Parliament 401 I The knights of the shire and the burgesses were from I the start conscious of the financial purpose which drew f them to Parliament. Especially was this purpose em- phasised by the circumstances which attended the sum- mons of the Model Parliament and the events of the two succeeding years. Parliament was a taxing body from the first. It was natural then that the first great contest with the king should have been financial and that the %dL£2S^^ 'aave been control .over taxation. Conscious control of taxaKoirwaFtheTasis of all that Parliament came to do in government which lay ^)utside of the royal initiative. Something must be said t of the development of the taxing idea since early post- ^.^juest times and the circumstances of Parliament's a; ^.rtion of -control in the reign of Edward III. "^ l*,1> -r1 «' A.—When the king got together the different estates in Parliament and taxes were dealt with, it was evidently upon the assumption that taxal^ij^^ all classes were_conc^ned, B^^^^^J^^on. It has beenlsKown that for a considerable time after the Norman Conquest there was no understanding of taxation in the modern sense.I The king had various sources of revenue and means of supplying the needs of government, but his attention was fixed upon classes of men. Each class had a specialty, in some cases based upon private contract or proprietary relations, for supplying the royal needs. The king made his demands upon this, that, and the other class of the population as opportunity dictated and upon this, that, and the other different ground. Although the action of later kings, such as John and Henry III., tended toward the transmuting of these old grounds into a public obligation, yet the system gradually passed into disuse sion, or at most in a few instances for two or three years. There was a change in this respect in the fifteenth century through the development of the tunnage and poundage taxes. See below, pp. 406, 427. 1S. K. Mitchell, Taxation Under John and Henry III., p, 2. This is an important authority on taxation in the pre-Parliamentary period.
