It was easy to give this principle a further extension by the choice of representatives of the lesser barons in the shire courts to which they were summoned; but it was only slowly and tentatively that this process was applied to the reconstitution of the Great Council. As early as the close of John's reign there are indications of the approaching change in the summons of "four discreet knights" from every county. Fresh need of local support was felt by both parties in the conflict of the succeeding reign, and Henry and his barons alike summoned knights from each shire "to meet on the common business of the realm." It was no doubt with the same purpose that the writs of Earl Simon ordered the choice of knights in each shire for his famous Parliament of 1265. Something like a continuous attendance may be dated from the accession of Edward, but it was long before the knights were regarded as more than local deputies for the assessment of taxation or admitted to a share in the general business of the Great Council. The statute "Quia Emptores," for instance, was passed in it before the knights who had been summoned could attend. Their participation in the deliberative power of Parliament, as well as their regular and continuous attendance, dates only from the Parliament of 1295. But a far greater constitutional change in their position had already taken place through the extension of electoral rights to the freeholders at large. The one class entitled to a seat in the Great Council was, as we have seen, that of the lesser baronage; and it was of the lesser baronage alone that the knights were in theory the representatives. But the necessity of holding their election in the County Court rendered any restriction of the electoral body physically impossible. The court was composed of the whole body of freeholders, and no sheriff could distinguish the "aye, aye" of the yeoman from the "aye, aye" of the lesser baron. From the first moment therefore of their attendance we find the knights regarded not as mere representatives of the baronage but as knights of the shire, and by this silent revolution the whole body of the rural freeholders were admitted to a share in the government of the realm.
