Magna Carta sealed at Runnymede
English barons forced King John to seal a charter at Runnymede on June 15, 1215, after he had lost nearly every military campaign he attempted and had responded by raising taxes and imprisoning dissenting nobles. The charter's central clause — no free man shall be seized or imprisoned except by the lawful judgment of his peers or the law of the land — is the direct ancestor of habeas corpus. John repudiated it within weeks. The Pope annulled it in August. But reissues in 1216, 1217, 1225, and 1297 anchored it in English law.
Of Magna Carta's 63 clauses, only three are still law in England today — but those three include the clauses establishing the liberty of the Church, the liberties of the City of London, and the requirement that trial happen 'by the law of the land.' The rest either became irrelevant or got absorbed into later statutes.
04 · Feudal Hierarchy
With Rome's collapse, the consensus mechanism in Europe fractured into two overlapping systems. Kings inherited power through bloodline. The Church ratified kings through coronation, and resolved doctrinal disputes through ecumenical councils of bishops. Between kings and kings, the feudal oath of fealty was the binding contract: personal, hierarchical, revocable only by death or excommunication. The first cracks in this system — Magna Carta, the Icelandic Althing, early parliaments — showed up as early as the 10th century but wouldn't compound into anything systemic for another 500 years.
