Explain the circumstances behind the Magna Carta (1215) and identify its lasting principles of limited government and due process.
King John of England (ruled 1199-1216) lost a war for territory in France and then squeezed his own barons (powerful nobles) with heavy taxes to pay for it. Furious barons rebelled, cornered the king, and forced him to agree to a document at Runnymede in June 1215: the Magna Carta, Latin for "Great Charter." Most of its 63 clauses dealt with specific medieval grievances that mean little today, but a handful of principles buried inside it turned out to matter enormously for centuries afterward.
Clause 39 stated, in a commonly used English translation, that "no free man shall be seized, imprisoned, dispossessed, outlawed, exiled, or ruined in any way... except by the lawful judgment of his peers and the law of the land." That is an early seed of due process -- the idea that even a king cannot punish someone without a fair legal process. Other clauses limited the king's ability to tax without the consent of his barons' council -- an early ancestor of the idea "no taxation without representation" that will matter again when you study the American Revolution. King John tried to cancel the agreement almost immediately, and Magna Carta had little real effect in his lifetime -- but it was reissued by later kings and became a powerful symbol, cited centuries later by the English Bill of Rights (1689) and by the writers of the United States Constitution.
Mastery looks like: They can explain the circumstances of Magna Carta's creation, paraphrase Clause 39 accurately, and identify its later influence honestly, including its original limits.
Common stumbles: Treating Magna Carta as a modern-style bill of rights for everyone in 1215, rather than a narrow document whose principles only widened much later.
