, and widows: clause 7 stated a widow was to have her marriage portion and inheritance "immediately and without difficulty" after her husband's death, and clause 8 provided that no widow was to be compelled to remarry so long as she wished to remain unmarried. Clauses 9 and 10 restrained the seizure of debtors' land while they had movable goods enough to pay, and shielded a Jewish moneylender's debtor's heir from interest accruing during his minority. Clause 13 confirmed London's "ancient liberties and free customs," clause 33 ordered the removal of fish weirs from the Thames and Medway (a concession to merchants who wanted the rivers clear for navigation), and clauses 35 and 36 standardised weights and measures of wine, ale, corn, and cloth across the kingdom, and made writs concerning life or limb free of charge. None of this reads as a statement of universal liberty; it is a settlement of specific 1215 complaints.
The clauses that outlasted the rest
A small number of clauses proved far more consequential than their original context suggests. Clause 12 stated that no scutage or aid was to be levied "save by the common counsel of our kingdom," except for three traditional feudal payments — a principle later invoked, centuries on, in disputes over taxation without consent. Clause 39 declared that no free man was to be arrested, imprisoned, dispossessed, outlawed, or exiled, nor would the king proceed against him, except by the lawful judgment of his peers or by the law of the land, and clause 40 promised that the king would sell to no one, nor deny or delay, right or justice. Clause 61, the so-called "security clause," created a council of 25 barons empowered to seize the king's castles and lands if John failed to make amends within 40 days of being notified of a breach — a mechanism that, in effect, authorised the barons to make war on their own king if he reneged. These clauses drew on an existing tradition rather than inventing rights from nothing: the principle that a free man's peers alone could judge him already appears in sources such as the early twelfth-century Leges Henrici Primi, and Magna Carta itself echoed Henry I's coronation charter of 1100.
What it did not establish
Magna Carta did not create trial by jury, though jury trial, once it developed, came to be seen as resting on the charter's promise of judgment by one's peers; the jury's actual origins predate 1215. It did not establish habeas corpus, which traces to procedures already present in instruments such as the 1166 Assize of Clarendon. And its liberties were not universal: they were granted to "freemen," a legally and economically privileged category that excluded the unfree peasantry who formed most of the population, and several clauses (10 and 11, on debts owed to Jewish moneylenders) reflect the period's institutionalised anti-Jewish discrimination rather than any conception of equal rights. The charter also created no lasting means of enforcement: it lacked machinery to compel the king if he simply ignored it, and it left untouched the sensitive questions of who advised the king and how patronage was distributed.
It failed almost immediately, then came back
The 1215 charter was extracted under duress, and King John treated it that way: he appealed to his feudal overlord, Pope Innocent III, who on 24 August 1215 issued a papal bull, Etsi karissimus, declaring the charter "null and void of all validity for ever" and threatening excommunication against anyone who tried to enforce it. The First Barons' War followed within weeks. Only after John died in October 1216, leaving a nine-year-old heir, Henry III, in a kingdom still at war with rebel barons and an invading French force, was a revised version reissued to win the barons back; further reissues followed in 1217 and 1225, and the 1225 version, which dropped the unenforceable 25-baron security clause, was the one eventually entered into English statute law in 1297. Today only four clauses of the original 63 remain in force in England and Wales — parts of clause 1, clause 13 on London's liberties, and clauses 39 and 40 (renumbered as clause 29 in the 1297 statute) on due process.
How We Know
The text of Magna Carta survives in four original 1215 exemplifications (engrossments) sealed and distributed at the time, held today by the British Library, Lincoln Castle, and Salisbury Cathedral, alongside chronicle accounts and the papal bull annulling it; scholarly editions and translations by the British Library and specialist projects such as the Magna Carta Project reconcile the Latin original against these copies.

