(2) Britain Explanation: England is treated as the place where the constitutional concept germinated, though the ancient Greek and Roman Republics, too, had such a facility. In England, Henry Fs proclamation of the Charter of Liberties in 1100 bound the king for the first time in his treatment of the clergy and the nobility. This idea was extended and refined by the English barony when they forced King John to sign Magna Carta in 1215. The most important single article of the Magna Carta, related to "habeas corpus", provided that the king was not permitted to imprison, outlaw, exile or kill anyone at a whim there must be due process of law first.
