But while the barons desired their presence as an aid against the Crown, the Crown itself desired it as a means of rendering taxation more efficient.

So long as the Great Council remained a mere assembly of magnates it was necessary for the King's ministers to treat separately with the other orders of the state as to the amount and assessment of their contributions.

The grant made in the Great Council was binding only on the barons and prelates who made it; but before the aids of the boroughs, the Church, or the shires could reach the royal treasury, a separate negotiation had to be conducted by the officers of the Exchequer with the reeves of each town, the sheriff and shire-court of each county, and the archdeacons of each diocese.

Bargains of this sort would be the more tedious and disappointing as the necessities of the Crown increased in the later years of Edward, and it became a matter of fiscal expediency to obtain the sanction of any proposed taxation through the presence of these classes in the Great Council itself.
The effort however to revive the old personal attendance of the lesser baronage which had broken down half a century before could hardly be renewed at a time when the increase of their numbers made it more impracticable than ever; but a means of escape from this difficulty was fortunately suggested by the very nature of the court through which alone a summons could be addressed to the landed knighthood.