Common Misconceptions
The beliefMagna Carta established trial by jury.
The recordJury trial's origins predate Magna Carta; the charter guaranteed judgment by one's lawful peers, and it was only as jury trial developed later that it came to be seen as resting on that guarantee, per the House of Commons Library and Library of Congress accounts.
The beliefMagna Carta gave rights and freedoms to the English people generally.
The recordThe charter's liberties were granted to 'freemen,' a privileged legal category, and did not cover serfs or unfree labourers, who formed the majority of the population; the charter for the most part created or recognised privileges rather than general rights, according to the House of Commons Library.
The beliefMagna Carta was a single, lasting document that immediately became the law of the land in 1215.
The recordThe 1215 charter was annulled by Pope Innocent III within ten weeks, on 24 August 1215, and only entered English statute law through the reissued 1297 version; the original 1215 text has since been repealed in its entirety, though three of its clauses survive via the 1297 reissue.
The beliefMagna Carta established the right of habeas corpus.
The recordThe principle of habeas corpus predates Magna Carta and appeared earlier in the Assize of Clarendon of 1166, according to the British Institute of Human Rights.

Terms to Know
Clause (or chapter) — One of the 63 distinct provisions of Magna Carta; the original 1215 text was continuous and unnumbered, and the now-standard numbering was applied by later editors.
Scutage — A payment made to the Crown in place of personal military service, one of the levies clause 12 said could only be raised with the kingdom's common consent.
Relief — A fee an heir owed the Crown to inherit land held directly of the king; clause 2 fixed these fees on a set scale.
The security clause (clause 61) — The provision creating a council of 25 barons empowered to seize the king's lands and castles if he breached the charter and did not make amends.
Free man — A legally privileged status distinct from serfs and unfree labourers; Magna Carta's liberties were granted to free men, not to the unfree majority of the population.
Papal bull — A formal, sealed document issued by the Pope; Innocent III used one, Etsi karissimus, to annul Magna Carta in August 1215.

What the Record Cannot Answer
How closely did royal officials in the years immediately after 1215 actually comply with Magna Carta's specific clauses, such as the removal of fish weirs or the standardisation of weights and measures? — The charter's text tells us what was promised, but not how consistently it was enforced on the ground in the immediate aftermath of a document annulled within ten weeks of its sealing.
What was Archbishop Stephen Langton's precise personal role in drafting the specific wording of clause 61, as opposed to mediating the broader settlement? — Historians disagree on whether the security clause reflects Langton's political thinking or the barons' own feudal customs, and the surviving record does not resolve his exact contribution to that clause.

○ REPORTED
Did clause 61's security clause (the council of 25 barons) originate as Archbishop Langton's proposal for constitutional limits on the monarchy, or as the barons' assertion of a feudal right of formal defiance against a lord who had broken his contract?
Some historians read clause 61 as reflecting emerging ideas about limited monarchy, possibly promoted by Langton. vs Other historians read it as an expression of the barons' established feudal right to renounce allegiance to a lord who violated his obligations, rather than a novel constitutional idea.
◑ CONTESTEDWould settle it: Direct evidence of the drafting process behind clause 61 is lacking; only chronicler Matthew Paris's later account records John's dissatisfaction with it, so the question likely cannot be settled without a new primary source documenting the barons' or Langton's intent.
Does clause 39's guarantee of judgment 'by the lawful judgment of his peers or by the law of the land' mean trial by a jury of one's social equals, or does it refer more narrowly to the procedural stage of a lawful court process?
A traditional and popular reading holds that clause 39 is the direct ancestor of trial by jury, guaranteeing judgment by one's equals. vs A more cautious scholarly reading, reflected in the Magna Carta Project's commentary, holds that the clause restates an already-established principle that no free man could be punished without a prior judgment in a lawfully constituted court, and treats the connection to jury trial as a later development read back onto the clause.
◑ CONTESTEDWould settle it: Further contemporary thirteenth-century evidence of how clause 39 was actually invoked in court practice immediately after 1215 would help settle how contemporaries understood its scope.
How closely did royal officials in the years immediately after 1215 actually comply with Magna Carta's specific clauses, such as the removal of fish weirs or the standardisation of weights and measures?
