The events of the next fifteen years, vital as they are to constitutional history, must be briefly gone over. It is the period of the Barons’ War and the Provisions of Oxford, and finally of Simon de Montfort’s famous Parliament of 1265. But the years did not intimately affect taxation, save as they provided more or less definitely for the body which should ultimately have control over the granting of taxes. Taxation was a prime cause of the baronial irritation which led to the trouble with the king, but the conflict was not a moving cause in the final attainment by Parliament of exclusive power over taxation. The chain of events, however, in so far as they are pertinent to the subject, must be traced. [Strife between king and Parliament] At the Hoketide Parliament[107] of 1255 the usual demand was made for an elective ministry and was refused;[108] at the adjourned session of this Parliament the following October, an aid to the king was denied on the distinct ground that the members, all magnates, had not been summoned according to the terms of Magna Carta.[109] The struggle, vain and threatening of future ill, went on through the next year, until by 1257 the king found himself plunged inextricably into debt, much of which was owing to the Pope. The latter had undertaken a war with Manfred with whom was lined up the Hohenstaufen power, to seat on the throne of Sicily Edmund Crouchback, Henry’s second son.[110] Henry owed him 135,000 marks, and it is said that the Londoners, the sheriffs, the clergy, and the Jews therefore suffered. The first Parliament of 1258 was held at London on the 9th April and sat for about a month. The purple robes in which Henry garbed his foreign favorites shone richly against the gray background of his asserted poverty, and their brilliance was enough to blind the eyes of the Parliament to his necessities. Wars were threatened on the northern and western borders, and the Pope was brandishing his sword of excommunication in case Henry continued his dilatory policy toward Apulia. Parliament refused his urgent plea for a tallage of one-third of the movables of the realm, reprehending the simplicity of the king in making his bargain with the Pope.[111] An outbreak was avoided by an adjournment until the 11th June at Oxford.
